What is a short definition of DNA?
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
What is the scientific definition of DNA?
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. Also called deoxyribonucleic acid. …
What does DNA do short answer?
What does DNA do? DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Which is the best definition of DNA?
DNA: Deoxyribonucleic acid. One of two types of molecules that encode genetic information. (The other is RNA. In humans DNA is the genetic material; RNA is transcribed from it. In some other organisms, RNA is the genetic material and, in reverse fashion, the DNA is transcribed from it.)
What are DNA bases called?
ACGT is an acronym for the four types of bases found in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). A DNA molecule consists of two strands wound around each other, with each strand held together by bonds between the bases. Adenine pairs with thymine, and cytosine pairs with guanine.
What is DNA 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.
What is DNA by Brainly?
DNA stands for Deoxyribonucleic acid. Explanation. Deoxyribonucleic acid is a molecule made up of two polynucleotide chains that spin together to form a double helix carrying genetic instructions for all known organisms and viruses to evolve, survive, mature, and reproduce. Nucleic acids are DNA and ribonuclear acid.
What is a DNA quizlet?
DNA (definition) Deoxyribonucleic Acid; A nucleic acid found in the nucleus of all living cells, which carries the organism’s hereditary information.
Why is it called DNA?
DNA, or deoxyribonucleic acid, is the central information storage system of most animals and plants, and even some viruses. The name comes from its structure, which is a sugar and phosphate backbone which have bases sticking out from it–so-called bases.
What is DNA and its function?
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.
What is the DNA function?
DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.
