Question

What is the full form of DNA?

Answer 1

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. DNA is located in the nucleus of the cell and it is called as nuclear DNA but a small amount of DNA can also be found in mitochondria where it is called as mitochondrial DNA. Mitochondria are structures that present in cells and convert the energy from food into a form that cells can use.
The information in DNA is stored as a code which is made up of adenine(A), guanine(G), thymine(T), and cytosine(C). Human DNA consists of about 3 billion bases and 99% of those bases are the same in all human beings. The sequence of these bases helps in determining the information available for maintaining and balancing an organism.
The important property of DNA is that they can replicate or in other words, they can make a copy of themselves. Each strand of DNA in the double helix structure can serve as a pattern for duplicating the order of the bases.

Note:DNA is a double helix structure in which nucleotides are arranged in these double helix strands. This structure is somewhat like a ladder in which the sugar and phosphate molecules form vertical side pieces of ladder.
