Mitosis

Cell Cycle

• •Interphase

  •Prophase

  •Metaphase

  •Anaphase

  Telophase 

Stage 1- Interphase

• žLongest part of cell life

• žCell carries out normal activities

• žDNA in long strands called chromatin

• žCentrioles

  as a pair

Late Interphase

• Chromatin doubles to form •chromosomes (# doubles)

• •Other cell parts also double

• •Editing of DNA to repair errors

Multiple Choice

The cell spends most of it's life in ________________.

• mitosis
• cytokinesis
• Interphase
• None of the above

Multiple Choice

Humans have ________ pairs of chromosomes.

• 21
• 23
• 46
• None of the above

Multiple Choice

Before cells can divide, what must be copied?

• mitochondria
• cytoplasm
• DNA
• Cell Wall

Stage II- Mitosis

• Prophase

• Centrioles (or poles) appear and begin to move to opposite end of the cell. Spindle fibers form between the poles

• •Chromosomes coil and become visible

Multiple Choice

During which stage of mitosis do spindle fibers form, chromosomes appear, and nuclear materials disappear?

• Prophase
• Metaphase
• Anaphase
• Telophase

Multiple Choice

What phase of Mitosis is the picture showing?

• Interphase

• Prophase

• Telophase

• Metaphase

Multiple Choice

What are the "X" shaped things in the drawing.

• PMATs

• Chromosomes

• Ribosomes

• Telophase

Metaphase

• Chromosomes line up in the middle of the cell on the spindle fibers

Multiple Choice

what is this phase

• prophase

• metaphase

• anaphase

• teloophase

Multiple Choice

what is this phase?

• metaphase1

• antiphase

• metaphase2

• telaphase

Anaphase

• Chromatids (or halves of chromosomes) separate and begin to move to opposite ends of the cell

Telophase

• •Chromatids finish separating.

• •Nuclear membrane reforms

• •Chromatids unwind and become chromatin.

Cytokinesis

•Cytoplasm and cell organelles divide evenly

•

•Two new cells are formed

Multiple Choice

What is the image above:

• Chromosome

• Chromotid

• Centromere

• Centriole

Multiple Choice

What is the purpose of mitosis?

• To increase the surface area of a cell
• To allow cells to divide for growth, repair, and renewal
• For increasing genetic variation within a species
• To allow for DNA replication and protein synthesis
