Nucleus Structure
What the parts of the nucleus?
Cell parts and function-I have always heard that the nucleus is the brain of the cell. But why is it the brain, and what are the major parts of the nucleus?
The nucleus is a large organelle. In fact, you can see the nucleus with a compound microscope.
Here it is inside a cheek cell.
I’m going to look at four main components of a nucleus and the role each part plays.
The nucleus is surrounded by a nuclear membrane. It is very similar to the cell membrane, and it is composed of two layers. It protects and houses the other parts of the nucleus.
You can also find ribosomes on the outside of the nuclear membrane.
Up next are nuclear pores. These are openings found on the nuclear membrane.
They allow items to move in and out of the nucleus. An e...

---TRANSCRIPT---
Thanks for stopping by, this is 2 minute classroom and today we are talking about the structure and function of the nucleus.
The nucleus sits in the center of eukaryotic cells and houses the DNA. It protects your genetic information and directs the synthesis of ribosomes and the expression of your genes. It’s also the location of transcription and DNA replication. You can think of it as the brain of the cell.
The nucleus has a very distinct structure.
It’s surrounded by a double membrane called the nuclear envelope which contains special nuclear pores through which ribosomes and RNA exit. This nuclear envelope protects the DNA from nuclease enzymes in the cell whose job it is to destroy nucleotides, and you don’t want your DNA destroyed. The DNA never leaves the nucleus for the same reason.
Within the nucleus there is a dark region called the nucleolus. This area is densely packed with RNA and proteins and is the location of ribosome assembly among other functions. Ribosomes have a big impact on cellular processes and I’ll create a separate video about ribosomes and link it here when it’s ready.
The nucleolus sits in the nucleoplasm, which encompasses the reamining contents of the nucleus. This is where the DNA is located. When the cell is getting ready to divide, the DNA forms chromosomes, these are structures you may be familiar with. Humans have 46 chromosomes in each cell.
However, most of the time the DNA is not in this chromosome structure, but is called chromatin, with the DNA being less compact and wrapped around special histone proteins.
If you are student interested in saving time in your studies, consider subscribing and hitting the bell to keep up with my content.
Here is a test prep playlist and some other videos you may enjoy. Thanks for watching, and I’ll catch you next time.

Cell parts and function-I have always heard that the nucleus is the brain of the cell. But why is it the brain, and what are the major parts of the nucleus?
The nucleus is a large organelle. In fact, you can see the nucleus with a compound microscope.
Here it is inside a cheek cell.
I’m going to look at four main components of a nucleus and the role each part plays.
The nucleus is surrounded by a nuclear membrane. It is very similar to the cell membrane, and it is composed of two layers. It protects and houses the other parts of the nucleus.
You can also find ribosomes on the outside of the nuclear membrane.
Up next are nuclear pores. These are openings found on the nuclear membrane.
They allow items to move in and out of the nucleus. An example would be the mrna. It would travel through a nuclear pore to leave the nucleus.
Nucleoplasm This is a gel-like material found inside the nuclear membrane. You will find the DNA suspended in the nucleoplasm
Nucleolus. This is almost like a nucleus inside the nucleus. It has a very high concentration of DNA,
It is also the site of transcription which is the starting point of protein synthesis.
This is how the nucleus controls the cell. It has all the information on how to make stuff like proteins inside the cell. These proteins are used for many purposes inside the cell.
Ribosomes are also made at the nucleolus
All eukaryotic cells have a nucleus and bacteria and other prokaryotic cells do not have a nucleus.

The cell nucleus is crucial to multicellular life, so you think science would have a good idea how it evolved. The truth is, we don't, but Scientists do have some theories, including invading giant viruses!

You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-biology/
In this video, we look at the structure and function of the nucleus. First we look at the role of the nucleus in protein synthesis. We then explore the structure of the nucleus including the nucleoplasm, the nuclear envelope and the nucleolus.
This video is aimed at the UK A Level Biology specifications. Students studying International A Level Biology will need to check their specification.
