So, we've replicated DNA, now what?!

Nuclear Division - separates replicated DNA

​Purpose of Mitosis

M - Phase (Mitotic)

​The 4 stages of Mitosis

Stage 1 - Prophase
Stage 2 - Metaphase
Stage 3 - Anaphase
Stage 4 - Telephase

What are your observations about what is happening in this image?

Don't worry about the vocabulary for now!

​

Let's talk

​Write this under the Prophase image

​1. DNA condenses
2. Nucleus disappears
3. Spindle fibers attach to DNA

Prophase

What are your observations about what is happening in this image?

​

Talk to your partner

Spindle fibers push chromosomes to the middle

​

Metaphase

​An easy way to remember the name of the phase is to memorize the following

Chromosomes Meet in the Middle.

What are your observations about what is happening in this image?

​

Talk to your partner

Chromosomes are pulled away or apart.

​

Anaphase

What are your observations about what is happening in this image?

​

Talk to your partner

Two nuclei form around separated DNA.

​

​Telophase
