Answer:
when G1/S cyclin-CDK is activated. Expression of G1/S cyclins is regulated by E2F proteins
Explanation:
I've found this on Google
Commitment to cell division occurs at Start when G1/S cyclin-CDK is activated. Expression of G1/S cyclins is regulated by E2F proteins in conjunction with pRB proteins.. Mitogens stimulated cell division by increasing the amount of G1 cyclins.
During DNA replication, DNA helicase enzymes move in a range of 
along the DNA.
<h3>
What are the benefits of DNA helicase?</h3>
Helicase enzymes are found in all living organisms, from bacteria to humans. They are required for replication and repair of DNA.
Helicases are enzymes that can unwind double-stranded DNA. They are found in all living cells and they play a key role in gene expression, replication and repair.
Helicases are also used for other purposes such as the production of recombinant proteins and the isolation of DNA from cells.
The helicase enzymes have many benefits for humans. For instance, they can break down the DNA from a cell to extract information about it. They also enable us to duplicate our genes so that they are preserved during cell division.

The answer is B. They are in control of the experiment, they can change it the variables to better help the experiment.
Its explain why mitochondria in animals and plastids in plants have its own DNA and double membrane. The theory postulates that this is due to a symbiotic relationship that began with the history of life when protists probably engulfed bacteria (most probably by phagocytosis). The bacteria offered energy while it was sheltered. The relationship evolved to become facultative.
There are choices for this question namely:
<span>1. Initiate oxygen therapy
2. Assess for a pleural friction rub
3. Obtain a chest x-ray film immediately
4. Place the client in a fowler's position
</span>
The correct answer is that the nurse should "place the client in a fowler's position". The fowler's position is a position wherein the head and chest of the patient is elevated more than the lower extremities. In a patient with heart failure with tachypnea and bilateral crackles, the nurse should suspect pulmonary edema. By placing the patient in a fowler's position, the edema fluid in the lungs will gravitate towards the lower extremities, reducing pulmonary edema and reducing symptoms of dyspnea and tachypnea.
