Changed the first triplet from ctt to ctc

Q1. All living cells, both prokaryotic and eukaryotic, have the cell structures: plasma membrane, cytosol, ribosomes, and at least one chromosome. Select any one of these. Describe its basic structure (including molecular composition) as well as the function. Explain why a cell could not exist without the function(s) performed by this cell structure.

Q2. If there was mutation in a dna triplet that changed the first triplet from ctt to ctc, would that cause the problem with the resulting polypeptide?
