Detailed explanation-1: -Today, this molecule is called DNA. Nearly all of the cells within a single organism include exactly the same DNA. DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T).
Detailed explanation-2: -Among biomolecules, nucleic acids, namely DNA and RNA, have the unique function of storing an organism’s genetic code-the sequence of nucleotides that determines the amino acid sequence of proteins, which are of critical importance to life on Earth.
Detailed explanation-3: -Transfer RNAs (tRNAs) Transfer RNAs, or tRNAs, are molecular “bridges” that connect mRNA codons to the amino acids they encode. One end of each tRNA has a sequence of three nucleotides called an anticodon, which can bind to specific mRNA codons. The other end of the tRNA carries the amino acid specified by the codons.
