The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way. During DNA replication the leading strand is replicated continuously whereas the lagging strand is replicated in segments known as Okazaki fragments.
Best Answer: I think it's because DNA needs thymine to replicate and produce daughter strands, and also protects the DNA from attack and manipulation. However RNA does not need this as it is not a part of a genomic building block ie/ all organisms are made up of DNA, so it uses uracil.
