U4 Formative FS24 - cell cycle, mitosis, cancer, & stem cells

Front

What is the name of the phase in the cell cycle where the chromosomes are separated to opposite poles of the cell?

Back

Anaphase

Front

What occurs during the S stage of interphase?

Back

The DNA is replicated.

Front

What is the structure that holds two sister chromatids together until they are separated during cell division?

Back

Centromere

Front

During which stage of mitosis do the nucleolus and nuclear membrane start to disappear?

Back

Prophase

Front

What is the primary reason muscle cells differ from blood cells?

Back

Different genes are activated in muscle cells than in blood cells.

Front

What are the main stages of the cell cycle?

Back

Interphase (G1, S, G2) and Mitosis (Prophase, Metaphase, Anaphase, Telophase).

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes and pull them to opposite poles of the cell.

Front

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

Back

The G1 phase is where the cell grows and prepares for DNA replication.

Front

What happens during telophase in mitosis?

Back

The chromosomes de-condense, the nuclear membrane re-forms, and the cell prepares to divide.

Front

What is cancer in terms of cell cycle regulation?

Back

Cancer is the uncontrolled division of cells due to mutations that disrupt normal cell cycle regulation.
