Question

Consider the following sequence on mRNA AUGGCAGUGCCA. assuming that genetic code is overlap then how many number of codon may be present on this genetic code
Ans is 10
How and why?

Answer 1

Answer:If genetic code is overlapping it means that nucleobases from previous codon can be a part of next codon. In the sequence there are10 possible codons.

Answer 2

Answer:

The correct answer is 10.

Explanation:

It is said to assume that there is a codon overlap. This means that the nucleotide that is already considered in the previous triplet codon can be considered again. But codons cannot be jumped as this is beyond genetic science.

So, this leads to the 10 possible codons which are :

1. AUG
2. UGG
3. GGC
4. GCA
5. CAG
6. AGU
7. GUG
8. UGC
9. GCC
10. CCA.

This phenomenon is not seen often.
