Nucleus Functions

Satisfactory Essays
The nucleus is one of the most important parts of any animal or plant cell. It has four really main functions and parts. It holds DNA in chromosomes, includes the nucleolus, controls protein synthesis, and lastly the nuclear membrane. This parts and functions really make up what we know as the nucleus. First, let’s begin with the DNA that the nucleus holds in chromosomes. This is a big factor in why the nucleus is such an important part of any animal or plant cell. These DNA polymer is a double helix made up of multiple nucleotides. Each nucleotide is either a guanine, adenine, thymine, and cytosine. Except only adenine will only bond with thymine, and guanine will only bond with cytosine. DNA also has a big role in the development of living…show more content…
The nucleolus is the biggest structure in any nucleus. The nucleolus is known for making and producing ribosomes. The nucleolus stores genes for pre-RRNA that make up a strong base for the nucleolus. The nucleolus also has many unique functions. These functions include assembly of recognition particles, changing and modifying RNA, and sensing stress on the cell. Another important function or part is the ability of the Nucleus to control protein synthesis. Protein synthesis is where cells make and generate new proteins. This function takes place mostly during translation and transcription, but takes place in the nucleus. In protein synthesis tRNA molecules are brought together and matched with an mRNA. Protein synthesis varies differently in plant and animal cells, but at the same time is very similar. Next, another important part of the nucleus is the nuclear membrane. The nuclear membrane is a lipid bilayer membrane that encases the contents of the nucleus including the the DNA, and the nucleolus in animal cells. The nuclear membrane has holes in it for materials and proteins to pass in and out of the nucleus. These holes also link the inner and outer membrane. Another important function that the nuclear membrane does is it keeps the contents of the nucleus completely separate from cells cytoplasm. Without the nuclear membrane the DNA would be at risk of the chemical reactions that happen in the
