Detailed explanation-1: -Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.
Detailed explanation-2: -The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
Detailed explanation-3: -In living organisms, the genome is stored in long molecules of DNA called chromosomes. Small sections of DNA, called genes, code for the RNA and protein molecules required by the organism. In eukaryotes, each cell’s genome is contained within a membrane-bound structure called the nucleus.
Detailed explanation-4: -The molecule inside cells that contains the genetic information responsible for the development and function of an organism.
