Question

question 88
the anticodon of a particular trna molecule is...
○ complementary to the corresponding mrna codon.
○ complementary to the corresponding triplet in rrna.
○ the part of trna that bonds to a specific amino acid.
○ catalytic, making the trna a ribozyme.

Explanation:

To solve this, we analyze each option:

• Option 1: tRNA's anticodon pairs with mRNA codon via base - pairing (A - U, C - G), so it's complementary to mRNA codon.
• Option 2: rRNA is part of ribosome, anticodon doesn't pair with rRNA triplet.
• Option 3: The 3' end of tRNA (not anticodon) bonds to amino acid.
• Option 4: tRNA isn't a ribozyme (ribozymes are catalytic RNA, tRNA has no catalytic activity).

Answer:

A. complementary to the corresponding mRNA codon.
