Review of Cell Cycle

I play music at the club

Name the 3 Parts of the Cell cycle

1) Interphase: • Gap1: growing, carying out normal cell

function. • Synthesis: copies its DNA in preparation for

cell division• Gap2: Cell prepares for division of the nucleus

2) Nuclear division: Mitosis3) Cytokinesis

Page 3: Review of Cell Cycle I play music at the club. Name the 3 Parts of the Cell cycle 1) Interphase: Gap 1 : growing, carying out normal cell function. Synthesis:

Name and describe the 4 phases of mitosis ( in order)

Prophase: • Nuclear membrane breaks down• Nucleolus disappears• Chromosomes coil and thicken• Spindle begins to form between the centrioles

Page 4: Review of Cell Cycle I play music at the club. Name the 3 Parts of the Cell cycle 1) Interphase: Gap 1 : growing, carying out normal cell function. Synthesis:

Metaphase:• Chromosomes attach to the spindle and align

along the equator of the cell.

Anaphase• Microtubules shorten, moving chromosomes

to opposite poles.

Page 5: Review of Cell Cycle I play music at the club. Name the 3 Parts of the Cell cycle 1) Interphase: Gap 1 : growing, carying out normal cell function. Synthesis:

Telophase:• Chromosomes reach poles of cell• Nuclear envelope re-forms• Nucleolus reappears• Chromosomes decondense

What is a sister chromatid?

• Sister chromatids are structures that contain identical copies of DNA and are attached together with a centromere

What is cytokinesis?

Cytokinesis: a process that divides the cytoplasm which results in two cells, each with identical nuclei.

Page 8: Review of Cell Cycle I play music at the club. Name the 3 Parts of the Cell cycle 1) Interphase: Gap 1 : growing, carying out normal cell function. Synthesis:

• Centromere: joins the two sister chromatid• Spindle: The apparatus that moves and

organizes the chromosomes before cell division.

• Chromosome: A single copy of DNA• Chromatin: All the chromosomes in a relaxed

state (during interphase)• Sister chromatids: two copies of DNA
