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
Answer: The correct option is B.
B)the work to do the job is made easier
Explanation:
The work to do the job is made easier because it becomes easy to move object on high elevation, the sloping surface of the inclined plane support and hold part of the object weight. It then require little force or work to move the object up the hill compare to straight up height.
Pioneer species, I think.
Answer:
A Starfish is Triploblastic meaning they consist of three germ layers. Hydra are diploblastic meaning they consist of only 2 germ layers.
