The four nitrogenous bases that are present in DNA are adenine, guanine, thymine and cytosine. These nucleotides can be radiolabelled before the new DNA forms and the composition of specific nucleotide of DNA can be estimated.
During the experiment, research team found that the incorporation of radioactive nucleotides composition increase after the introduction of pathogen in the culture. This means that the cell starts producing more number of cell to fight against the pathogen. The infection of pathogen is mainly responsible for the division of lymphocytes more rapidly.

MPC stands for "marginal propensity to consume," which refers to a rise in consumer spending for every unit of income level achieved.
Marginal propensity to save (MPS) is the percentage of a person's income that they put away for savings for every unit that their income level rises.
Spending multiplier = Increase in income level for each unit increase in autonomous spending = 1/(1-MPC) = 1/MPS Spending multiplier = Increase in income level for each unit increase in autonomous expenditure. This is further explained below.
<h3>What is a multiplier?</h3>
Generally, the amount by which the return on investment is greater than the investment itself is referred to as the investment's return on investment (ROI).
In conclusion, Marginal propensity to save (MPS) is the percentage of a person's income that they put away for savings for every unit that their income level rises.
