Although many cells go through both anaphase A and B motions, occasionally one motion takes precedence over the other. Poleward migration in anaphase requires the separation of the paired sister chromatids. The components that link the chromatids at the centromere are degraded by proteolysis, which causes chromatid separation.
Synapsis is the name given to this action. Crossing over happens during synapsis. DNA is transferred between two nonsister chromatids of a homologous pair of chromosomes during crossing over.
When nondisjunction occurs, the homologous or sister chromatids are drawn to one pole of the cell because the separation does not take place.
Therefore, One daughter cell would have more chromosomes than usual, and one sister chromatid would not split equally during the anaphase of mitosis.

B. A single-stranded RNA molecule forms.
C. The DNA transfers its information to RNA through an amino acid.
D. The DNA molecule unzips along weak hydrogen bonds.
DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. The option (D) is correct.
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Moreover, DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical.
Therefore, DNA replication is the process of creating two identical daughter strands of DNA. DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells. DNA replication occurs in S phase during the cell cycle prior to cell division.

Answer:
D
Explanation:
The first step in DNA replication is to 'unzip' the double helix structure of the DNA molecule. This is carried out by an enzyme, called helicase which breaks the hydrogen bonds? holding the complementary bases of DNA together
