The number of chromosomes in a female
scorpion’s egg cells have half as many chromosomes as compared in her body
cells. Chromosome is a single long molecule of DNA wound around proteins called
histones. It is
made up of DNA wrapped around proteins.
The primary function of the Calvin cycle is to change carbon dioxide into usable energy known as glucose. So Option A.
Brainsliest would be appreciated.
Answer: The correct answer is A. During this time, cells take in nutrients, which are important for energy, growth, and repair of the cell.
Interphase is the first phase of the cell cycle. During this phase, the cell takes in nutrients, which are important for energy, growth, and repair of the cell.
In other words, cell prepares for division by growth, synthesizing essential proteins, and duplicating the DNA. This phase occurs prior to cell division.
This phase is primarily divided into G1, S, and G2 phase. G1 and G2 are the gap phases during which cellular growth and synthesis of essential proteins take place.
S phase ( synthesis phase) includes the duplication of the DNA so two identical cells are obtained after cell division.
Thus, the correct statement, which describes the interphase is A.
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 prevailing wind direction is West, even though natural wind direction is East. The West winds prevail because they are much stronger. The way this works is that the San Francisco Bay water is a constant cool temperature (around 50-60 degrees).
