Neucleotides - biology help!!!?

Question

A transcription unit that is 8,000 nucleotides long may use 1,200 nucleotides to make a protein consisting of approximately 400 amino acids. This is best explained by the fact that

a. nucleotides break off and are lost during the transcription process.

b. there is redundancy and ambiguity in the genetic code.

c. there are termination exons near the beginning of mRNA.

d. many nucleotides are needed to code for each amino acid.

e.many noncoding stretches of nucleotides are present in mRNA.

Answer 1

E

3 nucleotides will code for 1 amino acid...so  

1200 nucleotides will code for 400 amino acids.  

Given that the transcription unit is so much more than 1200, my vote is that "e" is correct: many non coding stretches of nucleotides present in th mRNA.

Answer 2

i think d. because the protain that is created is used as a code.

that's all i know ... i hope i helped you.

Answer 3

e.
