The DNA is significant molecules to undergo transcription to produce mRNA further mRNA under goes translation to produce proteins.
All enzymes are proteins. Therefore, DNA transcription rate determines the rate of protein production or enzyme synthesis.
Thus, the options (a), (c) and (b) are incorrect.
All enzymes are proteins. Therefore, DNA transcription rate determines the rate of protein production or enzyme synthesis.
Therefore, the correct option is – d. it controls the synthesis of enzymes.
