A cell biologist carefully measures the quantity of DNA in grasshopper cells growing in cell culture. Cells examined during the G1 phase of the cell cycle contained 200 units of DNA. What would be the amount of DNA in one of the grasshopper daughter cells right after cytokinesis?

200 units

Explanation:

Cell cycle refers to the series of events that occurs throughout the division of a cell. Mitosis is the division used during cell growth. Mitosis consists of the Interphase stage and the Mitotic phase. The interphase stage is made up of the G1, S and G2 phases in that order. The genetic material (DNA) of the cell replicates during the Synthesis (S) phase.

Hence, this means that the DNA of grasshopper cells in the culture observed during the G1 phase will enter the S phase and replicate i.e. 200 units will form 400 units.

The cell go ahead to undergo nuclear division during the anaphase of the mitotic phase. Hence, each pole of the cell will contain 200units of DNA each. During Cytokinesis, the cytoplasm of the cell divides and the contents of the opposite poles becomes a new daughter cell. Each daughter cell will therefore contain 200 units of DNA each.

explanation:

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
