Question

What is the function of the start codon of an mRNA sequence?

A. The start codon acts as a checkpoint in the eukaryotic cell cycle.
B. The start codon protects the mRNA from being degraded.
C. The start codon signals for the ribosome to begin assembling amino acids at that point in the mRNA sequence.
D. The start codon signals for the ribosome to release the mRNA sequence.

Answer 1

Option no. C is the correct answer.

The start codon signals for the ribosome to begin assembling amino acids at that point in the mRNA sequence.

Answer 2

Option (C).

Step-by-step explanation:

Codons represent triplets of nucleotides in DNA or mRNA that provide information for the process of protein synthesis. The first codon in mRNA transcript is known as start codon.

Start codon provides initiation signals for the ribosomes to start the process of translation, during which formation of polypeptide chain takes place.

Thus, the correct answer is option (C).
