Mutation and DNA Repair
... DNA base. Replication leads to a base change: one daughter stays a C-G base pair while the other is converted to T-A. Over evolutionary time, this has led to a loss of CpG dinucleotides in human DNA. However, methylation of cytosine is associated with gene inactivation, and genes that are expressed ...
