Answer : The correct answer is -

A. DNA.

DNA (deoxyribonucleic acid) is the nucleic acid that provides the master code for protein synthesis. It possesses the genetic instruction for protein formation in the form of codons (sequence of three nucleotides that code for particular amino acid).

It is considered as the genetic material of life forms and also passed from parents to their offspring.

DNA is transcribed to synthesise mRNA (messenger RNA), which is then converted into specific protein

by a process, called translation.

Thus, option A) is the right answer.

DNA is the nucleic acid which provides the master code for protein synthesis. Proteins are made up of 20 amino acids all coded by DNA! DNA makes up who you are.
