  • What is the function of the nucleolus?
The main function of the nucleolus is to synthesize RNA. The nucleolus will also assemble ribosomes. Ribosomes are the part of the cell which produces protein so the nucleolus is very important in the production of protein synthesis. The nucleolus deals with 50% of the production of RNA within the cell so we can see how important the nucleolus is to our whole bodies.
  • What is the nucleolus?
The nucleolus is found in the nucleus of a cell and is one of the most important parts of the cell. The nucleolus is surrounded by a membrane and it contains the DNA and the RNA of the cell. To make it easier to understand it may be referred to the brain of the cell as this is where instructions are sent to other parts of the cell and it has a very important controlling function within the cell.

  • Where will I learn more about the nucleolus?
This is a topic that is commonly dealt with in advanced biology for students who are aged six plus. If you are struggling to understand anything in your biology classes it is best to speak to your biology teacher and ask for some extra help. Your teacher may not have the time or resources to give extra classes so you should ask for examples of text books that could help. You could also begin a study group where students could come together and help each other with aspects of the course that you do not understand. It is likely that there will be someone within the group that is very good at explaining one topic but will need help with a different area of the course.

Nucleus is the master organelle of all living cells .It is called as the brain of the cell. All the major functions of the cell are performed under the instruction of nucleus. In animal cells it is present in the middle of the cell whereas in plant cells it is pushed towards the periphery. Nucleus contains chromatin material.The chromatin material consist of DNA which is the hereditary material of the cell.The major functions are:-
1.It is involved in cell division.
2.It stores all the information that is to be transferred to the next generation.
3.Assembly of ribosomes takes place in the nucleolus present inside the nucleus.
4.DNA replication and transcription processes take place inside the nucleus.
Transcription is the formation of mRNA. This messenger RNA then plays its role in the translation, the process of protein synthesis.Thus the information generated by nucleus governs the formation of enzymes and other proteins that carry out all the processes of body.

Not all living cells have nuclei, only eukaryotes have a nucleus, prokaryotes such as bacteria have no nucleus, or any other double membraned organelles.

The nucleus of a cell is the most important part of a cell as it contains the genetic material such as DNA molecules with a large variety of proteins. These molecules combined with proteins form chromosomes. The function of a nucleus in a cell is to control the activities of the cell by maintaining and regulating the genes present in the chromosomes.

The nucleus is the central information processing center in the cell. It is usually the largest and most prominent organelle and can be seen using an ordinary light microscope. It is usually spherical, about 10 micrometers in diameter and has a darker patch called the nucleolus.

The nucleus is enclosed within its own membrane, the nuclear membrane, or nuclear envelope. This, like all membranes in the cell is a lipid bilayer.

Inside the nucleus is the DNA of the cell. This complex molecule carries all the information, in coded form, that the cell needs to make a complete copy of itself in cell division. The genes in the DNA are also used as templates to make proteins and these, produced at different times and for different reasons, control all the activities of the cell. Most cells have a cell nucleus but there are exceptions. Red blood cells in humans and mammals lose their cell nucleus. They live only for 120 days and carry oxygen around the body ~ they don't carry out complex processes and don't divide ~ so nature has decided they can do without one when they are fully developed.

The nucleus acts as the part of a cell which regulates all cellular functions and regulates the transaction of proteins. It contains chromosomes which contain the DNA (deoxyribonucleic acid) which provides the genetic blue print for resulting offspring and it's characteristics. Besides, the nuclear transport is imperative for cellular functions. The nucleolus is a non-membrane bound structure present within the cell's nucleus and it consists of ribosomes which have RNA ( ribonucleic acid ).

The nucleus is like a head quarters that gives commands to the cell. A process that takes place there is when the DNA is transcripted into Messenger RNA for the manufacture of proteins. The nucleus also holds the DNA, and it gives energy out to the cell. It doesnt make the energy, but the energy is transported there, and its the nucleus' job to give it out to the cell. Does this help?

The word nucleus, pronounced as nukleas, refers to the essential or central part around which all the other parts are grouped or gathered around. The word is drawn from the Latin word "nuculeus". The word nucleus can mean a number of things in different fields. For instance in biology it can refer to a spherical protoplasmic structure that contains a cell's hereditary material and is located within a cell. In physics it refers to the positively charged core of the atom which contains its protons and neutrons and forms a major part of an atom's mass. In botany it refers to a seed's or a nut's central kernel. In astronomy the word nucleus is used to refer to the brightest central part of a galaxy or the head of a comet.

Nucleus is basically a membrane enclosed Organelle that can be found in all the eukaryotic cells. It is made up of Nuclear envelope, cellular cytoplasm, Nuclear lamina, nuclear pores, cytoskeleton etc.

The most important function of Nucleus is that it contains most of the genetic material of the cell. This genetic material is organized as multiple linear DNA molecules along with proteins. It controls the gene expression and also replicated the DNA During cell cycle. It is a place for the genetic transcription. It also controls the contents of cell and also the cytoplasm.

The nucleus is the main brain of the cell, it sends messages around the brain telling the cell what to do and the nucleus controls all of the cell activities. It is basically the cell director.

A nucleus controls all the activities of the cell including cell repair. It is made up of chromosomes which are made up of DNA(deoxyribonucleic acid)and proteins. Genes are part of nucleus which store information to be passed down from one generation to another.

The nucleus is located towards the middle of the cell. Its job is to control the activity going on in the cell, similar to a control panel on a computer

1..DNA plays significant role in the inheritance of characters as well as in controlling or regulation the cell activities.

2.the number of chromosomes in the cells of all individual of the same species always remains constant.

A Nucleus in the highly dense center of an atom made up of Nuetrons and Nuetrons.  It is positively charged, so it keeps the negatively charged Electrons from flying away from the rest of the atom.
