welcome to moomoomath and science in this video I'd like to look at the nucleus I've always heard that the nucleus is the brain of the sail but why is it the brain and what are the major parts of the nucleus the nucleus is a large organelle in fact you can see the nucleus with a compound microscope here it is inside a cheek cell I'd like to look at four main components of the nucleus first the nuclear membrane
00:30
nuclear pores nucleoplasm in the nucleolus the nucleus is surrounded by a nuclear membrane and that this is very similar to at the cell membrane and it is also composed of two layers it protects and houses the other parts of the nucleus you can also find ribosomes on the outside of the nuclear membrane up next are the nuclear pores these are openings found on the nuclear membrane they allow items to move in and out of
01:04
the nucleus an example would be messenger RNA you are heading through a nuclear pore and into the plant cell nucleus the nucleus is home to a plant's DNA like meters and meters of cell blueprints the DNA make the plant what it is nucleoplasm is a gel-like or watery material found inside the nuclear membrane you will find the DNA suspended
02:01
in the nucleoplasm the nucleolus is almost like a nucleus inside the nucleus it has a very high concentration of DNA it is also the site of transcription which is the starting point of protein synthesis this is how the nucleus controls the cell it has all the information on how to make the stuff like proteins for the cell these proteins are used for many purposes inside the cell raba somes are also made
02:35
at the nucleolus all eukaryotic cells have a nucleus and bacteria and other prokaryotic cells do not have a nucleus I hope that helps thanks for watching and moomoomath uploads a new math and science video every day
