Respuesta :
In a cell cycle, the S phase or the synthesis phase is the part in which the DNA (deoxyribonucleic acid) is replicated. This result in doubling the amount of DNA present in a cell.
This replicated DNA is later condensed to form the chromosome. These chromosomes have two identical copies of DNA bind together with help of a centromere. The identical copies in each chromosome is known as sister chromatids, which get separated at the time of Anaphase.
Hence, the given blank can be filled with Sister chromatids.
Answer;
-Sister chromatids
The s phase of the cell cycle results in the production of two identical copies of each chromosome, known as Sister chromatids.
Explanation;
-The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA.
In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. The S phase only begins when the cell has passed the G1 checkpoint and has grown enough to contain double the DNA.
The most important event occurring in S phase is the replication of DNA. The aim of this process is to produce double the amount of DNA, providing the basis for the chromosome sets of the daughter cells.
-DNA replication produces two identical DNA molecules, called sister chromatids which separate during mitosis.
