In which phase do the replicated chromosomes separate?
anaphase
Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
What attaches to chromosomes to pull them apart?
The movement of chromosomes is facilitated by a structure called the mitotic spindle, which consists of microtubules and associated proteins. Spindles extend from centrioles on each of the two sides (or poles) of the cell, attach to the chromosomes and align them, and pull the sister chromatids apart.
What is the duplicating and separating of chromosomes called?
Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. …
Do duplicated chromosomes separate during mitosis?
The mitotic phase is a multistep process during which the duplicated chromosomes are aligned, separated, and move into two new, identical daughter cells. The first portion of the mitotic phase is called karyokinesis, or nuclear division.
Which are replicated during interphase?
During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides.
What is a replicated chromosome called?
A chromatid is one of two identical halves of a replicated chromosome. Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.
What is a duplicated chromosome?
Chromosome duplication: Part of a chromosome in duplicate. A particular kind of mutation involving the production of one or more copies of any piece of DNA, including sometimes a gene or even an entire chromosome. A duplication is the opposite of a deletion.
In which part of interphase are the chromosomes replicated?
S phase
Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids (see figure below).
Why is DNA replicated before a cell divides?
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.
Which are replicated during interphase quizlet?
During interphase, a cell increases in size, synthesis new proteins and organelles, replicates its chromosomes, and prepares for cell division by producing spindle proteins. Explain how the following terms are related to one another: DNA, centromere, chromosome, chromatid.
How do replicated chromosomes separate in plant cells?
* Replicated chromosomes separate by attaching to some other structural feature of the cell. Cytokinesis in plant cells: Which of the following statements are true of cytokinesis in plant cells?
How many copies of duplicated chromosomes are attached at their centromeres?
* 2 copies of the duplicated chromosome are attached at their centromeres before separation. Both Bacteria and Eukariotes: * Chromosomes replicate before cell division. * Replicated chromosomes separate by attaching to some other structural feature of the cell.
Will the sister chromosomes move to the poles of the cell?
Will this cell elongate during mitosis? (yes) 2. Will the sister chromatids separate from each other? (yes) 3. Will the chromosomes move to the poles of the cell? (no) Comparing chromosome separation in bacteria and eukaryotes bacteria only: *Chromosome separation begins at the origin of replication on DNA. Eukaryotes only:
What happens to duplicated chromosomes before separation?
* Before separation, duplicated chromosomes condense. * Nuclear envelope fragments, permitting chromosome separation. * 2 copies of the duplicated chromosome are attached at their centromeres before separation. Both Bacteria and Eukariotes:
