Watch the full video of Nucleus Functions And Important Cell Parts
The function of the nucleus in the body is indeed very important, because the body itself performs all the functions in it at the same time. For example, the process of pumping blood, then sending orders from the brain, then producing urine to digest food. Everything was done at almost the same time.
And all the tasks that are carried out in the body can run smoothly at the same time thanks to the nucleus or cell nucleus. And also other organelles that work together to control the function of cells in the body.
For this reason, here we will provide a more complete discussion of the nucleus or cell nucleus, starting from its parts, characteristics and functions.
What is Nucleus? And the Parts
The nucleus or cell nucleus itself is an organelle that has a round shape but has a fairly large size. On the outside of the nucleus itself is surrounded by a protective layer or membrane.
And this cell nucleus consists of several parts, the following is an explanation:
1. Nuclear Envelope
The first part is the nuclear envelope which is the outermost part of the nucleus. This nuclear envelope itself surrounds all the outermost parts of the cell nucleus. And this part itself consists of two layers, the first is the outer layer and the second is the inner layer.
In the nuclear envelope there are pot pores whose size is approximately 100 nanometers. This section is the entry and exit of the molecule.
2. Nuclear Lamina
Next there is the nuclear lamina which is the layer under the nuclear envelope with a net-like shape. This layer itself is formed from a protein called lamin.
This section has the task of strengthening or supporting the nuclear envelope structure. Thus ensuring that the structure of the cell nucleus remains strong and sturdy.
This part of the nuclear lamina itself does not only contain lamin proteins but also contains other proteins that will help the nuclear lamina to work together with the layers inside the nuclear envelope.
The nuclear lamina will also work with proteins that have a fiber shape called the nuclear matrix. These fibers help the genetic material in the nucleus to work and do its job more efficiently.
The DNA in this nucleus will later become a unit called a chromosome. Each cell nucleus itself contains about 46 chromosomes.
Inside this chromosome not only contains a set of DNA but also contains protein. The combination of DNA and protein in this chromosome will later be referred to as chromatin.
Well, the DNS that is in this chromosome stores all the information about each individual characteristic. Such as hair color and type, eye color, skin color to height.
Inside the chromosomes are also stored information and also instructions regarding cell division, reproduction to the development of living things.
Nucleolus itself is one part of the cell nucleus which has a solid shape and does not have a protective layer or membrane on the outside. Inside the nucleolus contains RNA as well as protein.
In addition, this nucleolus has a duty as a regulator of riboso synthesis, but when the process of cell division occurs, the nucleolus will disappear. However, after the process is complete, the nucleolus will form again.
The last part is called the nucleoplasm which is part of the cell nucleus or nucleus with a gel-like shape. This section is between the layers of the nuclear envelope.
The nucleoplasm itself is also commonly referred to as the karyoplasm which has the task of being a protector or additional cushion for other parts of the cell nucleus so that these parts will not be damaged quickly.
In addition, the nucleoplasm also has the task of maintaining the shape of the cell nucleus or nucleus.
Characteristics of the Nucleus
The function of the parts of the cell nucleus and the cell nucleus itself does have a very crucial role for the survival of humans, including other organisms on earth.
Because if one of the functions of the nucleus is disrupted, the cell will not be able to survive properly. Thus making cells quickly experience damage which ultimately makes the body susceptible to dangerous diseases.
The nucleus itself has a different shape from other cells or organelles and the following are some of the characteristics of the nucleus:
- Has a round and oval shape almost like a cup.
- The nucleus is in the innermost part of the cell.
- It has a diameter of approximately 5 µm.
- Being the center of activity of the cell itself.
- The nucleus is covered by a double membrane, namely the inner membrane and the outer membrane.
Nucleus Functions and Full Explanation
You must already know that each organelle has a different role because the cell nucleus or nucleus itself has the main function, namely as an information center and control for all cell activities.
Simply put, this cell nucleus has a role that is almost similar to our brain. And the following is a complete explanation of the function of the cell nucleus or nucleus:
1. Duty to Store Genetic Information
The nucleus has the function of storing data and information regarding genetics because the nuclear membrane in the nucleus itself is able to maintain the DNA in it.
2. Can Control Cell Growth
Apparently the nucleus can not only control cell activity but another function or task of this cell nucleus is to regulate the growth of cells in our bodies.
Starting from cells that are dividing and cells that can only grow. Even cells that cannot divide are also under the control of this cell nucleus or nucleus.
3. Become a Replication and Transcription Place
For the function of this nucleus, it is actually quite clear that it exists and is owned by the nucleus or cell nucleus. Because the nucleus is where the replication process is carried out by DNA.
And when the replication process carried out by the DNA itself is complete, then the next process of mitosis will take place.
4. Able to Control Metabolism
The last main function of the cell nucleus or nucleus is to control metabolic processes. This process can take place in the cell nucleus because of a process capable of producing protein.
This process also occurs due to transcription and translation in the nucleus and cell nucleus.
The final word
Of the various functions that exist in the nucleus, it’s no wonder this organelle is one of the most important in the body. Even considered prominent and most vital in comparison with other types of organelles in our bodies.
Moreover, the cell nucleus itself contributes approximately 25 percent of the cell volume, which makes the function of the nucleus very important for our bodies.
