Does the nuclear envelope re-forms during anaphase?
No. The nuclear envelope does not re-form until telophase.
Which is the phase where a nuclear envelope re-forms around each cluster of chromosomes?
telophase
What is a list of the four phase of mitosis in order?
Phase 1- Mitosis begins. Chromosomes condense from long strands into rodlike structures. Phase 2- The nuclear membrane is dissolved. Paired chromatids align at the cell's equator. Phase 3- The paired chromatids separate and move to opposite sides of the cell. Phase 4- A nuclear membrane forms around each set of chromosomes, and the chromosomes decondense. Mitosis is complete.
Is it true that the nucleus is part of the nuclear envelope?
No, the nucleolus is in the center of the nucleus.
What phase are nuclear membrane reform?
During mitosis, it is when the cell is in telophase.
Does the nuclear envelope re-forms during anaphase?
No. The nuclear envelope does not re-form until telophase.
Which event occurs during prophase-?
the chromatin condenses into thick thread like structure that later becomes chromatids. [ the spindle fibers form ]
Which is the phase where a nuclear envelope re-forms around each cluster of chromosomes?
telophase
When the nuclear envelope re forms?
Telophase
What is the new nuclear envelope forms?
telophase :P
What happens during telephase in cell division?
A new nuclear envelope forms around each region of chromosomes
What are the stages of mitosis in order from 1-4?
Prophase - chromosomes condense and become visible, mitotic spindle starts to form, nuclear envelope dissolves Metaphase - spindle fibres attach to Choromsomes, chromosomes line up at the equator of the cell Anaphase - chromatids are pulled apart Telophase - New nuclear envelope forms, cell begins to pinch in two
What does nuclear envelope pores mean?
The nuclear envelope is the nuclear membrane. Nuclear pores are openings in the nuclear membrane that allow for the movement of materials into and out of the nucleus. For example, the mRNA that forms in the nucleus during DNA transcription leaves the nucleus through the pores in the nuclear membrane, and attaches to ribosomes in the cytoplasm and rough endoplasmic reticulum.
Meiosis 2 during which the nuclear envelope reforms around genetic material in four new haploid cells?
During meosis 2, there is a phase called telophase 2 where the nuclear envelop forms around the chromosomes of the haploid cells
What term describes centromeres uncoupling sister chromatids separating and the two new chromosomes moving to opposite poles of the cell in miosis?
telophase it is actually Anaphase where the sister chromatids are separated and they are pulled to opposite poles. Telephase and Cytoknesis is when the cell forms the nuclear envelope and nucleolus. The cell is then divided at the Metaphase plate and the two new daughter cells appear.
Which type of organelle forms a membranous system of tubular canals which is continuous with the nuclear envelope and branches through the cytoplasm?
lysosme
Does a cell make a copy of its DNA during the stage of the cell cycle called mitosis?
No. Mitosis is strictly the stage of the cell cycle where the chromatin condenses into chromosomes, the nuclear envelope dissolves, the chromosomes line up on the metaphase plate, spindly fibers attach to the kinetochores of each chromosome and "pull" sister chromatids apart to opposite poles of the cell. Then the cell pinches off and forms a nuclear envelope around the DNA. The stage in the cell cycle where a cell duplicates its genetic material is called the S phase, preceded by the G1 phase, followed by the G2 phase, then mitosis and cytokinesis.
