Question

After determining that the genetic code is read in triplet codons, the question arose as to whether the code was overlapping or nonoverlapping. If the code was overlapping, a change in one nucleotide could result in a change in how many amino acids?

A) 1

B) 2

C)3

D)5

Which one of the following nucleotides does NOT form a wobble pair with inosine?

A) A

B)G

C) C

D) U

Given the wobble rules, what is the fewest number of tRNAs necessary to insert the amino acid Ile, and what is the anticodon for each tRNA? There are three codons that specify Ile: AUU, AUC, AUA.

A) one, with anticodon IAU

B) one, with anticodon CAU

C)two, with anticodons IAU and CAU

D) two, with anticodons UAI and CAU

E) three, with anticodons AAU, UAG, and UAU

Explanation / Answer

Ans:

The genetic code is read in triplet codons.If the code was overlapping,a change in one nucleotide result in a change in

2 amino acids.Generally genetic code is non overlapping.
