Question

For efficient translation process, mRNA must have these:

• A. Small unit, Amino Acids, Release factor
• B. Start codon, Stop codon, Codes for polypeptide, UTR
• C. Promoter, Operator, Repressor
• D. Small unit, Large unit, Promoter

Hint:

The UTRs, while not coding for proteins, play crucial roles in the regulation of gene expression and mRNA stability.

Answer 1

The Correct Option is B

Efficient translation of mRNA into proteins requires several critical elements:
Start Codon (AUG): Signals the ribosome where to begin translation.
Stop Codon (UAA, UAG, UGA): Indicates where translation should end.
Coding Sequence: Specifies the sequence of amino acids in the protein.
Untranslated Regions (UTRs): Located at both ends of the mRNA, these regions help regulate translation and stabilize mRNA.
