Learning the Cell Cycle

In order for a cell to divide, it must complete 3 tasks. What are those three tasks?

• 1. Grow,

  2. Copy DNA,

  3. Split

• 1. Grow,

  2. Reorganize,

  3. Delete extra DNA

• 1. Maintain homeostasis

  2. Shrink smaller

  3. Delete unimportant parts of DNA

• 1. Grow

  2. Shrink

  3. Repeat

What are the TWO MAJOR phases of the cell cycle?

• G1 and G2

• S phase and Mitosis

• Interphase and Mitosis

• Cytokinesis and Prophase

What happens in G1 phase of the cell cycle?

• the cell grows physically larger and copies all of its organelles

• DNA replication

• Chromosomes line up in the middle

• Cell splits in half

During the S phase, the cell makes a complete copy of the _____ in its nucleus

Which phase is known as the second growth phase?

• G1

• S

• G2

• Interphase

Which phase is NOT considered part of interphase?

• G1

• Prophase

• G2

• S

What is the overall goal of mitosis?

• to make sure that each daughter cell gets a perfect, full set of chromosomes (DNA)

• to make sure each daughter cell only gets the part of the DNA it needs

• to make sure each daughter cell is unique

• to make sure each daughter cell is unlike any other

In which phase of mitosis do the chromosomes start to change from noodle shape to X shape?

• Metaphase

• Prophase

• Anaphase

• Telophase

In which phase of the cell cycle do all the chromosomes line up in the middle of the cell and attach to spindle fibers?

• prophase

• metaphase

• anaphase

• telophase

During which phase of the cell cycle do the spindle fibers begin to pull the chromosomes apart?

• prophase

• metaphase

• anaphase

• telophase
