MCQ
Degeneration of a genetic code is attributed to the:
- AFirst member of a codon
- BSecond member of a codon
- CEntire codon
- DThird member of a codon
Explanation:
Degeneration of a genetic code is attributed to the third member of the codon. Degeneracy of codons is the redundancy of the genetic code. Degeneracy results because there are more codons than encodable amino acids. The codons encoding one amino acid may differ in any of their three positions; however, more often than not, this difference is in the second or third codon.
