Brainliestt ! 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? the cell will not make functional proteins from that mrna strand. the cell will die once it tries to use that strand of mrna. the cell will have to destroy any ribosomes that use the mrna strand. the cell will pass the mrna on to all the cells made from it.

The answer is; The cell will not make functional proteins from that mRNA strand.

The mRNA will not make a functional protein because the folding of the protein will be altered including its interactions with other proteins or substrates. Luckily, proteins and mRNA have a short half-life in the body and the biomolecules will normally be degraded after some time with functional proteins taking their place.

Functional proteins will replace them because the DNA remains the same without mutations hence other mRNA transcribed afterward will translate to functional proteins.

thymine. in rna, thymine is replace by uracil
