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.

no. 1 is right. ribosomes can't do anything to the mRNA.

i go for 3 becoz just luk this codon
TUUAGU this is the original and u know it always in triplet TUU AGU(imaginary codons) but if smthng is miscopied the codon will become TTUUAGU TTU UAG  do u see the sequesnce changes..

I like 1. Redundancy of the genetic code is the best possible outcome.

anonymous · Answer

remember: we are not talking about changing the genetic code here!

and to add this: the probability of the protein having a complete new function with one amino acid changed is so low that I can't think of any example. since most proteins consist of smaller modules that contribute certain functions to said protein, a rearrangement on the chromosome is way more likely to cause a change of function. this is why I suggested my answer.
