In which phase nucleus is visible in cell?
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible.
Which phase of mitosis has two nuclei?
telophase
During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell.
What is the second phase of mitosis?
When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles. As a result, the spindle microtubules now have direct access to the genetic material of the cell.
What is a prophase 2?
Prophase II is the phase that follows after meiosis I, or after interkinesis if present. If interkinesis takes place, the nuclear envelope and the nucleolus disintegrate during prophase II. The chromosomes are condensed. The centrosomes replicate and move towards the opposite poles.
What happens during the phase where two new nuclei form?
Mitosis is the process of cell reproduction. During this process the DNA is duplicated before the nucleus spilts into two identical nuclei each with their own identical copy of the parent cell, creating two new identical daughter cells. What happens during the s phase of mitosis?
What are the four phases of mitosis in the cell?
Mitosis is the division of the nucleus to form two genetically identical nuclei. There are four phases of mitosis: prophase, metaphase, anaphase and telophase.
What are the phases of the somatic cell cycle?
Every somatic cell undergoes a phase called mitosis. Mitosis is the division of the nucleus to form two genetically identical nuclei. There are four phases of mitosis: prophase, metaphase, anaphase and telophase.
What happens when two nuclei fuse in the Sun?
The process in which the nucleus divides to form two identical nuclei is called mitosis. Energy is produced in the sun when two? ..particles (nuclei) fuse together to form heavier nuclei. Initially, two protons fuse together (hydrogen atom nuclei) to form deuterium.
