Question

In a genetic engineering experiment a piece of double-stranded DNA containing 6000 nucleotides coding for a specific polypeptide is transcribed and translated.

What is the total number of amino acids in this polypeptide?

Answer 1

hmmm....2000?

Answer 2

no

Answer 3

cuz 3 nucleotides = 1codon=1amino acid

Answer 4

answer is 1000 but why

Answer 5

@Natshane how ah?

Answer 6

I got 100 :(

Answer 7

ahh! I think I found it!

double stranded = 6000 nucleotides
One strand is coded into mRNA so 6000/2 = 3000 nucleotides
3 nucleotide = 1 codon = 1 amino acid
3000/3 = 1000 amino acids!

Answer 8

Thank:)

Answer 9

no problem :)
