Answer:
e. infection causes lymphocytes to divide more rapidly
Explanation:
The cell cycle includes interphase and M phase which in turn together produce daughter cells from the existing parent cells. DNA replication occurs during the S phase of interphase to ensure that the daughter cells obtain the identical DNA present in the parent cell.
Lymphocytes are one of the types of white blood cells and are involved in cell-mediated and antibody-mediated immune responses. These cells are present in the blood as well as in lymphatic tissues. During the given experiment, lymphocytes exhibited a higher rate of incorporation of labeled nucleotide after the introduction of a pathogen in the culture. This suggests that the introduction of pathogen triggered the cell division in lymphocytes to produce more lymphocytes to fight the infection.
DNA polymerases add nucleotides to the 3′ end of a polynucleotide chain. ... To initiate this reaction, DNA polymerases require a primer with a free 3′-hydroxyl group already base-paired to the template. They cannot start from scratch by adding nucleotides to a free single-stranded DNA template.
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
The correct answer is all of the above
Answer: C) Perform the jaw-thrust airway maneuver.
Explanation:
The patient is suffering from breathing problem and her airways must be opened to allow breathing.
The jaw-thrust airway maneuver must be performed on elderly women. This is because of the fact that it is an ideal technique for patients who are suspected of having head or neck injury. This is done for patients who are unable to maintain their own airway during injury. The jaw-thrust maneuver is done by placing the index finger to lower jaw upwards and thumb is pulled down on the chin to open the mouth this will help to open the airway.
