(a) Describe the structure of the nucleolus. (b) Describe its function. Describe the function of the following structure: Nucleolus. List the functions of the plasma membrane, cytoplasm, and nucleus. What is an important function of the eukaryotic cell membrane?
The nucleolus, also called a nucleole, is a cellular structure found within the nucleus of eukaryotic cells. There can be many nucleoli within a single cell nucleus, although normal human cells all have only one nucleolus. It is composed of nucleic acids and proteins and is responsible for ...
Nucleus is the organelle which encloses the genetic material in eukaryotic cell. It is a double membrane bound organelle. It also contains RNA and protein. It is the site of replication of DNA and formation of RNA.Answer and Explanation: Structure of Nucleus...
What is the name of the cell organelle which synthesizes plasma membrane? What do prokaryotic cells lack? a. nucleolus b. cell membrane c. all of the above What organelles does a plant cell have that an animal cell does not? What type of cell has membrane-bound organelles and a nucleus...
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.
What is the cell nucleus made of? As it contains genetic material, it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components:nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasmare some of these components. ...
What is structure of DNA? The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cy...

Ribosomal subunits are assembled in the nucleolus, and assembly is therefore dependent on efficient targeting of r-proteins to this sub-organelle structure. Nuclear localization of proteins is usually mediated by one or more stretches of basic amino acids, nuclear localization signals (NLSs), that ...
