Which of the following is not a property of the genetic code?
Correct answer: B. Ambiguous
- A. Non-overlapping
- B. Ambiguous
- C. Degeneracy
- D. Universal
Explanation
The genetic code is non-ambiguous. A non ambiguous code means that there is no ambiguity about a particular code. One codon specifies only one amino acid and not any other. There are 64 codons. Out of 64, 3 are stop codons or nonsense codons, i.e., these do not code for any amino acid, and the rest of the 61 codes for one of the 20 amino acids. Neither of them codes for more than one amino acid, except for GUG, which normally codes for valine, but in certain conditions, it also codes for N-formyl methionine as the initiation codon.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
