DNA replication is the process that leads to the formation of the two chromatids.
DNA REPLICATION:
- DNA replication is the process by which the information in a DNA molecule is used to synthesize another to make two identical copies.
- DNA replication occurs prior to every cellular division in order to enable daughter cells have the correct amount of genetic material.
- DNA molecules are borne on structures called chromosomes. Hence, when the information of a DNA molecule is duplicated, there is need for another chromosome to harbor the replicate.
- Chromosomes containing identical DNA molecules are termed sister chromatids. Sister chromatids are joined together by a centromere.
- Therefore, DNA replication is the process that leads to the formation of the two chromatids.
