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

Infection causes lymphocytes to divide more rapidly

Explanation:

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 Infection causes lymphocytes to divide more rapidly. The pathogen causes infection and thus the it was found that the lymphocytes incorporated the labeled nucleotide at a significantly higher.

. He concluded that infection contributes to a more rapid division of lymphocytes

Explanation:

The team of researchers used their studies to investigate the integration of marked nucleotides into lymphocyte culture and noticed that lymphocytes integrated the labeled nucleotide at a higher level after introduction of a pathogen into the culture. He concluded that infection contributes to a more rapid division of lymphocytes.
