Question

If a sequence has the initiator codon AUG, which codes for methionine, then:
Statement I: Yes, the translation process starts with methionine (AUG is the universal start codon)
Statement II: Methionine may or may not be present in the final protein, as it can be cleaved during post-translational modifications.

• A. Only Statement I is true
• B. Only Statement II is true
• C. Both statements are true
• D. Both statements are false

Hint:

AUG is the universal start codon for protein synthesis.

Answer 1

The Correct Option is C

AUG is the universal start codon in mRNA translation, marking the beginning of protein synthesis. However, methionine may be removed later during post-translational modifications.
