The Y chromosome likely contains 70 to 200 genes that provide instructions for making proteins. Because only males have the Y chromosome, the genes on this chromosome tend to be involved in male sex determination and development.
<h3>What is a chromosome?</h3>
A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule. These chromosomes exhibit a complicated three-dimensional structure that is crucial for controlling transcription.
Under a light microscope, chromosomes are typically only discernible during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form).
Prior to this, each chromosome undergoes a process known as chromosome duplication (S phase), during which a centromere connects both copies, forming either the X-shaped structure (if the centromere is situated equatorially) or a two-arm structure (if it is situated distally) depending on where it is situated.

<h3>What are biomolecules?</h3>
Biomolecule, also known as biological molecules are many of the numerous substances produced bills of carbohydrate living organisms. These biomolecules have an extremely wide range of structures and sizes. They also perform a wide range of functions. The four major types of biomolecules are lipids, carbohydrate, proteins and nucleic acids.
- Nucliec acids form acids from the genetic material of the organisms.
- Carbohydrates and fats are used for the synthesis of energy.
- Proteins are used for structural and functional roles in the body.
Therefore, this is a correct statement.
