Why are there nucleotides (A, T, G, and C) in the master mix? What are the other components of the master mix, and what are thei
tankabanditka [31]

Answer: Nucleotides are the monomers used for DNA synthesis. The mix also contains a template, DNA taq polymerase, buffer, reverse and foward primer and magnesium ions.

Explanation:

A PCR master mix is a premixed solution that has all of the components for a Polymerase chain reaction (PCR). This reaction is a laboratory technique that amplifies small fragments of DNA into millions of copies.

The master mix used for that contains dNTPs (nucleotides). In the DNA there are four types of nucleotides that are differentiated by the nitrogen base they have: adenine (A), guanine (G), cytosine (C) and thymine (T).

<u>Since nucleotides are the monomers that make DNA, they are found in the mix because they are the material for DNA synthesis.</u>

The reaction mixture also requires;

  • DNA template, the sequence of DNA to be amplified
  • DNA taq polymerase, a heat resistant enzyme that assembles nucleotides into a new DNA
  • Salt buffer, for an optimum ionic environment and pH
  • Oligonucleotide primers (reverse and foward), pieces of DNA complementary to the template. Each hybridizes with one of the DNA chains.
  • Magnesium ions, a catalyst required by DNA polymerase to work

Two primary hormones that are secreted by the pancreas are:

Gastrin: This hormone helps in digestion by stimulating certain cells in the stomach to produce acid.
