How does the nuclear envelope allow for cell reproduction?
At the time of nuclear division the nuclear envelope get disintegrated to provide enough space to the chromosomes to move at two poles of the spindle. When the division is complete the nuclear envelope organizes again around these daughter nuclei.
Which phase of mitosis does the nuclear envelope reform and the nucleoli reappear?
The nuclear envelope reforms and the nucleoli reappear during telophase of mitosis. This phase marks the end of nuclear division as the newly formed daughter nuclei begin to re-establish their nuclear envelopes.
What happens to the nuclear envelope towards the end of cell division?
During cell division, the nuclear envelope breaks down to allow the chromosomes to move to opposite poles of the cell. Once the chromosomes are properly aligned, a new nuclear envelope reforms around each set of chromosomes, resulting in two new nuclei in the daughter cells.
What is formed from nuclear fusion?
Gaseous planets
Is it true that Hydrogen and Helium were formed by nuclear reaction in the stars and other elements were formed after the Big Bang?
Close, but not exactly. Hydrogen is not formed by nuclear reactions in stars, hydrogen was formed not long after the Big Bang, when the expanding universe had cooled sufficiently that an electron and a proton could combine to form a hydrogen atom. Helium and all the other elements that are heavier than hydrogen, were formed by the process of nuclear fusion, in stars.

What job does the nucleus membrane have?
The nuclear membrane, or more often called nuclear envelope, isolates a eukaryotic cell's chromatin(DNA) from the rest of the cytoplasm. The nuclear envelope is believed to have formed from the infolding of the cell membrane(basically the same process that also formed the endoplasmic reticulum). Unlike the cell membrane the nuclear envelope contains pores which are essential for the movement of mRNA from the nucleus out to the cytoplasm where ribosomes are located so protein synthesis can be undertaken.
Which phase of mitosis does the nuclear envelope reform and the nucleoli reappear?
The nuclear envelope reforms and the nucleoli reappear during telophase of mitosis. This phase marks the end of nuclear division as the newly formed daughter nuclei begin to re-establish their nuclear envelopes.
What are words that can be formed by the word ENVELOPE?
Some of the words that can be formed by envelope are:eelelelevenelopeeneonepeeeveevenleeleveelevelloloneloplopeloveneenonoelnopenoveloleononeopenovenpeepeelpeevepenpeonpoleveevole
What stage is the nuclear membrane formed again?
The nuclear membrane is reformed during the telophase stage of mitosis or meiosis. This process involves the reassembly of the nuclear envelope around the separated daughter chromosomes to form two distinct nuclei in each daughter cell.
What forms during anaphase?
chromosomes and the mitotic spindles are formed during anaphase
What happens to the nuclear envelope towards the end of cell division?
During cell division, the nuclear envelope breaks down to allow the chromosomes to move to opposite poles of the cell. Once the chromosomes are properly aligned, a new nuclear envelope reforms around each set of chromosomes, resulting in two new nuclei in the daughter cells.
A strand of replicated DNA formed during prophase is?
A persistent RNA-DNA hybrid is formed during transcription at a phylogenetically conserved mitochondrial DNA sequence.
In which phase of mitosis does the nuclear envelope reform around the chromosomes?
The reformation of the nuclear envelope around the chromosomes occurs during the telophase stage of mitosis. At this stage, the separated sister chromatids reach the opposite poles of the cell, and a new nuclear envelope is formed around each set of chromosomes.
Components of the nucleus?
The main components of the nucleus are the nucleolus, chromatin (DNA and associated proteins), nuclear envelope, and nuclear pores. The nucleolus is involved in ribosome production, chromatin contains the genetic material, the nuclear envelope is a double membrane that encloses the nucleus, and nuclear pores allow for the exchange of materials with the cytoplasm.
How many nuclear membranes must form when a single dividing cell reaches telophase?
Two nuclear membranes must form, as the nuclear envelope of the parent cell breaks down during prophase, and two separate daughter nuclei are formed by the end of telophase in mitosis.
How is uranium nuclear formed?
Uranium is formed in the universe by stellar nucleosynyhesis.
