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.
