What phase does the chromosomes condense into chromatids?
prophase
When do chromosomes form in the cell cycle?
1 Prophase - DNA coils up , chromatids form and chromosomes become visible, nuclear envelope dissolves, and spindle fibers form.
Which phase are sister chromatids visible and attached to each other at the centromere?
Sister chromatids are visible and attached to each other at the centromere during the prophase and metaphase stages of cell division, specifically in mitosis and meiosis. In prophase, the chromatids condense and become more distinct, while in metaphase, they align at the cell's equatorial plane, still connected at the centromere. This attachment is crucial for their proper segregation into daughter cells during the later stages of cell division.
What stage of mitosis can you visualize DNA?
Prophase. Prophase occurs directly after the G2 phase of interphase. In early Prophase, the sister chromatids condense further, becoming visible with a microscope.
What phase does chromosomes first appear to be double?
Chromosomes first appear to be double during the S phase of the cell cycle when DNA replication occurs. This results in two identical sister chromatids joined by a centromere in preparation for cell division.
What is the the mitosis stage when the chromatids are visible?
The stage of mitosis when the chromatids are visible is the metaphase stage. During metaphase, the duplicated chromosomes line up along the center of the cell, with their chromatids attached to the spindle fibers.
When during mitosis are sister chromatids visible?
Sister chromatids are visible during metaphase of mitosis, where they align along the metaphase plate in the center of the cell. This is when the chromosomes are most condensed and easily visible under a microscope.
How many cells are in prophase?
During prophase, a cell typically contains 46 chromosomes, which are made up of two sister chromatids each. This means there are a total of 92 chromatids in a cell during prophase.
What phase does the chromosomes condense into chromatids?
prophase
When do chromosomes form in the cell cycle?
1 Prophase - DNA coils up , chromatids form and chromosomes become visible, nuclear envelope dissolves, and spindle fibers form.
The phase of mitosis during which chromosomes become visible and the centrioles separate from one another is?
Prophase. The chromosomes become more conspicuous because they gradually condense during prophase. The centrioles separate in animal cells; plant cells lack centrioles.
The replicas of chromosomes that form during prophase are called what?
During prophase, a chromosome is composed of tightly coiled DNA and protein molecules. Each chromosome exists as a pair of identical sister chromatids which are held together at the centromere.
Which phase are sister chromatids visible and attached to each other at the centromere?
Sister chromatids are visible and attached to each other at the centromere during the prophase and metaphase stages of cell division, specifically in mitosis and meiosis. In prophase, the chromatids condense and become more distinct, while in metaphase, they align at the cell's equatorial plane, still connected at the centromere. This attachment is crucial for their proper segregation into daughter cells during the later stages of cell division.
What stage of mitosis can you visualize DNA?
Prophase. Prophase occurs directly after the G2 phase of interphase. In early Prophase, the sister chromatids condense further, becoming visible with a microscope.
Are chromosomes now visible during prophase?
In prophase there's just the condensation of the chromatin material into chromosomes...& nuclear membrane disappears but the chromosomes aren't clearly visible,they are better visible during metaphase..!
What chromatids identical halves of a duplicated parent chromosome formed during the prophase stage of mitosis the halves are held together by a centromere?
The chromatids are the identical halves of a duplicated chromosome that are held together by a centromere. During the prophase stage of mitosis, the chromatids condense and become visible as distinct structures. These chromatids will eventually separate during anaphase and move to opposite poles of the cell.
How does tetrad form in prophase 1 of meiosis?
4 chromatids
