this chromosome has two chromatids, joined at the centromere. what process led to the formation of the two chromatids?
ollegr [7]

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.
