WebThe process of copying the double-stranded DNA molecule is called replication. Prokaryotes replicate their DNA (the nucleoid) throughout the interval between cell divisions. In eukaryotes, the timing of replication in the nucleus is highly regulated. Article Summary: A cell must copy its DNA before it divides, so that both daughter cells have a ... WebWhen DNA is being copied, one of the two new strands of DNA at a replication fork is made continuously and is called the leading strand. The other strand is produced in many small pieces called Okazaki fragments, each of which begins with its own RNA primer, and is known as the lagging strand. (See the article on DNA replication for more details.)
