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.
