Sometimes, chemical damage to dna can occur just before dna replication begins, not giving the repair system enough time to correct the error before the dna is duplicated. this gives rise to mutation. if the cytosine in the sequence tcat is deaminated and not repaired, which of the following is the point mutation you would observe after this segment has undergone two rounds of dna replication?

1)ttat
2)tuat
3)tgat
4)taat
