Flashcards- Ch 12 Notes Part 1 Stages of Mitosis

Front

Stages of mitosis

Back

Prophase, Metaphase, Anaphase, Telophase

Front

What cell cycle phase is this cell in?

Back

Front

Describe what is happening to the DNA in prophase.

Back

During prophase, chromatin condenses, making chromosomes visible under a microscope.

Front

Describe what is happening to the DNA in interphase.

Back

During interphase the DNA is being copied/ replicated.

Front

Describe what is happening with the Centrosomes and Centrioles Movement in prophase.

Back

Centrosomes (Microtubule Organizing Centers) and centrioles separate and start to move to opposite sides of the nucleus during prophase.

Front

Formation of Spindle Fibers

Back

Spindle fibers form from Microtubule Organizing Centers (MTOC) during prophase. These fibers are made of microtubules.

Front

What phase are these cells in?

Back

prophase

Front

What happens to the nucleolus in prophase?

Back

Nucleolus breaks down/ disappears during prophase.

Front

What happens to the nucleus in prophase?

Back

Nuclear envelope breaks down into vesicles in late prophase.

Front

What happens whit the spindle fibers in prophase?

Back

Spindle fibers move towards centromeres of chromosomes and attach during prophase.
