Genetic Engineering
Genetic engineers can alter the DNA of living organisms through techniques like selective breeding, recombinant DNA, polymerase chain reaction (PCR), and gel electrophoresis. Selective breeding has been used for thousands of years, while recombinant DNA was first used in the 1970s to combine DNA from different organisms. Genetically modified crops and animals can have benefits like increased disease resistance, higher yields, and the ability to produce human proteins, but they are also controversial. DNA analysis techniques like PCR and gel electrophoresis allow the unique identification of individuals for uses such as criminal investigations.

Introduction to Animal Biotechnology
1. The history of biotechnology can be divided into 3 stages - ancient, classical, and modern. Ancient biotech involved early applications related to food and shelter. Classical biotech built on these techniques and promoted fermentation. Modern biotech manipulates genetic information through techniques like genetic engineering.
2. Biotechnology has 5 main branches - animal, medical, environmental, industrial, and plant. Animal biotech improves livestock through techniques like artificial insemination, cloning, and transgenic animals. Medical biotech develops drugs and treatments.
3. Environmental biotech applies bioprocesses to clean pollution through bioremediation. Industrial biotech uses organisms to produce chemicals. Plant biotech engineers crops for desired traits like pest
Transgenic animal technology ppt
Transgenic animals are animals that have had a foreign gene deliberately inserted into their genome using recombinant DNA methodology. The first transgenic mice were created in 1980, and the first cloned mammal, Dolly the sheep, was born in 1996. There are three main methods for creating transgenic animals: DNA microinjection, embryonic stem cell-mediated gene transfer, and retrovirus-mediated gene transfer. Transgenic animals produce useful products like monoclonal antibodies, blood clotting factors, and human milk proteins. They are used for medical research, toxicology studies, pharmaceutical production, and analyzing gene expression regulation. However, some ethical concerns exist regarding animal suffering during transgenic research experiments.
Transgenic animals (1)
Transgenic animals are organisms whose genome has been altered by the addition of foreign DNA from other species. This document discusses the history of transgenic animals, including the first transgenic mice created in the 1970s. It describes various methods used to create transgenic animals, such as microinjection and viral vectors. The benefits and risks of transgenic animals are outlined. Applications include producing human proteins and studying human diseases. While transgenic animals show promise for agriculture, medicine, and industry, issues around safety, ethics, and environmental impacts require further consideration.
Genetic engineering2
Selective breeding involves breeding animals or plants with desired traits to increase those traits in future generations. Genetic variations arise from mutations that can occur naturally or be induced by factors like radiation. While most mutations are harmless, some can be beneficial or harmful, like cancer-causing mutations. Techniques like hybridization and genetic engineering allow further manipulation of organisms by combining genes from different species or rewriting DNA. Transgenic organisms containing genes from other species have potential applications in medicine, agriculture, and materials production, but also raise ethical issues.
Genetic engineering2
Selective breeding, mutations, and hybridization are methods that have been used for centuries to introduce desirable traits into organisms. More recently, genetic engineering techniques like DNA extraction, transgenic organisms, cloning, and gene editing have allowed for more direct manipulation of genes. While these advanced methods hold promise for applications like producing human proteins and saving endangered species, they also raise ethical concerns that require careful consideration.

Genetically modified animal organs for human transplantation.pptx
Genetically modified animals are created by inserting, modifying, or removing DNA sequences in a way that does not occur naturally in order to introduce new traits or characteristics. The first transgenic animal was created in 1982 by incorporating human growth hormone into a giant mouse's genome. Currently, rats and mice represent 95% of transgenic animals but other animals include chickens, pigs, cows, sheep and fish. Researchers have genetically modified pigs to not have viruses that could infect humans, making organ transplantation between animals and humans possible. Dolly the sheep was the first mammal cloned from an adult cell and lived at the Roslin Institute, giving birth to six lambs before being euthanized due to lung disease.
Recombinant
This document discusses various genetically modified animals and their uses. It describes how transgenic fruit flies are used in biological research to study the effects of genetic changes on development. It also discusses how genetically modified mosquitoes have been developed to combat the spread of malaria and dengue fever by containing a lethal gene. Finally, it summarizes that genetically modified animals have medical, agricultural, and industrial importance, including uses as disease models, producing pharmaceuticals, improving food production, and testing chemical toxicity.
History of transgenics
The document provides a detailed history of genetic engineering and transgenics from 1859 when Charles Darwin published On the Origin of Species laying the foundations for modern genetics, through key discoveries like DNA's structure in 1953 and the development of recombinant DNA techniques in the 1970s. It then outlines major milestones in genetic engineering for both research organisms and agricultural crops, including the first transgenic animals in the 1980s, approval of GM crops for commercialization in the 1990s, and ongoing advances and debates around the world.
Cloning 100809065228-phpapp01
This document provides an overview of cloning including:
1) Cloning occurs naturally in bacteria, plants and some animals. Scientists have cloned mammals including frogs, mice and sheep.
2) The history of cloning involved early experiments in the 1800s and major advances in the 1950s-1990s including cloning frogs and the birth of Dolly the sheep in 1996.
3) Scientists clone cells through techniques like blastomere separation, blastocyst division and somatic cell nuclear transfer which involves transferring the nucleus of a donor adult cell into an egg with its nucleus removed.
Cloning Bio-Informative
Cloning involves creating genetically identical copies of living organisms. Early cloning experiments in the 1900s involved separating sea urchin and salamander embryos. In 1952, frogs were successfully cloned using nuclear transfer. John Gurdon furthered this research in 1962 by cloning tadpoles using differentiated intestinal cells. His work demonstrated that specialized cells could be reprogrammed. Dolly the sheep, born in 1996, was the first mammal cloned from an adult somatic cell, proving nuclear transfer could produce viable offspring. Cloning research continues to provide insights into development and genetics while also having applications for producing therapies.
Trangenic animals
The document defines transgenic animals as organisms with DNA from another source inserted into their genome, making them genetically modified organisms (GMOs). It provides a brief historical background on early transgenic research and commercialization. The document then categorizes GMOs, describes common methods for producing transgenic animals like embryonic stem cell and pronucleus methods, and gives examples of transgenic mice, fish, cows, pigs, monkeys, and more. It discusses advantages like improved growth and traits, as well as disadvantages like unintended effects and breeding issues. Finally, it outlines applications like producing recombinant proteins, serving as disease models, and aiding medical research.
transgenic animals by apexa.pdf
Transgenic animals are created through manipulating an animal's DNA by introducing foreign genes. The first transgenic animals were mice created in 1974 by microinjecting genes into embryos. Common methods to create transgenic animals are DNA microinjection, retrovirus-mediated gene transfer, and embryonic stem cell-mediated gene transfer. Transgenic animals have applications in agriculture to improve traits like milk production, applications in medicine to produce pharmaceuticals, and industrial applications like producing spider silk proteins. While transgenic animals provide benefits, they also require special care and precautions to address potential health and breeding issues.
Transgenic animals by Kashikant Yadav
Transgenic animals are animals whose genomes have been modified by the addition or deletion of genes. Common methods to produce transgenic animals include DNA microinjection, retrovirus-mediated gene transfer, and embryonic stem cell-mediated gene transfer. Transgenic animals are produced for various economic, medical, and industrial applications such as increasing milk production in cows, developing disease models, and producing pharmaceuticals in the milk of transgenic animals. Proper housing and care is required to maintain transgenic animals.
Stem cell and Cloning

Gene Clo Ning
The document discusses different types of cloning technologies including DNA cloning, reproductive cloning, and therapeutic cloning. DNA cloning involves transferring a DNA fragment from one organism to a self-replicating vector like a bacterial plasmid to generate multiple copies. Reproductive cloning aims to generate an animal with the same nuclear DNA as another through somatic cell nuclear transfer, while therapeutic cloning seeks to produce human embryos for stem cell research. Both cloning techniques are controversial due to safety and ethical concerns.

13-3 cell transformation
This document discusses cell transformation, which is a change to a cell's DNA. It describes three methods of transforming cells:
1) Transforming bacteria cells using plasmids containing foreign DNA that can be inserted into the plasmid. The recombinant plasmids can then deliver the DNA into the bacterial cell.
2) Transforming plant cells either by using the bacterium Agrobacterium tumefaciens to transfer recombinant plasmids, or by using a gene gun to inject DNA-coated particles into plant cells.
3) Transforming animal cells by injecting foreign DNA directly into egg nuclei, or using gene replacement to "knock out" an existing gene.
13-2 manipulating DNA
The document describes the basic techniques of genetic engineering which include extracting DNA from cells, cutting DNA into fragments using restriction enzymes, separating DNA fragments through gel electrophoresis, amplifying DNA through polymerase chain reaction, and making recombinant DNA by cutting and recombining DNA from different species and inserting it into host cells. These techniques allow scientists to isolate, modify, and transfer genes between organisms.
12-4
This document discusses different types of mutations including gene mutations and chromosomal mutations. It describes point mutations such as single base substitutions, insertions, and deletions as well as frameshift mutations that can occur from insertions or deletions. It also discusses chromosomal mutations like duplications, inversions, translocations, and deletions. Non-disjunction during meiosis can result in aneuploidy with an extra or missing chromosome. Mutations can be harmful and cause genetic disorders or cancer, but some are beneficial and lead to evolution or traits in polyploid plants. Examples of genetic disorders and polyploid crops are also provided.
12-3
The DNA base code that codes for the amino acid recognized by the tRNA with the anticodon UAC would be TAC. This is because:
- The tRNA anticodon UAC pairs with the mRNA codon AUG
- In DNA, T pairs with A and A pairs with U
- Therefore, the complementary DNA sequence that would code for the mRNA codon AUG is TAC.
So the DNA base code for the amino acid recognized by the tRNA with anticodon UAC is TAC.
12-2
The document summarizes DNA replication in prokaryotic and eukaryotic cells. In prokaryotes, DNA replication begins at a single point and proceeds bidirectionally along the circular chromosome. In eukaryotes, replication begins at many sites and also proceeds bidirectionally along the linear chromosomes, which are packaged into nucleosomes and further condensed into chromatin. The semi-conservative model of replication is described, in which the parental DNA strands separate and each serves as a template for a new complementary strand.
12 1
Griffith's transformation experiments showed that a component from dead S strain bacteria could transform live R strain bacteria to the S strain, causing disease. Avery later showed that the transforming factor was DNA. Hershey and Chase's experiment, using radioactive labeling of bacteriophage DNA and protein, demonstrated that DNA, not protein, entered the bacterial cell and was responsible for heredity transfer. Together, these experiments provided strong evidence that DNA is the genetic material.

Meiosis produces gametes through two rounds of cell division beginning with one diploid cell and ending with four haploid cells. In meiosis I, homologous chromosomes pair and separate, reducing the chromosome number by half. Meiosis II separates sister chromatids, further dividing the cell and its genetic material. The steps of crossing over and independent assortment in meiosis I contribute to genetic variation among gametes and offspring.
11 3
This document discusses several genetic inheritance patterns beyond simple dominance and recessiveness:
1) Codominance - Both alleles contribute to the phenotype, such as a cow that is both red and white producing a roan coat color.
2) Multiple alleles - A single gene can have more than two alleles influencing a trait, such as four alleles determining rabbit coat color.
3) Sex linkage - Some traits are determined by genes on the X chromosome, making them more common in one sex, like color blindness being more prevalent in males.
11 1 2012-h
DNA is copied when mitosis or meiosis begins, forming new cells with identical or varying chromosomes. Gregor Mendel conducted experiments with pea plants in the mid-1800s and discovered that traits are inherited as discrete units called factors, now known as genes, which segregate independently during gamete formation according to his laws of inheritance. His work established the foundations of classical genetics.
11 5 linkage
1) Gene linkage refers to genes that are located on the same chromosome and are usually inherited together into the same gametes. It is the chromosomes, not individual genes, that assort independently.
2) Linked genes may separate into different gametes during crossing over, which occurs more frequently between genes that are farther apart on the same chromosome.
3) A gene map shows the relative locations of known genes on a chromosome but not their exact positions.

Editor's Notes
- Dolly (5 July 1996 – 14 February 2003) was a female domestic sheep , and the first mammal to be cloned from an adult somatic cell , using the process of nuclear transfer . The production of Dolly showed that genes in the nucleus of such a mature differentiated somatic cell are still capable of reverting back to an embryonic totipotent state
