Detailed explanation-1: -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.
Detailed explanation-2: -DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base-A, C, T, or G-can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.
Detailed explanation-3: -DNA is important in terms of heredity. It packs in all the genetic information and passes it on to the next generation. The basis for this lies in the fact that DNA makes genes and genes make chromosomes. Humans have 23 pairs of chromosomes – a total of 46 chromosomes.
Detailed explanation-4: -DNA (or deoxyribonucleic acid) is a long molecule that contains our unique genetic code. Like a recipe book, it holds the instructions for making all the proteins in our bodies.
