These subunits leave the cell's nucleus via pores found in the nuclear membrane. They enter the cytoplasm of the cell, where they come together to form a functioning ribosome. Since ribosomes' major function in a human body is to synthesize proteins from amino acids, cells that need more ...

Plant cells are the basic unit of life of various types of plants. These cells develop into tissues and organs that a plant needs to perform its essential functions and activities. Like animal cells, plant cells contain structures such as the nucleus, mitochondria, ribosomes, and Golgi ...
A) The plasma membrane is a single-layered membrane that surrounds the nucleus of the cell. B) The plasma membrane is a double layer of protein enclosing the plasma. C) The plas What cell structure regulates the composition of the intracellular fluid? a. Plasma membrane b. Cell wall c. ...
The fluid allows for easy transportation of these molecules and enzymes within the nucleus. As the nuclear membrane is impermeable to many types of molecules, protein complexes in the membrane, called nuclear pores, allow substances to be transported between the cytoplasm and nucleoplasm. The nuclear...
The Nucleus: In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromosomes are identical in each cell, thanks to the process of cell division. ...
transparent areas of prokaryotic cells that contain DNA. Some DNA is contained in other areas of the cell as well, depending on the organism, but the nucleoid is the primary center for DNA transcription and replication. Prokaryotes do not have a membrane-bound, defined nucleus, so the nucleoid...
A nucleon is a collective term for protons and neutrons inside an atomic nucleus, while the nucleus is the core of an atom, containing nucleons and thus most of the atom's mass.
