During which part of the cell cycle do gene mutations occur?

s2008m [1.1K]

Answer:

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). ... Together, the transcription factors and RNA polymerase form a complex called the transcription initiation complex.

What chromosomes are found in body cells but not sex cells?

Leni [432]

None, egg cells don't have chromosomes. No, sex cells do have chromosomes. meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes–one homolog of each pair. This is the haploid number.

Neurons in the parasympathetic pathway use which neurotransmitters?

Kay [80]

<h2>Acetylcholine</h2>

Explanation:

Acetylcholine is a chemical that is found between the nerve synapses, or gaps, between nerve cells. When activated, it causes the contraction of skeletal muscles and activates glandular functions in the endocrine system. Think of acetylcholine as a mailperson; residents cannot receive their mail until he or she comes and delivers it to the mailbox. Like mailpersons who deliver the mail and move on to the next house, acetylcholine acts quickly and does not hang around. As a result, acetylcholine is rapidly broken down by another chemical substance called cholinesterase.
Acetylcholine was the first neurotransmitter scientists discovered, as well as the most abundant neurotransmitter in the body. A neurotransmitter is a chemical that is released by a neuron, or nerve cell, that sends a signal to another neuron across a synapse. The neurotransmitter binds to receptors to affect how the signal is received. The purpose of the neurotransmitter is to either amplify or inhibit the signals sent between the neurons.
Acetylcholine plays an important role in the signal of muscle movement, sensation of pain, learning and memory formation, the regulation of the endocrine system and rapid eye movement (REM) sleep cycles.

Why is cytokinesis an important part of the cell division? how can cytokinesis help us?

Sliva [168]

Answer:

1. Cytokinesis represents the major reproductive procedure of unicellular organisms, and it occurs in the process of embryonic development and tissue growth and repair of higher plants and animals.

2. Cytokinesis performs an essential process to separate the cell in half and ensure that one nucleus ends up in each daughter cell. Cytokinesis starts during the nuclear division phase called anaphase and continues through telophase.
