The data in the table were obtained from a study of the length of time spent in each phase of the cell cycle by cells of three eukaryotic organisms designated beta, delta, and gamma.
Which of the statements is the best explanation for the difference between time spent in S phase by beta and gamma?
A) Gamma contains more DNA than beta.
B) Beta and gamma contain the same amount of DNA.
C) Beta cells reproduce by binary fission and gamma cells reproduce by mitosis and cytokinesis.
D) Beta is a plant cell and gamma is an animal cell.

Quizplus · Accepted Answer

Gamma spends more time in the S phase than beta, which suggests that gamma likely has more DNA to replicate, requiring more time for DNA synthesis.
