tRNA is also called the 'adapter molecule' because it:
AAdapts the cell membrane to ribosomes
BAdapts DNA into RNA
CCarries information from DNA to ribosome
DReads the codon on mRNA via its anticodon AND carries the corresponding amino acid — linking the two languages of nucleic acid and protein
Answer & Solution
Correct answer: D. Reads the codon on mRNA via its anticodon AND carries the corresponding amino acid — linking the two languages of nucleic acid and protein
**tRNA** (cloverleaf 2D, inverted-L 3D) has an **anticodon** at one loop (base-pairs with codon on mRNA) and an **amino acid acceptor end (3′ CCA)** at the other — physically linking codon to amino acid. There's a special **initiator tRNA** for AUG and **no tRNA for stop codons** (releases factors instead).
