What purpose does isopropyl alcohol serve in the process of dna extraction?

Biology
1 answer:
4vir4ik [10]3 years ago
5 0

Answer:

The process of extracting the DNA is a very complex, time taking and tedious task. It needs lots of technical knowledge in order to extract DNA.

There are various chemicals used during the process of DNA extraction. The use of isopropyl alcohol is to precipitate the DNA.

This precipitation makes the DNA visible as it is clumped together. Then it becomes easy for the long strands of DNA to wrap around the stirrer when swirled at the interface between two layers.

The answer to this question would be labile.

A permanent cell is the one that will not divide after fully developed. This includes the heart and brain cells. That is why when these organs damaged there will be a permanent loss of function.
Stable cell only divides in some occasion. The example would be liver cells or kidney cells.

aniked [119]

Answer:

B (active transport using ATP)

Explanation:

Movement of substances normally occur in the direction of concentration gradient/difference i.e. the difference in concentration of a substance across a membrane. Letting molecules diffuse or pass down their concentration gradient does not require energy but pumping those molecules against gradient requires energy in form of Adenosine triphosphate (ATP). This process is called Active transport.

In order to perform certain cellular processes, cells need to move substances from their surroundings into the cell across their cell membrane. Moving this substances against the concentration gradient between the cell membrane and its extracellular fluid requires energy (ATP).

An example is the sodium-pottasium pump employed by animal cells in which they expend energy to move K+ molecules into the cell and Na+ molecules outside the cell against the concentration gradient of their cell membrane and extracellular solution.

VMariaS [17]

The third phosphodiester bond of ATP is broken mostly. The rest of the molecule is called Adenosine Diphosphate or ADP.

<h3><u>Explanation:</u></h3>

For knowing the answer, we need to know the structure of ATP first. ATP or the Adenosine Triphosphate is also called the energy currency of living cell. It has two components -

A. Adenosine which is actually an Adenine nitrogen base attached with a ribose sugar molecule.

B. Phosphate molecules.

The structure of Adenosine Triphosphate is a ribose sugar which is attached with one adenine molecule with which one phosphate ion is attached and the rest of the phosphate ions are attached with the phosphate one after the other.

Ribose - Adenine - Phosphate - Phosphate ~ Phosphate.

The last phosphodiester bond between the two phosphates is the most energetic bond containing maximum of the energy. This bond is broken during the metabolic processes to supply energy to the processes.
