Question

Which one of the following is not true of the genetic code?

• A. Changes in the universal genetic code have occurred in some species
• B. Modifications in the anticodon do not affect the pattern of wobble pairing
• C. Some of the codons cause termination of translation
• D. In Euplotes crassus, UGA codon specifies both selenocysteine and cysteine

Hint:

The wobble hypothesis, proposed by Francis Crick, states that the base at the 5' end of the anticodon is less spatially constrained, allowing for non-standard base pairing.

Answer 1

The Correct Option is B
