Why are cells in the brain and spinal cord irreplaceable?

Biology
1 answer:
solniwko [45]3 years ago

Answer:

see the answer below

Explanation:

<em>The cells of the brain and spinal cord are irreplaceable because these cells do not undergo cell divisions like some other cells of the body.</em>

<u>Through cell division of the vegetative cells, damaged cells of the body are replaced by new cells. The cells of the brain and spinal cords however are special cells that will not divide under ordinary conditions. Hence, when there is any form of damage, there are no new cells to replace the damaged cells.</u>

Answer:

The three processes from left to right are:

<u>Replication</u>   DNA  <u>Trancription</u>  RNA  <u>Translation</u> Protein

Explanation:

The process in question in the diagram is called the central dogma of life which describes the flow of genetic information from DNA to RNA to Protein. The three processes involved are:

  1. DNA Replication
  2. Transcription
  3. Translation

DNA Replication:

DNA replication is the process by which DNA makes a copy of itself. Replication of DNA is semi-conservative. this means that each new helix is a combination of an old (parent) strands and a new (daughter strand). The parental strand is used as a template to generate a complementary daughter strand.

Transcription:

Transcription is the formation of an RNA transcript of the DNA template. This process yields a mRNA that is further used as a code to manufacture proteins in the process of translation.

Translation:

Translation decodes the mRNA formed in transcription to generate proteins with specific amino acid sequence.

In virto fertilization form of assisted reproductive technology.

<h3>IVF: Is the process painful?</h3>

It is comparable to a pap smear or even a vaginal ultrasound appointment. During this technique, an embryo transfer catheter and ultrasound guidance are used to transfer one or more embryos to the uterus. The entire operation will be visible to you on an ultrasound screen. This procedure is painless.

<h3>What distinguishes IVF from in vitro fertilization?</h3>

An IVF procedure involves surgically removing a woman's eggs from her ovaries and fertilizing them in a lab with sperm from a male partner or a sperm donor to produce embryos. (The term "in vitro" refers to the act of fertilizing an egg in a laboratory dish and is derived from the Latin meaning "in glass").
