The nuclear membrane is still present during the interphase of the cell cycle, which includes the G1, S, and G2 phases. During this time, the cell is not dividing but is instead growing, replicating its DNA, and preparing for mitosis. The nuclear envelope disintegrates at the start of mitosis, specifically during prophase.
What else can I help you with?
What phase is the nuclear membrane is still visible?
During prometaphase, the nuclear envelope (membrane) breaks apart. However, some fragments of the nuclear envelope are still visible.
Why is nuclear fusion not used?
Because you are using two positively charged nuclei you must have a lot of heat to overcome the repelling nature. At the moment on earth we cannot get to these temperatures - therefore at this present time it is not used.
Which one of these two process is still used today Nuclear Fission or Fusion?
Fission. Fusion has never been used on Earth, except for nuclear weapon tests.
It is possible to prepare vesicles from portions of the inner membrane of the mitochondrial components Which one what processes could still be carried on by this isolated inner membrane?
Yes, it is possible to prepare vesicles from portions of the inner membrane of mitochondria. These vesicles can still carry out processes such as oxidative phosphorylation, electron transport chain reactions, and ATP synthesis, as the inner membrane houses key proteins and complexes involved in these metabolic processes.
Do protists cells have a nucleus?
Yes, most protist cells have a nucleus. This nucleus contains the genetic material of the cell and is surrounded by a nuclear membrane. There are some exceptions, such as red algae, which have a nucleomorph instead of a traditional nucleus.
What phase is the nuclear membrane is still visible?
During prometaphase, the nuclear envelope (membrane) breaks apart. However, some fragments of the nuclear envelope are still visible.
What do they use nuclear fusion for?
Nuclear fusion is not used for any purpose at present, it is still in the experimental phase
Which cell have cell membrane?
Every cells have a cell membrane. Sometimes, the cell membrane itself is also covered by a cell wall, but The cell membrane is still present in all cells.
What happens to the nuclear membrane during prophase?
Resulting from interphase, is a genetic material in the nucleus called chromatin. The chromatin condenses in chromosomes. During prophase, the nucleoli disappear and the chromatid structure of the chromosomes becomes apparent. Since each chromosome has duplicated and now consists of two sister chromatids, the nuclear membrane dissolves so that the sister chromatids can separate. If it didn't dissolve, they'd still be held together.
Do bacterial cells have a nucleus?
bacteria do not contain a nucleus. they have their genetic material in contact with the cellular component. there is no nuclear membrane to enclose their nuclear material into a nucleus.they are devoid of compartmentalization i.e they do not have membrane bound oraganelles and as nucleus is a membrane bound organelle so it is absent. though their genetic material is still present but in contact with cytoplasm
Why used nuclear bombs at war time?
They're very destructive and last for a long time, In other words, once you've blown up a nuclear bomb somewhere, it will still be dangerous after the initial explosion has taken place. When a nuclear bomb is used there would be nuclear radiation that would still be present where the bomb hit for quite a while
Is there tonoplast in an animal cell?
Not necessarily. Tonoplast is what you call the membrane surrounding the large vacuole in plant cells, which is not present in the animal cell. However, tonoplast is still made up of phospholipid bilayers, which is also present in animal cells as well as plant cells.
Why is nuclear fusion not used?
Because you are using two positively charged nuclei you must have a lot of heat to overcome the repelling nature. At the moment on earth we cannot get to these temperatures - therefore at this present time it is not used.
Does a cell membrane help substances pass from cytoplasm into the nucleus?
The cell membrane on an animal cell is the outermost layer and acts as a protection shield. It is selectively permeable meaning it only lets certain things into the cytoplasm of the cell. The nucleus does not have a cell membrane, it simply directs the cells activities. In a plant cell there is a cell wall on the outside of the cell membrane giving the cell support and protection, but the cell membrane still provides the same function as it does on the animal cell. Post further questions if necessary! :)
Is it feasible to put up nuclear fusion plant here in the Philippines?
At the present time there is no possibility of fusion plants anywhere in the world, the next phase is the building of a large experimental plant in France (ITER), which will move research on, but still not designed to produce useful power. In my view this is at least 50 years away, before useful power plants could be built.
What part of the cell forms a barrier between the cell and it and environment?
The barrier between the external environment and the inside of the cell is the cellular membrane, or just cell membrane. A cell wall is also present in plant cells, but substances can still enter through the cell wall. Harmful substances are stopped only when reaching the cell membrane. Some unicellular bacteria (or viruses) form an external layer outside the cell membrane, known as an envelope.
Did Britain have nuclear weapons?
Yes, and still does.
