If a protein contains 80 amino acids, it's corresponding gen must contain at least how many nucleotides?

A. 40
B. 120
C. 240
D. 360
E. 480


i would say C. tell me if im correct and then i'll explain it

Yes you are correct..please explain..by the way you r correct to both answers..thanks


there are 3 nucleotides in 1 codon and 1 codon that specifies one amino acid. so if there are 80 amino acids, you multiply those 80 amino acids by 3 nucleotides/per amino acid which gives you 3*80=240.
 
I agree that C is the best answer, albeit not necessarily the correct answer.
 
bicarbonate ions happen to make up 68% of the form of carbon dioxide in the blood and theres not explaining that. thats just the way it is and i remember it from my biochemistry course.

yep C is the best. I'm sure the DAT would not delve into introns and exons so just understand 3 codons for 1 amino acid

Thanks...


your very welcome 🙂 and remember dont stress too much. people tend to forget more when they are stressed or freaking out. relax and go on that beer.. i mean coffee break if you have to 😀

C is correct because you should not include anything that comes after the 80th amino acid (for ex. stop codon..or other nucleotides that prevents the mRNA from degradation). The problem is JUST talking about only the 80 AA
