Nucleotides can be radiolabeled before they are incorporated into newly synthesized DNA and, therefore, can be assayed to track

their incorporation. In a set of experiments, a student-faculty research team used labeled T nucleotides and introduced these into a culture of dividing human cells at specific times. Use the following information to answer the question below. The research team used their experiments to study the incorporation of labeled nucleotides into a culture of lymphocytes and found that the lymphocytes incorporated the labeled nucleotide at a significantly higher level after a pathogen was introduced into the culture. They concluded that __________.
a. their tissue culture methods needed to be relearned
b. infection causes lymphocyte cultures to skip some parts of the cell cycle
c. infection causes cell cultures in general to reproduce more rapidly
d. the presence of the pathogen made the experiments too contaminated to trust the results
e. infection causes lymphocytes to divide more rapidly

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.

Which of these is a polysaccharide? A. Lactose. B. Glycogen. C. Sucrose.
geniusboy [140]

cellulose is a polysaccharide.

A significant class of biomolecules is polysaccharides. They are large chains of monosaccharide molecules that are linked together. These intricate biomacromolecules serve as a vital energy source for animal cells and are a crucial part of plant cells' structural makeup. The nature of the monosaccharides determines whether it is a homopolysaccharide or a heteropolysaccharide.

A branching polysaccharide is a type of carbohydrate that is different from a linear polysaccharide, which is a straight chain of monosaccharides.

Organisms have this energy in reserve. The molecules are hydrophobic because water cannot enter them because of the many hydrogen bonds present. They permit adjustments to the concentration gradient, which affects how the cells absorb nutrients and water.
