Detailed explanation-1: -Proteins are the key working molecules and building blocks in all cells. They are produced in a similar two-step process in all organisms called protein synthesis – DNA is first transcribed into RNA, then RNA is translated into protein.
Detailed explanation-2: -Listen to pronunciation. (KOH-don) A sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid. Certain codons signal the start or end of translation.
Detailed explanation-3: -A nucleic acid sequence, the messenger RNA or mRNA, is translated into the protein it encodes by means of transfer RNAs interacting with the ribosomal apparatus. Transfer RNAs bind to three nucleotides at a time and thus divide the nucleic acid sequence into triplet codons, each specifying one amino acid.
Detailed explanation-4: -Therefore specific protein production will be related to option B, which is nucleotide sequence of the DNA. So option B is the correct answer.
