DNA contains the genetic code that determines an organism's traits. It is found in nearly every cell and carries the instructions for making proteins. These proteins determine each cell's function and are inherited from parents, allowing traits to be passed down. DNA encodes genes which contain the instructions for building specific proteins. Together, genes and proteins determine an individual's characteristics and allow life itself.

Dna and genes
DNA contains the genetic code that determines an organism's traits. It is made up of nucleotides with four bases (A, T, G, C) that pair up in a double helix structure. Genes, located on chromosomes, are segments of DNA that encode instructions for making proteins. DNA is passed from parents to offspring through sexual reproduction, which involves the fusion of egg and sperm cells to form a new individual with a random combination of the parents' genes. Mutations can occur in DNA and be inherited, sometimes causing genetic disorders.
Molecular biology
Molecular biology is a branch of science concerning biological activity at the molecular level.
The field of molecular biology overlaps with biology and chemistry and in particular, genetics and biochemistry.
A key area of molecular biology concerns understanding how various cellular systems interact in terms of the way DNA, RNA and protein synthesis function.
Molecular biology is the study of molecular underpinnings of the process of replication, transcription and translation of the genetic material.
Genetic Material
The genetic material of a cell or an organism refers to those materials found in the nucleus, mitochondria and cytoplasm, which play a fundamental role in determining the structure and nature of cell substances, and capable of self-propagating and variation.

Biotechnology Chapter Four Lecture- DNA
This document provides an introduction to studying DNA. It describes the structure and function of DNA, including the double helix structure formed by base pairing between nucleotides. It also differentiates between prokaryotic and eukaryotic DNA structure and regulation. Key aspects covered include DNA replication, bacterial culture techniques, plasmid vectors, operon regulation in prokaryotes, and gene expression in eukaryotes. The learning outcomes focus on understanding DNA structure and function, differences between prokaryotic and eukaryotic systems, viral applications in genetic engineering, and gel electrophoresis techniques.
Unit 1 genetics nucleic acids dna
This document provides information on genetics and DNA. It discusses that DNA is found coiled in chromatin in the nucleus of cells. During cell division, chromatin coils tightly to form chromosomes which are duplicated so each new cell contains a full set. DNA is made of nucleotides containing a sugar, phosphate, and one of four nitrogenous bases. The bases bond with each other to form the sides of the DNA double helix structure. Experiments by Griffith, Hershey and Chase provided evidence that DNA is the genetic material. Watson and Crick used evidence from Franklin and others to develop the first model of the DNA double helix structure. DNA holds the instructions for development and reproduction and can replicate itself through semiconservative replication.
Genes and DNA
Genes and DNA molecules carry the genetic code that controls what cells are made of and what they do. DNA is made up of a double helix structure with base pairs that always pair together in the same way - A pairs with T and C pairs with G. DNA can make copies of itself through a process called replication where the DNA helix unzips and each single strand builds a new double strand, allowing genetic information to be passed on to new cells.

DNA: A Short Lesson
DNA, or deoxyribonucleic acid, is the hereditary material found in nearly every cell of humans and other organisms. It contains genetic instructions that are stored as a code made up of four chemical bases and is capable of replicating itself. DNA is typically located in the cell nucleus but a small amount can also be found in mitochondria. It contains the genetic instructions necessary for life.
D.n.a.
DNA replication is the process by which a cell makes an identical copy of its DNA before cell division. It is essential for reproduction as it allows the transfer of genetic traits from parents to offspring. During DNA replication, the double-stranded DNA molecule unwinds and each strand acts as a template to produce a new complementary strand. This results in two identical DNA molecules containing the same genetic information as the original DNA.
Edexcel GCSE Biology | 1) DNA
DNA contains genes that code for proteins and is found coiled up in chromosomes in human cells. It has a double helix structure with two strands bound by four nucleotide base pairs: adenine pairs with thymine and cytosine pairs with guanine. Franklin and Wilkins discovered DNA's helical structure by emitting X-rays at crystallized DNA and recording the patterns. Watson and Crick then used this information to construct a DNA model showing the base pairs. A hands-on experiment demonstrates DNA as a white stringy substance that can be extracted from onion cells by breaking down membranes with salt and detergent, then precipitating the DNA out of solution with alcohol.

DNA carries genetic information and consists of two strands linked by hydrogen bonds between complementary nucleotide base pairs. DNA can be cloned by inserting a foreign gene into a bacterial plasmid, which is then taken up by bacteria and replicated along with the plasmid. This results in multiple copies of the gene of interest that can be harvested and used for research or applications such as producing therapeutic proteins.

DNA carries genetic information and consists of two strands linked by hydrogen bonds between complementary nucleotide base pairs. DNA can be cloned by inserting a foreign gene into a bacterial plasmid, which is then inserted into bacteria to produce multiple copies of the gene. Gene cloning is useful for basic research and applications such as producing proteins, altering organisms, and treating diseases.
Heredity and evolution
1. Genes are pieces of DNA that contain instructions for traits and are made up of different arrangements of bases including adenine, thymine, cytosine, and guanine.
2. DNA carries hereditary information in the form of genes on structures called chromosomes in cell nuclei. It directs the synthesis of proteins through a process involving transcription of DNA into mRNA and translation of mRNA into proteins.
3. Mutations, or changes in genes, over time due to errors in DNA replication or exposure to mutagens can lead to evolution as mutations result in hereditary changes and variations between organisms that natural selection can act upon.
DNA genetic material
- Friedrich Miescher first isolated DNA in 1869 and called it "nuclein". Later scientists identified its basic components as nucleotides and its double helix structure.
- In 1953, Watson and Crick discovered that DNA has a double helix structure and is composed of nucleotides containing a sugar, phosphate, and nitrogenous base. Base pairing occurs between adenine and thymine and cytosine and guanine.
- DNA carries the genetic instructions that are passed from parents to offspring. It controls protein synthesis and regulates gene expression, which allows cells to perform specialized functions. Mutations in DNA can lead to genetic diversity and influence evolution.

This document provides information on genetics and DNA. It discusses that DNA is found coiled in chromatin in the nucleus of cells. Chromosomes contain duplicated DNA and genes. DNA is made of nucleotides containing nitrogenous bases and sugars. Watson and Crick discovered that DNA has a double helix structure with adenine bonding with thymine and guanine bonding with cytosine. DNA replicates semi-conservatively before cell division. Genes can be cloned using recombinant DNA technology or PCR to produce proteins like insulin for medical use.
How dna works
DNA contains the genetic instructions used in the development and functioning of all known living organisms. It is found in the nuclei of cells and organelles called mitochondria. DNA is made up of nucleotides containing combinations of four bases that code for the production of proteins. Genes are sections of DNA that carry these instructions. Through DNA replication, cell division, and sexual reproduction, organisms pass their genetic material to offspring. Mutations in genes can result in genetic variations that impact traits.
Gene discovery
This document discusses gene discovery and DNA structure. It defines key terms like genotype, phenotype, genes and genomes. It describes the double helix structure of DNA and how DNA is composed of nucleotides. Genes are located on chromosomes and encode proteins. DNA is transcribed into mRNA and then translated into proteins. Eukaryotic and prokaryotic genome annotation aims to find genes, exons, transcripts and predict function. DNA must replicate before cell division to produce double-stranded chromosomes from single-stranded ones.
DNA-RNA-PPT 01.pptx
DNA and RNA are the building blocks of life that work together to direct protein synthesis. DNA stores and replicates genetic information, while various types of RNA help read and translate DNA instructions. The document defines DNA and RNA, describing their structures, functions, and how they work cooperatively through processes like transcription, translation, and semi-conservative replication to create proteins. Key differences between DNA and RNA include their single vs. double-stranded nature and the presence of thymine in DNA and uracil in RNA.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

What is dna
- 1. What is D.N.A • DNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria. • DNA is in each cell in the organism and tells cells what proteins to make. A cell's proteins determine its function. DNA is inherited by children from their parents. This is why children share traits with their parents, such as skin, hair and eye colour. The DNA in a person is a combination of the DNA from each of their parents.
- 2. What D.N.A does • -DNA carr-ies all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made). Specifically, the order of nucleotides within a gene specifies the order and types of amino acids that must be put together to make a protein. • A protein is made of a long chain of chemicals called amino acids Proteins have many functions: • Enzymes that carry out chemical reactions (such as digestive enzymes) • Structural proteins that are building materials (such as collagen and nail keratin) • Transport proteins that carry substances (such as oxygen- carrying haemoglobin in blood) • Contraction proteins that cause muscles to compress (such as actin and myosin) • Storage proteins that hold on to substances (such as albumin in egg whites and iron-storing ferritin in your spleen) • Hormones - chemical messengers between cells (including insulin, estrogen, testosterone, cortical, et cetera) • Protective proteins - antibodies of the immune system, clotting proteins in blood • Toxins - poisonous substances, (such as bee venom and snake venom) • The particular sequence of amino acids in the chain is what makes one protein different from another. This sequence is encoded in the DNA where one gene encodes for one protein.
- 3. What the genetic code does • Genes are formed of DNA. DNA is a collection of chemical information that carries the instructions for making all the proteins a cell will ever need. Each gene contains a single set of instructions. These instructions usually code for a particular protein. Half of a person's genes come from the mother. The other half come from the father.
- 4. Why it’s important Because without it we would not be alive. Because the genetic information tell are cells what to be.
- 5. Uses of D.N.A • forensic science • D.N.A testing • Maternity • Finger printing
