Question

while mRNA strands are being created, a sequence is sometimes miscopied. what is the worst that could happen to a cell should this take place?
a the cell will die once it tries to use that strand of mRNA
b. the cell will have to destroy any ribosomes that use the mRNA strand
c. the cell will not make functional proteins from that mRNA strand
d. the cell will pass the mRNA on to all the cells made from it

Answer 1

n most the case cell wont make the functional proteins from the mRNA strand. we do have some regulatory protein which degrades the protein produced by mutational effect.

the cell wont die as soon as it use the mRNA strand . it depends, cells have varies mechanisms to stop the expression of the protein before reaching its destination.
mostly cell wont die instead it wont able to perform its function like before.

if the protein is so vital for the cell survival then the cell may die.
