The S-phase is during interphase, which means there are no chromosomes. DNA is replicated in the S-phase ("s" for synthesis). It can only be replicated in the form of chromatin, not wrapped up in chromosomes.
During meiosis, the number of chromosomes is halved. This process results in the formation of sex cells (sperm and egg) with half the number of chromosomes as the parent cell.
During mitosis, the number of chromosomes remains the same. The cell duplicates its chromosomes and then separates them evenly into two daughter cells, each with the same number of chromosomes as the original cell.
the chromosomes pairs line in the center of the cell the chromosomes pairs line in the center of the cell
When chromosomes fail to separate during meiotic divisions, it can lead to an abnormal number of chromosomes in the resulting cells. This condition, known as nondisjunction, can result in genetic disorders such as Down syndrome.
The chromosomes are dividing and becoming new chromosomes.
what happens to chromosomes during anaphase
what happens to chromosomes during anaphase
Yes it is a phase of mitosis. It the the phase in thich the chromosomes duplicate. As a result each chromosome ha 2 sister chromatids
Homologous chromosomes pairs pull away from each other.
Chromosomes Are Checced for errors
During meiosis, the number of chromosomes is halved. This process results in the formation of sex cells (sperm and egg) with half the number of chromosomes as the parent cell.
what happens during meiosis that results in a defect characterized by the deletion of chromosomes
chromosomal Translocation
The Chromosomes separate from each other and move to opposite ends of the cell.
During mitosis, chromosomes are in their most condensed form during metaphase
Cell division takes place in the cells and chromosomes line up along the center of the cell
The pairing up of maternal and paternal chromosomes during meiosis happens in the prophase I stage. This pairing is called synapsis and results in the formation of a structure called a tetrad.
