<u>Answer</u>:
<em>Sodium potassium pump works by following several steps.
</em>
<u>Explanation</u>:
<em>1. Carrier protein binds three molecules of Na+
</em>
<em>2. ATP is split, phosphate bonds to carrier.
</em>
<em>3. Carrier protein changes shape, and deposits Na on the outside of the cell.
</em>
<em>4. Carrier binds two molecules of K
</em>
<em>5. Phosphate is released.
</em>
<em>6. Potassium is released inside the cell
</em>
Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.
It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.
<em>Thus it is an active transport mechanism.
</em>
Answer:
Explanation:Ss
Because
The gene snails of a population consists of all the copies of all the genes in that population.
Hershey and chase have concluded that DNA is not protein it was the genetic material.
Explanation:
Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.
The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.
The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.
<em>DNA</em><em> </em>is what carries the genetic code for living organisms it contained in the nucleus of cells.
Hope that helps :)
