Question

Identify which phase of the cell cycle is represented by each region. the regions represent the same cell cycle phases in both histograms.

Answer 1

The cell cycle consists of interphase and the mitotic phase. Interphase is divided into G1, S, and G2 phases. The mitotic phase includes mitosis and cytokinesis. During interphase, the cell grows and performs its normal functions, while during the mitotic phase, the duplicated chromosomes are separated into daughter cells.

Step-by-step explanation:

The cell cycle consists of two major phases: interphase and the mitotic phase. Interphase is further subdivided into three periods: G1, S, and G2. During interphase, the cell grows and performs normal functions. The S phase is when DNA replication occurs, resulting in duplicated chromosomes. The G1 and G2 phases are periods of growth and preparation for cell division.

The mitotic phase of the cell cycle consists of mitosis (cell division of the nucleus) and cytokinesis (division of the cytoplasm). During mitosis, the duplicated chromosomes condense and segregate into daughter nuclei. Cytokinesis occurs after mitosis and involves the separation of the cell into two daughter cells.

Answer 2

The answer is region a as G1, region b as S and region c as G2. In addition to biology, the region c shows the population of cells with the highest amount of the DNA per cell. The DNA content per cell changes as the S phase progresses so the cells in S phase have a range of fluorescence levels. The G1 phase of the cell cycle has the greatest number of cells.
