Does the cell nucleus divide during mitosis?
Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. This process ensures that each daughter cell will contain one exact copy of the parent cell DNA.
What is stored in the nucleus during mitosis?
The genetic information of the cell, or DNA, is stored in the nucleus. During mitosis, two nuclei (plural for nucleus) must form, so that one nucleus can be in each of the new cells after the cell divides. In order to create two genetically identical nuclei, DNA inside of the nucleus must be copied or replicated.
What is inside the nucleus of a cell?
The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell’s genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.
What happens during anaphase of mitosis?
During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
Which of the following occur during mitosis?
These basic events of mitosis include chromosome condensation, formation of the mitotic spindle, and attachment of chromosomes to the spindle microtubules. Sister chromatids then separate from each other and move to opposite poles of the spindle, followed by the formation of daughter nuclei.
What happens to the nucleus in 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. During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes.
What is a nucleolus in a cell?
Listen to pronunciation. (noo-KLEE-uh-lus) An area inside the nucleus of a cell that is made up of RNA and proteins and is where ribosomes are made. Ribosomes help link amino acids together to form proteins.
