One of the parental strands of DNA is 5’ ACCTCATCG 3’. The Boldface C was deaminated.

a) Predict the double stranded sequence of both daughter molecules after one round of replication.

b) Predict the double stranded sequence of all daughter molecules after two rounds of replication.

Answer #1

Answer. Deamination is the process by which amino group is removed from the bases as in the given case C is deaminated then it become the uracil so when replication starts it will pair with A instead of G. Replication is the process by which DNA double, and replication result is given in picture. As your question do not contain any boldface C. So I m taking third base C as boldface C .as you know it that A pairs with T and C pairs with G . Replication occurs in direction 5'- 3'
