Answer:

By forming chromatin and in the condensed form of chromosomes

Explanation:

The human genome contains around 3 billion base pairs which are located in the nucleus of all cells. In order to accomodate such large genomic information, DNA is maximally supercoiled during mitosis and meiosis processes to form condensed structures called chromosomes. Humans have 23 pairs of chromosomes per somatic cell. The supercoiling process is assisted by a family of proteins called histones, which interact with DNA and regulate its conformation. The complex between DNA and histones within the nucleus is called chromatin. When chromatin is supercoiled it form chromosomes (in eukaryotic cells).

What is the chemical composition of Glycocalyx?
ale4655 [162]

The chemical composition of glycocalyx is sugar and protein.

<h3>What is the glycocalyx?</h3>

The envelope formed by <em>glycoproteins, glycolipids and hyaluronic acid</em> located in the cell membrane is known as glycocalyx. This component works as a <u>mechanical cell protection</u> thanks to its composition, it also allows <u>cell adhesion</u> and <u>hormonal reception</u> by giving it a suitable environment for this reception.

The glycocalyx is not only seen in eukaryotic cells, but also in prokaryotic cells or in bacterial cells. Each type of cell has its different conformation of the glycocalyx, this <em>depends on its individual need</em>.

Therefore, we can confirm that the chemical composition of glycocalyx is sugar and protein.
