Answer:
The answer is given below.
Explanation:
A tiny difference in a distant enhancer make a blond through DNA Looping.
DNA Looping can bring the enhancer bound by an activator physically closer to the promoter even if the enhancer is located far away along the DNA molecule.
DNA Looping.
When a protein or a set of complex proteins binds to 2 different sites of DNA simultaneously while looping out the interfering DNA.
Important of DNA Looping
- It regulates metabolism of DNA
- it is involved in transcriptional initiation of prokaryotic operons.
Answer:
The two types of cells that never go through cell division once fully formed are nerve cells and muscle cells.
Explanation:
The nerve cells and the muscle cells not undergo cell division after formation, because they can never re grow or cannot be repaired once they are mature. We should take good care of it once they are matured. They just under division from being baby to teenagers after that they stop undergoing cell division. This is true for both elephants as well as human beings. This thing is also applicable in case of bones.

How does molecular size affect to the permeability
of the membrane to that molecules?
So you will try to find out how many
molecules of each kind pass through the membrane per time unit. If molecules
pass faster, it’s highly permeable to that material. Some molecules may not
pass at all, so then it’s not permeable to that material. Then you can put the materials
in order from the lowest to the highest permeability. You can also try to find
a mathematical formula that shows how permeability increases or decreases as size
increases (usually it decreases). Exel is usually helpful to find that formula:
you can make a plot and see if it is linear, exponential, potential, etc. There
are other softwares with a larger variety of graph options tan Excel.
