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:
e. Genes and the environment affect antipredator behavior
Explanation:
Based on the data that was derived from the study we can conclude that Genes and the environment affect antipredator behavior. This is because regardless of the difference in the environment they were reared in both groups fled from the predator which is a genetic trait that has been passed down from generation. Yet, the group reared in low-temperature conditions fled sooner than those reared in high-temperature conditions meaning that the environment has affected the survival and antipredator behavior of the spiders.
When we say biotechnology, this is when biological resources are being utilized for industrial and other purposes. And if we consider the benefits and impacts of applying this to clean those polluted water systems, the most likely impact would be, it will be harmful to sewage treatment plants. The answer is D.
