Question

Originally put D, answer was wrong.

1. Let's step through the process of seeing how many codons or amino acids are possible for 5 bases with increasing codon length. Let's call the new base quartine, so we have the bases adenine, guanine, cytosine, thymine, and quartine. How many different codons (amino acids) could we specify with these 5 bases if only one base was needed to specify a codon (codon ength of 1 base)? A. 3. Codons are always read in sets of three. B. 22. There are 22 amino acids. C. 5. One for each base. D. None. Without three bases in a codon, there can't be any codons.

Explanation / Answer

We must first understand that this is a hypothetical situation where there are 5 bases in the given system. And it also mentions that one base = one codon as codon length is 1 base. Given these two pre requisites, we can produce only 5 amino acids or codons with the 5 bases present in the system.

Ans is option C. 5. One for each base.

In nature, the codon is made of triplet base where there is a possibility of different combinations therefore giving rise to a plethora of a theoretical 64 combinations (43) for 20 amino acids. But in this scenario one base - one codon rule gives us no such combinations.
