Question

does amino acids have more than one codon

Answer 1

does amino acids have more then one codon

Answer 2

Let me sort of...rephrase the question.
Because this is what I think it's asking:

"Can some amino acids be made with more than one type of codon?"

Take a look at this amino acid chart:

It's really easy to read this chart.

Take a look at the VERY FIRST yellow square,
in the TOP LEFT corner of the chart.

I'm looking at two different codons, here:

(U U U) and (U U C).

Do you see how UUU and UUC are both grouped together by (Phe)?

Phe (phenylalanine) is an AMINO ACID.

UUU and UUC are the two codons that can make (Phe).

That means that (Phe) can be made by two different codons.
Either (U U U)....OR....(U U C).

If you take a look at other places, around the chart,
you can see that some amino acids can be made by more than one codon.

So, let's look at the question:
"Do amino acids have more than one codon?"

The answer's pretty obvious, yes?

Answer 3

sure....wobble hypothesis explains this and refer the codon chart
