Question

While mRNA strands are being created a sequence is sometimes miscopied. What is the best possible outcome for the cell should this take place?
Answer
1.The miscopied sequence codes for the same amino acids as the original sequence.
2.The mRNA will only be used to create non-critical proteins for the cell.
3.The new sequence creates a protein that serves a different function from the original.
4.The ribosomes will correct the mistake before the tRNA matches an amino acid to it.

Answer 1

@C.A.M plz help?

Answer 2

number 3

Answer 3

C.A.M, why do you think it is number three?

I think it is number one, because if the new codon codes for the same amino acid as would have been in the original protein, the new protein will be exactly the same as the old one. So it should be able to do its job with no harm, change or detriment to the cell.

Answer 4

i thought it was 3 because of the way it is the are different am i wrong

Answer 5

But if the new protein serves a new purpose in the cell - the function served by the original protein, which the cell needed to survive, won't happen. And if the new function conferred by the new protein is harmful to the cell - such as enabling it to undergo cell division when it shouldn't, thus causing cancer - then things are no good at all...

oh ok now i understand thanks
