While mrna strands are being created a sequence is sometimes miscopied. what will be the effect of this on the cell?

a. the damaged mrna may cause cell death. incorrect
b. translation may not take place.
c. future transcription will not take place.
d. ribosomes may be destroyed.

i thought it was a, but again it was incorrect, can someone me find the correct answer and the reasoning behind it.

b. Translation may not take place.

Explanation:

DNA transcription into RNA is the starting point for all phenotypic expression. As in replication, access to DNA is mediated by the interaction between proteins and certain regions strategically placed in relation to the segment to be transcribed; and it also requires helicases that denature the double strand to allow the "reading" of the nucleotide sequence by polymerases. But RNA polymerases, enzymes that perform transcription, use only one of the DNA strands as a template, allowing them to pair again at the end of the process; therefore, the end product of the transcription, or primary transcript, is a single-stranded messenger RNA molecule.

Although it is rare, messenger RNA can have errors. These errors are less harmful than the errors that occur in DNA, but they can prevent the translation from occurring later.
