Which of the following best describes the process of transcription during protein synthesis?
a. to pair trna with mrna
b. to deliver amino acids to the nucleus
c. to produce anticodons that will be delivered to the ribosome
d. to make an rna copy of a gene's dna sequence

The answer is 'D'. Transcription is the process by which a single stranded mRNA is formed from the double stranded DNA.

Explanation:

The central machinery of biology involves three processes- replication, transcription and translation. The process by which DNA doubles itself is called replication. In translation, protein is formed from the messenger RNA or mRNA. The major steps involved in transcription are:

In the process of translation, amino acids bind together in the ribosome to form a polypeptide chain.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
