S7L3a Part 2 Cell Cycle/Mitosis

Front

What happens to the DNA before cells can divide?

Back

It is replicated/duplicates.

Front

Why is DNA important?

Back

It provides the instructions/blueprint for a cell.

Front

What occurs during telophase in mitosis?

Back

2 new nuclei form.

Front

Why is metaphase important in mitosis?

Back

The DNA lines up in the MIDDLE so exact copies can be pulled to each side.

Front

What happens in prophase of mitosis?

Back

The chromosomes become visible; nucleus disappears; spindles form.

Front

What is the cell cycle?

Back

The series of events that take place in a cell leading to its division and duplication.

Front

What are sister chromatids?

Back

Identical copies of a chromosome, connected by a centromere.

Front

What is cytokinesis?

Back

The process where the cytoplasm of a parental cell divides into two daughter cells.

Front

What role do spindle fibers play in mitosis?

Back

They help separate the chromosomes during cell division.

Front

What is the function of the centrioles during mitosis?

Back

They help organize the spindle fibers.
