Question 8

PROBLEM
Consider a stretch of DNA (a hypothetical gene) that has the sequence TACGATAGTACCAGGATT on the strand that will be transcribed.
-Now,our hypothetical gene has undergone a mutation.The mutant sequence is TACGATAGTACCAGTATT.Transcribe the mutant sequence into mRNA,and determine the amino acid sequence of the resulting polypeptide chain.Determine if the mutation produced a different amino acid sequence in the protein.What do you think the consequence of this mutation would be in terms of protein function?

Accepted Answer

The mRNA would read AUGCUAUCAUGGUCAUAA.T
