Giving Everything!!!PLzzz help!!!
The process of transcription is known to have a less effective “proofing” stage to check the sequence of bases than does the process of DNA replication. What effect does this have on the base sequences produced by transcription?

A.Errors in the base sequences will result in a damaged strand of DNA.

B.The base sequences of mRNA can be exactly the same as those on DNA.


C. It is more likely that there will be more errors in coding base sequences in mRNA than there will be in DNA.

D. It is more likely that there will be fewer errors in coding base sequences in mRNA than there will be in DNA.

Answer :

Transcription produces mRNA and dna replication produces DNA. If transcription has less effective proofing it will make more errors. These errors are mutations that can affect the eventual protein produced.

Therefore C: it is more likely there will be errors in the base sequence of mRNA ( the nucleotides that make it up) than in DNA.
