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.
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 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.
The nucleus controls all the activities of the cell.it contains the information the cell needs to reproduce itself. It stores genetic material
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.
A nucleus is basically the brain it tells cells what to do and what job they do.
The nucleus is like the brain of the cell...it controls everything...its the boss =D
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.
Cell nucleus is in charge of everything around the cell like the boss
Direct the activity of the cell
The Nucleus controls all of the cells activities. It is basicly the cells 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.
It stores genetic information in the cell.
It gives energy its the power house
The job of the Nucleus is it controls what happens in the cell
It is a center of the plant cell and animal cell.
The function of Nucleolus is to produce ribosomes and it contains DNA.
- Spherical shape
- Visible when cell is not dividing
It directs all cell activities
The nucleus is a dense structure that controls the whole cell.
It contains all of the cells DNA
The function of nucleolus is RNA synthesis
Functions of nucleus are:-
1.regulate cell cycles.
2.helps in transfer of characters from parents to offspring
3.it is the functional head of cell
It contains the DNA of a cell and is used for cellular reproduction. The nucleolus also contains RNA and is composed of proteins and nucleic acids.
Nucleous work in cell is like a power house.it the nucleolus control all the vital activities of cellit directly takes part in cell division and reproduction.it produces DNA &RNA
The center of a cell. It is a membrane that holds the chromatin (DNA)
The nucleus contains nearly all cells' DNA and with it the coded instructions for making proteins and other important molecules.
It controls what the whole cell does, it is like a main control
Nucleus is the solid part of a comet it is made of frozen gases,water vapor and dust particles
Nucleus is the master control of the cell
Control the metabolic activities of the cell.
The part of the cell which contains chromosomes
Controls what goes in and out
It is the most important part of the cell
In simple word we can say that the nucleus control all the activities of cell
All the functions of the cell are controlled by the nucleus.

It keeps everything running and makes sure that all the parts of the cell are doing there jobs
sort of like a soccer coach or a teacher or pricipel, or even presedent.
Control center of the brain
It controls all the cellular actions
The nucleus regulates all cell activities
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.
It tells the cell where to go and what to do...it's kind of like the "brain" of the cell if you like
The nucleus is the center of a cell and is in control of all cell activities. The two major
types of material within the nucleus: 1. Nucleoplasm 2. Chromatic.
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.
The functiOn Of the nucleus is tO send Out cOpies Of the blueprints fOr buildinG prOteinS, which in turn cOntrOL every aspect Of cellular activity. The nucleus present in it synthesizes RNA and ribOsOmal proteins
