While the dna in a human skin cell was being replicated, a single base was miscopied. what will be the most likely result of this for the cell in which it happened? all the proteins the cell creates from the miscopied strand will do different jobs than the old ones. if the new sequence codes for the same amino acid as the original cell, it will function normally. both new dna strands will end up together in a new cell, and the inaccurate one will be discarded. any miscopied dna will be replaced with an accurate dna copy once the cell divides.

the most likely result is If the new sequence codes for the same amino acid as the original cell, it will function normally.

For the first proposition, it can be false if the mismatch occurs at the level of the gene's intron (the part that will not be translated into proteins).

For the third proposition, it is false because each daughter cell will have a new strand and an original strand (the replication is semi conservative).

For the fourth one, it is wrong because normally the repair of mismatches is programmed during or just after replication, but not after cell division.
