Why is heating and cooling necessary when doing the pcr method?

Biology
1 answer:
pav-90 [236]3 years ago
4 0

A PCR is used to amplify DNA. The heating breaks the hydrogen bonds and ensures that the double-stranded DNA helix is melted such that the two strand separate. The cooling ensures that the introduced DNA primers bind with the single strands so that elongation of the chain (to form a new double helix) can be possible by DNA polymerase.

How does the purpose of the Kerbs cycle differ from the purpose of the cleaving cycle
lukranit [14]

Answer:

Both the pathways produce energy for the cell, where Glycolysis is the breakdown of a molecule of glucose to yield two molecules of pyruvate, whereas Kreb cycle is the process where acetyl CoA, produces citrate by adding its carbon acetyl group to oxaloacetate.

Explain how the terms oxidation and reduction apply even when there is only a partial shift of electrons between atoms linked by
aliina [53]

Explanation:

In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.

Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.

Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.

Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.

Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.

  • Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
  • This leaves a partial negative charge on it.
  • The other electron then becomes partially positively charged.
  • We can then say, the more electronegative specie undergoes reduction.
  • The less electronegative one undergoes oxidation.
