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:
B
Explanation:
Emergency Medical Technicians (EMT) are responsible for offering basic care at a scene of incident while the patient is being taken to hospital.
They perform emergency medical assistance such as CPR and wound bandaging.
They are expected to offer quick reaction and and competent care since peoples lives depend on them.
However since they are not expected to go beyond or above their scope of functions since they are not trained doctors.
Answer:
The correct answer is A. Cells are the basic unit of life.
The DNA controls the cell's activities. It is usually found in the nucleus.
I also think it should be B
