Question

Which of the following is utilized by all living organisms?

• A. $C{O}_2$
• B. A triplet genetic code to produce proteins
• C. Oxygen
• D. ADP as cellular energy
• E. Membrane-bound organelles

Answer 1

The correct option is B A triplet genetic code to produce proteins

The relationship between the nucleotide triplets and the amino acids is called a genetic code. This determines the sequence of amino acids in the proteins that are synthesized. The genetic code is non-ambiguous, universal and a triplet code. The genetic code is universal and is the set of rules by which information encoded within the genetic material, i.e., the DNA or mRNA sequences, are translated into proteins by living cells. The genetic code is highly similar among all organisms and can be expressed in a simple table with 64 entries. Thus, the correct answer is option B.
