NEET BIOLOGY

Detailed explanation-1: -Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism.

Detailed explanation-2: -Genetic instability observed in disease is termed an “expansion mutation” when the mutation is an increase in the copy number of a repeated unit, commonly a di-or trinucleotide. While the expansion mutation is well characterized in disease, the mechanism by which expansion occurs is not clear.

Detailed explanation-3: -The molecules inside cells that carry genetic information and pass it from one generation to the next. Also called DNA.

Detailed explanation-4: -Solution : Deoxyribonucleic acid.

Detailed explanation-5: -Each gene’s code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T)-in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a protein.
