What is the major event in mitisis?
The major event in mitosis is the separation of sister chromatids, which occurs during the anaphase stage. Prior to this, during prophase, chromosomes condense and become visible, and the nuclear envelope breaks down. In metaphase, chromosomes align at the cell's equator, and during anaphase, the spindle fibers pull the sister chromatids apart to opposite poles of the cell. Finally, in telophase, the chromatids decondense back into chromatin, and the nuclear envelope re-forms, leading to the completion of cell division.
How can nuclear energy benefit America?
Nuclear energy is a alternate fuel source to coal that can create large amounts of energy without polluting the air with carbon dioxide. Installing these in America would lower the need and demand for foeign oil and fuel. However there is a downside to nuclear energy; the nuclear reactor may overhaet and explode.
Why does japan use nuclear power?
Limited fossil fuels, air quality problems, need for electricity.
Why did the UK sign the nuclear non-proliferation treaty?
UK is a permanent member of the United Nations Security Council and has signed the treaty. Some nations agree that nuclear bombs should not used no matter the need.
Merits and demerits of nuclear family?
MERITS : the merits of nuclear family is that if u are a house wife or even working:::it will be easier to handle it as the family is small........... DEMERITS : it is not good to have a small family as if u need a help.......there is no help.u are alone/............
Does the nuclear envelope have prokaryotes?
No, prokaryotes don't have neclear envelopes in them either.
What structure identifies a eukaryote as a eukaryote?
There is no nuclear envelope that encloses the genetic material in prokaryotes.
How does the absence of a nuclear envelope in the prokaryotes prevent prokaryotes from controlling gene expression by modifying RNA after transcription?
In eukaryotes, mRNA is processed inside the nucleus before being shipped out into the cytoplasm for translation. Specifically, a strand of pre-mRNA (or immature mRNA) has a GTP cap added to its 5' end, a poly-adenine tail added to its 3' end, and it has its introns spliced out. Since prokaryotes don't have nuclear envelopes, they don't have an area to do this.
Where are hereditary or genetic materials inside a Cell found?
They are located within the Chromosome: freely floating in Prokaryotes; contained within the nuclear envelope in Eukaryotes.
What separates the cytoplasm and nucleus?
Nuclear envelope
What is the double membrane surrounding the nucleus?
The double membrane surrounding the nucleus is called the nuclear envelope. It consists of an outer membrane and an inner membrane, with nuclear pores that control the movement of molecules in and out of the nucleus.
Why doesn't bacteria have their DNA encased in a nuclear envelope?
They are prokaryotes so did not evolve in the same way as eukaryotes. Bacteria are "simpler" organisms but have a highly complicated structure of their own
What does the nuclear envelope do for an animal cell?
The Nuclear envelope separates the cytoplasm from the nucleus.
Where is the nuclear envelope located?
The nuclear envelope is a membrane around the nucleus of a cell.
Which stage does the nuclear envelope form?
The nuclear envelope reforms during Telophase.
What represents the nuclear membrane?
The nuclear membrane of a cell is also known as the nuclear envelope.
How does the nuclear envelope allow materials in and out of the envelope?
It does
