Which one of the following codons is recognized by this tRNA?a) 5' UUC 3'b) 5' CTT 3'c) 5' CUU 3'd) 5' TTC 3'
Keith_Richards [23]

Hello. This question is incomplete. The full question is:

A tRNA anticodon is 5' GAA 3'.

Which one of the following codons is recognized by this tRNA?a) 5' UUC 3'b) 5' CTT 3'c) 5' CUU 3'd) 5' TTC 3'

Answer:

a) 5' UUC 3'

Explanation:

Anticodons are sequences of nitrogenous bases that establish complementarity with sequences of nitrogenous bases in a codon.

As you know, mRNA has the nitrogenous bases Adenine (A), cytosine (C), guanine (G) and uracil (U). In this system, guanine is supplemented with cytosine and adenine is supplemented with uracil.

These bass are organized into codons, which are a set formed by 3 of these bases.

The tRNA has the same bases, but its codons must recognize and complement the codons of the mRNA, being then called Anticodons.

In this case, if a tRNA has the anticodon 5 'GAA 3', it must bind to codons 5 'UUC 3' in the mRNA.
