Discussion of all aspects of biological molecules, biochemical processes and laboratory procedures in the field.
Hi....A couple of questions..help....
If a structural gene contains 300 DNA nucleotides, how many amino acids will be used in the protein synthesis process?
If a protein has 150 amino acids, how many DNA nucleotides would make up the structural gene?
No of amino acids= 300/3 = 100 amino acids
No of nucleotides= 150*3 = 450 nucleotides
if we don't go in details(stop codon...)?
I think if you really want to count stop codons (start codons are transcribed) you get these results
(300 nt - 1 non transcribed stop codon)= 99 aa
and (150aa + 1 non transcribed stop codon)x3= 453nt
From what i know, start codons are transcripted, but if your protein does not begin with metionin then it is later removed

r we forgetting something...
if the structural gene contains introns then the no. of aa reqd. for protein making is indeterminate !
or else if its a bacterial gene then my predecessors have already done the math.
