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.

Answer:
Nerve agent
Explanation:
A nerve agent is a chemical in which on exposure to humans affects the functioning of the nervous system. These chemicals are known to disrupt the process by which messages are transferred to the organs from the nerve. This disruption occurs by blocking the activity of acetylcholinesterase, which is responsible for the catabolism of a neurotransmitter, acetylcholine.
On exposure to a nerve agent, the muscles of the body become paralyzed and early symptoms is production of excess mucous such as in runny nose, pupil constriction and also difficulty in breathing.
These agents are sometimes used in chemical warfare. Examples include sarin, tabun etc.
Yes, but only if the chromosomes are paired in the right ways. tetrad development in late prophase.
<h3>How does DNA function? Why does it matter?</h3>
The biological instructions that give each species its distinctiveness are found in a substance known as deoxyribonucleic acid (DNA). Adult organisms reproduce by transmitting their DNA and the genetic information it carries to their progeny.
<h3>What is the purpose of a person's DNA?</h3>
Genes, which are a component of DNA, are the building blocks of all living organisms. DNA's capacity for recurrent self-replication is its most significant property. DNA must be replicated in order to create new cells, convey genetic information from one generation to the next, and act as a code for the RNA (ribonucleic acid) needed to make proteins.
