What is inside a nucleus that contains information about cells?
ahh pores
Ultra structure of nucleus?
The cell's ultrastructure, the detailed structure of the cell, has been studied with an electron microscope. Beam of electrons are focused by electromagnets so that a maximum magnification of about 500 000 times the real size of the specimen is possible.The most important feature of the cell which can be identified from a cell's ultrastructure is the nucleus, which is about five micrometers in size. The nucleus contains chromosomes (genes made of DNA which control cell activities), separated from the cytoplasm by a nuclear envelope. A double membrane within the envelope contains small holes called nuclear pores (100nm in diameter) which allow the transport of proteins into the nucleus. DNA in the nucleus is continuously used to manufacture proteins.
Where in the cell is the nuclear pores located?
"Nuclear pores are large protein complexes that cross the nuclear envelope, which is the double membrane surrounding the eukaryotic cell nucleus."
Which feature enables the nucleus to send and receive information through the nucleus membrane?
pores
What surrounds all cells?
All cells are surrounded by a semi-permeable cell membrane
Double layered membrane with pores surrounding the nucleus?
The nuclear envelope is a double-layered membrane that surrounds the nucleus. The nuclear envelope has nuclear pores that regulate materials going in and out of the nucleus.
What contains a nuclear membrane?
Nuclear membrane, or nuclear envelope, is a double membrane that surrounds the nucleus. It separates the nucleus (and inside it the DNA) from the cytosol. However, it has pores (nuclear pores) which provides passage for necessary substances to cross into the nuclear or out from the nuclear. It, also, is adjacent to the Rough Endoplasmic Reticulum.
What is inside a nucleus that contains information about cells?
ahh pores
What are the parts in the structure of the nucleus?
The parts in the structure of nucleus are nuclear membrane, Nuclear pores, Nuclear plasm, Nucleoli, Chromatin.
What is found inside the nucleus and contains the cells genetic information?
Pores
What structure surrounds the DNA and controls what enters and leaves the nucleus?
The nuclear envelope. For more information on the nuclear envelope, you could check out the article on wikipedia.
What is the structure around the nucleus called?
In the cell, it is called the nuclear membrane. Inside the nucleus is DNA and nucleoplasm.
Is bounded by a double membrane with pores and contains the cell's genetic material?
The mitochondria and the chloroplast.
What is a double membrane which encloses the nucleus and contains many openings called pores?
nuclear membrane
What is the skin of a nucleus called?
The covering of the nucleus is called the nuclear membrane. The nuclear membrane contains pores called nuclear pores. These pores allow ribosomes made in the nucleolus (which floats inside the nucleus) to be sent out onto the cytoplasm or to attach to the endoplasmic reticulum.
This is found inside the cell membrane surrounding the nucleus?
the membrane that surrounds the nucleus is the nuclear envelope. It has two layers, an inner and outter layer; each layer is made up of a phospolipid bilayer. There are small holes in the nucleur envelope called pores.
How does the MRNA get out of the nucleus?
It gets out through the nuclear pores and enters the cytoplasm.
