Plasmids as vectors
This document provides an overview of plasmids. It begins by noting that plasmids were first introduced by American molecular biologist Joshua Lederberg in 1952. It then discusses that recombinant DNA technology involves inserting a gene of interest into a plasmid vector. Plasmids are described as circular DNA molecules that can replicate independently of the bacterial chromosome and confer selective advantages to bacteria. The document outlines the components and functions of plasmids, including origins of replication, antibiotic resistance genes, and multiple cloning sites. It also discusses the applications of plasmids in DNA cloning, genetic engineering, and production of therapeutic proteins.

PLASMIDS AND VECTORS
Plasmid vectors like pBR322 and pUC are commonly used cloning vectors. pBR322 was one of the first vectors created and has advantages like a small size, antibiotic resistance markers, and a high copy number. pUC vectors also have a small size and high copy number, and contain a multiple cloning site within the lacZ gene allowing visual selection of recombinants. Artificial vectors combine elements from different sources to overcome limitations of natural plasmids, and are designed for efficient cloning and expression of foreign DNA in host cells.

Gene cloning allows for the creation of identical copies of genes. It involves amplifying genes using polymerase chain reaction, cutting DNA with restriction enzymes, and joining DNA fragments together with DNA ligase. Cloning vectors like plasmids and bacteriophages are used to move genes into host cells. Transformed cells are selected using antibiotic resistance or reporter genes. Cloned genes have applications in pharmaceutical production, disease diagnosis using probes or PCR, and controlling insect pests by producing bacterial pesticides, transgenic plants, or viral pesticides.
Vectors
Vectors can perform their functions in two main ways: transcription and expression. There are several types of vectors, including plasmids, which are small, self-replicating DNA molecules commonly used in molecular cloning. Plasmids are important tools in genetic engineering as they can be easily manipulated and transformed into bacteria to generate multiple copies of recombinant DNA. Common plasmid vectors include transcription vectors, which amplify DNA sequences without expressing proteins, and expression vectors, which are used to express foreign genes in cells.

1) Gene cloning involves inserting foreign DNA into a plasmid vector, transforming bacteria with the recombinant plasmid, and allowing the bacteria to replicate, producing multiple copies of the gene of interest.
2) Restriction enzymes are used to cut the DNA at specific sites, producing sticky ends that allow insertion of the gene into the plasmid.
3) Transformed bacteria containing the recombinant plasmid are selected by growing on antibiotic-containing media, with the antibiotic resistance gene on the plasmid allowing only those bacteria to survive.
Genetic Technology.pptx
This document discusses genetic engineering tools and techniques. It explains that genetic engineers use restriction enzymes, plasmids, and promoters to insert genes from one organism into another. The inserted genes are expressed to produce proteins like insulin. Gel electrophoresis and fluorescent markers are described as tools to analyze DNA and identify transformed bacteria. The overall aim is to manipulate genes between species to study and modify organisms.
DNA cloning
DNA cloning techniques allow for the reproduction of DNA fragments. There are two main approaches: cell-based cloning using living cells and in vitro cloning using PCR. The cloning process involves cutting out the gene of interest and a host plasmid with the same restriction enzyme, ligating the gene into the plasmid, transforming bacteria with the new plasmid, and selecting for transformed colonies. Common cloning vectors include plasmids, bacteriophages, cosmids, YACs, and retroviral vectors which allow incorporation of foreign DNA into host genomes. PCR cloning strategies like TA cloning take advantage of Taq polymerase adding extra adenines to PCR products, allowing ligation into vectors with thymidine overhangs.
plasmid
A plasmid is a small, circular, extrachromosomal double stranded DNA that has the capacity to replicate independently.
Discovered by Laderberg in 1952.
It naturally occur in bacteria, however sometimes present in archaea and eukaryotes.
The genes carried in plasmid benefit the survival of the organism by providing them with genetic advantages like antibiotic resistance etc. under certain situation or particular conditions.
They provide mechanism for horizontal gene transfer within a population of microbes and thus provide a selective advantage under a given environmental state.
Ge m1 3 types of vectors
Vectors are essential tools for genetic engineering that allow recombinant DNA to be introduced into and replicated in host organisms. Plasmids are the most commonly used bacterial cloning vectors. Plasmids are small, circular DNA molecules that can replicate independently of the bacterial chromosome. Important plasmid vectors include pBR322, which contains two antibiotic resistance genes for selection, and pUC19, which allows blue-white screening to identify recombinant clones through disruption of the lacZ gene. Plasmid vectors are useful for amplifying DNA inserts, producing recombinant proteins, and transferring genes for applications such as gene therapy.
Plasmids and bacteriophages
This document discusses plasmids and bacteriophages. It defines plasmids as small, extrachromosomal DNA molecules that can replicate independently of chromosomal DNA within bacterial cells. Plasmids are classified based on their transmissibility and function. Methods for purifying plasmid DNA from bacterial cells are also described. Bacteriophages are viruses that infect bacterial cells, and the document discusses the genetic organization and life cycles of important bacteriophages such as lambda. The roles of plasmids and bacteriophages in genetic engineering and molecular cloning are also summarized.
Plasmid
Plasmids are small, circular DNA molecules that are separate from the bacterial chromosome and can replicate independently. They were first described by American molecular biologist Joshua Lederberg in 1952. Plasmids often contain genes that provide bacteria with functions not necessary for survival, such as antibiotic resistance or virulence factors. They are commonly used as cloning vectors in genetic engineering to generate copies of genes of interest in bacteria. Plasmids have an origin of replication, selectable marker gene, and cloning site that allow them to be used to replicate, select for, and clone DNA fragments in bacteria.

Bacterial plasmids are small, circular pieces of DNA that are separate from the bacterial chromosome. Plasmids commonly contain genes that provide useful traits to bacteria like antibiotic resistance, but are not essential for survival. Plasmids can be transferred between bacteria through conjugation. There are different types of plasmids classified by their functions, such as fertility plasmids involved in conjugation, resistance plasmids containing antibiotic resistance genes, and virulence plasmids that can make bacteria pathogenic. Plasmids are useful in genetic engineering and cloning because they can be easily manipulated in the laboratory by inserting foreign DNA fragments using restriction enzymes and ligase. This allows bacteria to produce proteins like human insulin.

There are 5 shapes of plasmids: nicked open-circular, relaxed circular, linear, supercoiled, and supercoiled denatured. Plasmids vary in size from 1kb to several megabase pairs. Plasmids contain an origin of replication, antibiotic resistance genes, and other components like promoters. Plasmids are classified based on function into fertility, resistance, colicin, degradative, and virulence plasmids. They are also classified based on their ability to transfer into conjugative and non-conjugative plasmids. Plasmids can be isolated from bacterial cells through cell growth, centrifugation, lysis, protein and DNA separation, purification, precipitation, and storage

Biotechnology refers to the use of living organisms or their components to develop products and processes. It has applications in fields like agriculture, medicine, and industry. Modern biotechnology techniques include genetic engineering and aseptic techniques. Genetic engineering involves altering genetic material through techniques like recombinant DNA, gene transfer into host organisms, and gene cloning. It allows scientists to modify organisms for useful purposes. Restriction enzymes, vectors, DNA polymerase and ligase are important tools used in genetic engineering and recombinant DNA technology.
recombinant dna technology
Recombinant DNA technology involves the manipulation of genetic material to achieve desired goals. It works by generating DNA fragments, inserting the fragments into cloning vectors, introducing the vectors into host cells, multiplying the clones containing recombinant molecules, and expressing genes to produce desired products. Key aspects include restriction endonucleases that cut DNA at specific sites, DNA ligases that join cut fragments, and various host cells like E.coli and eukaryotic cells. Vectors like plasmids, bacteriophages, and artificial chromosomes are used to carry foreign DNA. The technology has applications in research, medicine, agriculture, and industry.
Cloning by bacterial plasmids
Plasmid vectors are circular, self-replicating DNA molecules found in bacteria cytoplasm that can transfer genes between cells. They are useful for cloning small DNA fragments under 10kb due to their small size and selection strategies. However, plasmids are less useful for cloning large fragments over 10kb. Plasmid vectors for cloning contain an origin of replication for independent replication, selective markers for identifying cells containing the plasmid, and a multiple cloning site to insert DNA fragments.
Recombinant dna
Recombinant DNA (rDNA) refers to DNA created outside living cells by joining DNA from multiple sources. Common techniques for creating rDNA include restriction enzymes to cut DNA strands, ligation to join strands, and transformation or transfection to introduce rDNA into host cells. Vectors like plasmids, viruses, and artificial chromosomes are often used to replicate and express rDNA in host cells. rDNA techniques have applications in gene cloning, DNA sequencing, genetic engineering of plants and animals, and gene therapy to treat diseases.

Here is a summary of Pneumothorax:
Pneumothorax, also known as a collapsed lung, is a condition that occurs when air leaks into the space between the lung and chest wall. This air buildup puts pressure on the lung, preventing it from expanding fully when you breathe. A pneumothorax can cause a complete or partial collapse of the lung.
