WebbThe process of DNA replication can be summarized as follows: DNA unwinds at the origin of replication. New bases are added to the complementary parental strands. One new strand is made continuously, while the other strand is made in pieces. WebbThe third big RNA processing event that happens in your cells is RNA splicing.
