Question

Which of the following anticodon sequence will bind to the transcribed codon 5'-ACT-3'?

• A. 3'-ACU-5'
• B. 3'-TGA-5'
• C. 3'-UGA-5'
• D. 5'-UGA-3'
• E. None of the above

Answer 1

Answer: (C)

3'-UGA-5'

The codons are present on the m-Rna and it pairs with the anticodon present on the t- Rna. Due to complementary base pairing between codons and anticodon polypeptide is synthesised. Here the transcribed codon reads

5'-ACT-3' thus, the anticodon will be UGA (as A pairs with U, C pairs with G, and U pairs with A.

Thus the correct option is C.
