Metaphase
Chromosomes can be seen in the metaphase stage of the cell cycle, when they align along the center of the cell prior to division.
Chromosomes replicate during the S phase of the cell cycle, which occurs in between cell divisions. This process ensures that each daughter cell receives a complete set of genetic material during cell division.
The phase of mitosis where the chromosomes line up at the center of the cell is called metaphase. At this stage, the spindle fibers attach to the centromeres of the chromosomes, aligning them along the metaphase plate in preparation for their separation.
Chromosomes are duplicated during the S phase of the cell cycle, which occurs during interphase. This is when DNA replication takes place to ensure that each daughter cell receives a complete set of chromosomes during cell division.
Metaphase
During the G1 phase of the cell cycle, chromosomes are not yet duplicated and appear as a single line of chromosomes within the cell. This is before DNA replication occurs in the S phase and chromosomes are temporarily duplicated.
Chromosomes can be seen in the metaphase stage of the cell cycle, when they align along the center of the cell prior to division.
Chromosomes migrate to the equator of the cell and arrange themselves during the metaphase stage of mitosis. This stage occurs after prophase and before anaphase, and is characterized by the alignment of chromosomes in a single plane at the center of the cell.
A cell's DNA is copied during this phase. At the end of this phase, each chromosomes consists of two chromadtids attached at he centromere.
Chromosomes do not duplicate during metaphase in the cell cycle. Chromosome duplication occurs during the S phase of interphase, before the cell enters mitosis. During metaphase, the duplicated chromosomes align at the center of the cell before separating into two daughter cells during anaphase.
Chromosomes replicate during the S phase of the cell cycle, which occurs in between cell divisions. This process ensures that each daughter cell receives a complete set of genetic material during cell division.
Strictly speaking, the chromosomes are not copied during mitosis but already before cell division takes place. This phase is called INTERPHASE and is again divided into three phases, G1 (first gap), S (synthesis), and G2 (second gap). The replication of chromosomes only happens in the S phase.
The phase of mitosis where the chromosomes line up at the center of the cell is called metaphase. At this stage, the spindle fibers attach to the centromeres of the chromosomes, aligning them along the metaphase plate in preparation for their separation.
Chromosomes duplicate during the S phase of the cell cycle, which occurs after the G1 phase and before the G2 phase. In this phase, DNA replication takes place to create identical sister chromatids that will eventually be separated during cell division.
Chromosomes are duplicated during the S phase of the cell cycle, which occurs during interphase. This is when DNA replication takes place to ensure that each daughter cell receives a complete set of chromosomes during cell division.
A diploid cell in G1 phase has 46 chromosomes.
