Why is it important that the cell's DNA is duplicated before cell division?
It is important for the cell's DNA to be duplicated before cell division to ensure that each new daughter cell receives a complete set of genetic information. This ensures the genetic continuity of the organism and that the daughter cells are able to function properly.
Where are chromatids found in a cell?
Chromatids are found in the nucleus of a cell during the late stages of the cell cycle, specifically during mitosis and meiosis. They are duplicated copies of a chromosome connected by a centromere, and each chromatid contains genetic material that will eventually be divided and passed on to daughter cells.
How many sister chromatids are there in a duplicated chromosomes?
There are two sister chromatids in a duplicated chromosome. Each sister chromatid is an identical copy resulting from DNA replication during the S phase of the cell cycle.
What phase do cohesins join sister chromatids of duplicated chromosome?
Cohesins join sister chromatids during the S phase of the cell cycle. This is when DNA replication occurs, resulting in the formation of identical sister chromatids bound together by cohesin proteins.
In mitosis's chromatids line up in the middle of the cell during?
In mitosis, chromatids line up in the middle of the cell during metaphase. This alignment ensures that, during anaphase, the chromatids can be separated and pulled to opposite poles of the cell, ensuring each daughter cell receives an identical set of chromosomes.
What contains uncondensed chromosomes that have been duplicated?
The nucleus of a cell contains uncondensed chromosomes that have been duplicated. During the interphase of the cell cycle, before cell division, the chromosomes replicate and form sister chromatids that are still uncondensed and spread throughout the nucleus.
Why is it important that the cell's DNA is duplicated before cell division?
It is important for the cell's DNA to be duplicated before cell division to ensure that each new daughter cell receives a complete set of genetic information. This ensures the genetic continuity of the organism and that the daughter cells are able to function properly.

In mitosis chromatids line up in the middle of the cell?
Chromatids line up during the metaphase of the cell cycle.
How many sister chromatids are there in a duplicated chromosomes?
There are two sister chromatids in a duplicated chromosome. Each sister chromatid is an identical copy resulting from DNA replication during the S phase of the cell cycle.
What holds together the sister chromatids during the cell cycle?
centromeres
When during mitosis when do duplicated chromosomes separate?
Duplicated chromosomes separate during anaphase of mitosis. During this phase, the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers.
What phase do cohesins join sister chromatids of duplicated chromosome?
Cohesins join sister chromatids during the S phase of the cell cycle. This is when DNA replication occurs, resulting in the formation of identical sister chromatids bound together by cohesin proteins.
What is a chromosome has been duplicated the two indentical portions that are attached by their centromere?
A duplicated chromosome, with two identical portions attached by their centromere, is referred to as a sister chromatid. Sister chromatids are produced during DNA replication and are important for ensuring accurate distribution of genetic material during cell division.
In mitosis's chromatids line up in the middle of the cell during?
In mitosis, chromatids line up in the middle of the cell during metaphase. This alignment ensures that, during anaphase, the chromatids can be separated and pulled to opposite poles of the cell, ensuring each daughter cell receives an identical set of chromosomes.
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.
During the G2 phase of the cell cycle DNA material is being duplicated true or false?
False. During the G2 phase, the cell is preparing for cell division by synthesizing proteins and organelles. DNA material is already duplicated during the S phase of the cell cycle.
