MCQ
What is the main function of $tRNA$ in relation to protein synthesis?
  • A
    Initiates transcription
  • B
    Inhibits protein synthesis.
  • ✓
    Identifies amino acids and transport them to ribosomes.
  • D
    proof reading.
✓

Answer

Correct option: C.
Identifies amino acids and transport them to ribosomes.
c
$tRNA$ (or transfer $RNA$) is a single stranded $RNA$ molecule which brings amino acid and reads the genetic code in the process of transcription. It helps decode a messenger $RNA$ $(mRNA)$ sequence into a protein. It functions at specific sites in the ribosome during translation, which is a process that synthesizes a protein from a $mRNA$ molecule.
