What else can I help you with?
What happens to the cytoplasm as the cell progresses through telophase?
It divides
What structure within the nucleus becomes indistinct and finally disappears as the cell progresses through prophase?
nucleolus
What happens to the nuclear membrane as the cell progresses through prophase?
disappear you go do yourself and freaking get a life!
What happens to the pressure as one progresses through the layers of the earth from the inner core out the crust?
pressure decreases
When does meiosis 1 begin?
Meiosis I begins after the cell has completed interphase, during which the DNA is replicated. This phase initiates with prophase I, where homologous chromosomes pair up and exchange genetic material through a process called crossing over. Meiosis I then progresses through metaphase I, anaphase I, and telophase I, ultimately resulting in two haploid daughter cells.
What happens to cell membranes during cell division?
During prophase the nuclear membrane disintegrates. The metaphase through anaphase the molecules are not formed as membranes. During telophase it reintegrates and in interphase it is present as normal.
In mitosis when does the nucleolus disappear?
The nuclear membrane and nucleolus both disappear during prophase of mitosis and meiosis.The nucleolus is a region of the interphase nucleus containing many of the genes that code for ribosomal RNAs (rRNAs). The genes are on a number of different chromosomes, which have to folded in such a way that these genes end up in the same region of the nucleus. During prophase the chromosomes separate from one another, and so the nucleolus disappears.The nuclear membrane has to be taken out of the way before metaphase, so that the chromosomes can move out of the confines of the nucleus. Enzymes break down the membrane into small fragments, which travel through the endoplasmic reticulum to the poles. They will be used to construct new nuclear membranes around the daughter nuclei during telophase.##One thing should be remain that nuclear membrane never disappeared just disorganized when RNA come out from nucleolus. Again its reorganized when RNA form in nucleolus.prophase
What are the phases that meiosis goes through?
meiosis goes through the prophase, metaphase, anaphase, and telophase two time.

Where rRNA is formed?
These are known as Ribosomes, the " workbench " on which proteins are synthesized.
What happens in the telophase and cytokinesis?
during the tellophase of mitosis,the two sepsrated sister chromatids which have been drawn to the opposite poles of the cell become longer and thinner and turn into chromosomes. then the nuclear membrane and the nucleolus reappear in each pole of the cell. following this cytokinesis takes place. in the animal cell a furrow forms in the cellmembrane and deepens through th e cytoplasm spliting the parent cell into two daughter cells
What phase happens only once in meiosis?
The phase that happens only once in meiosis is prophase I, which is characterized by the pairing of homologous chromosomes and the exchange of genetic material through crossing over. This phase is unique to meiosis and does not occur in mitosis.
