Cell Cycle and Mitosis

Front

What is the result of mitosis in a human diploid (2n) cell containing 46 chromosomes?

Back

Mitosis results in the formation of two diploid daughter cells, each containing 46 chromosomes.

Front

What happens to the nuclear envelope during metaphase?

Back

The nuclear envelope disappears during metaphase.

Front

What phase of mitosis is characterized by the separation of sister chromatids?

Back

Anaphase is the phase of mitosis where sister chromatids are separated.

Front

In which phase of the cell cycle does a cell have half as much DNA as other cells in a mitotically active tissue?

Back

Cell A is most likely in the G1 phase of the cell cycle.

Front

What process does NOT occur during mitosis?

Back

Replication of the DNA does NOT occur during mitosis.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are G1, S (synthesis), G2, and M (mitosis).

Front

What is the significance of the G1 phase in the cell cycle?

Back

The G1 phase is significant for cell growth and preparation for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in two sister chromatids for each chromosome.

Front

What is the role of the spindle apparatus during mitosis?

Back

The spindle apparatus helps to separate the sister chromatids and pull them to opposite poles of the cell.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells contain two sets of chromosomes (2n), while haploid cells contain one set of chromosomes (n).
