Answer 1

Discuss the role of enzyme DNA ligase plays during DNA replication. ... However, it is discontinous at a lagging strand in the form of DNA segments. These DNA segments are known as Okazaki fragments. These fragments are later joined with the help of the enzymes DNA ligase. DNA base pairing, the base pairs are adenine-thymine and guanine-cytosine. ... If double stranded DNA has 14% G (guanine), what percent A (adenine), T (thymine) and C (cytosine) would you expect? ... If a sample of DNA has 15% Adenine, then what percentage of cytosine does it have?
