What is DNA in biology simple?

The molecule inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.

What is DNA short answer 10?

DNA is the genetic material which carries all the hereditary information. Genes are the small segments of DNA, consisting mostly of 250 – 2 million base pairs. A gene code for a polypeptide molecule, where three nitrogenous bases sequence stands for one amino acid.

What is DNA Class 9 short answer?

Answer. Answer: Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.Apr 17, 2020

What is DNA answer for kids?

DNA is a short nickname for deoxyribonucleic (say: dee-OK-see-ri-bo-new-klee-ik) acid. DNA is the genetic information inside the cells of the body that helps make people who they are. It’s the instructions for how to make the body, like the code to a video game or blueprints for a house.

Where is the DNA?

DNA is packed tightly in the nucleus of your cells as chromosomes. A chromosome is a thread-like structure that has DNA coiled around proteins called histones. Humans are ‘diploid’ organisms, which means they have two copies of each chromosome—one from mom and one from dad.

What is DNA in topper?

DNA stands for ‘deoxyribonucleic acid‘ and it is the hereditary material in humans and most other organisms. The correct structure of DNA was first worked out by Watson and Crick in 1953.

What is your DNA?

Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.Aug 24, 2020

What is DNA in BYJU’s?

DNA (Deoxyribonucleic acid) RNA (Ribonucleic acid)
The function of DNA is the transmission of genetic information. It acts as a medium for long-term storage. RNA is critical for the transmission of the genetic code that is necessary for protein creation from the nucleus to the ribosome.

What is DNA by Brainly?

Brainly User. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.May 13, 2020

What is DNA definition Class 11?

Hint: DNA is a double helix structure that is formed by the base pairs attached to a sugar-phosphate backbone. There are four chemical bases i.e. adenine, guanine, cytosine and thymine. Complete answer: The full form of DNA is deoxyribonucleic acid and is the hereditary material in humans and in all other organisms.

Who discovered DNA?

Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.

What is DNA High School?

But what is dna made up of dna is made up of lots of molecules called nucleotides dna is a polymerMoreBut what is dna made up of dna is made up of lots of molecules called nucleotides dna is a polymer because it is a large molecule composed of repeated subunits.

What is RNA short answer?

Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA.

What is DNA made out of?

DNA is made up of a chain of molecules called Nucleotides. Each nucleotide contains a nitrogen base, a sugar group and a phosphate group. Four possible nitrogen bases can be present in DNA; Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). Human DNA contains billions of DNA bases.Jun 11, 2020

What is DNA and its function?

Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.Aug 24, 2020

What is DNA made up of for kids?

DNA is a long thin molecule made up of something called nucleotides. There are four different types of nucleotides: adenine, thymine, cytosine, and guanine.

What is DNA high school biology?

DNA stands for “deoxyribonucleic acid.” The backbone of DNA is comprised of alternating sugar and phosphate units, in which the sugar is deoxyribose. The backbone of RNA is also comprised of sugar and phosphate units, but uses the sugar ribose.

What is the main function of DNA?

DNA is responsible for carrying and transmitting hereditary materials or genetic instructions from parents to offspring. In addition to ensuring that all living things pass on their genetic information, DNA is essential for the synthesis of proteins.

Who discovered DNA?

Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.

What is DNA and How Does it Work?

What DNA contains?

DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and a nitrogen base.Mar 25, 2021

DNA- Structure and function of Deoxyribonucleic Acid (DNA)

Where does DNA come from?

Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.

What is RNA short answer?

Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA.

How long is our DNA?

The average length of a human nucleotide is 0.6 nanometers, or 0.0000000006 meters, so human DNA is about 1.8 meters (5 feet) long.Jun 7, 2002

Who discovered DNA for kids?

Rosalind Franklin (1920–1958) was an English scientist who made X-ray images of DNA. It was a very important part of the research that led to the discovery of the structure of DNA, which is a spiral shape. DNA is the information in our body that our body uses to build cells.

When was DNA discovered?

The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA), by James Watson and Francis Crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within …

What is RNA for kids?

RNA is a copy, or a transcription, of DNA. See, the DNA is very important, since it holds the information needed for making new cells and maintaining life, so it never leaves the nucleus. The RNA is the one that goes out to do work throughout the cell.Dec 6, 2021
