10.2 Study Guide

Question 1

The order and events of the stages of mitosis (prophase, metaphase, anaphase, telophase, cytokinesis)

Answer 1

Prophase: Chromation condenses into chromosomes
Metaphase: Chromosomes align at the center of the cell
Anaphase: Sister chromatids seperate and move to opposite ends
telophase: Spindle fibers disapear, and cytokineses starts
cytokenesis: The cyptoplasm divides, forming daughter cells

Question 2

How a cell looks in each stage of mitosis

Answer 2

Prophase: Circle with nucleus
Metaphase: chromosomes in the middle of circle with spindle fibers
Anaphase: Those chromosomes are pulling apart going to opposite ends of cricle
Telophase: Two new circles

Question 3

Definitions and examples of multipotent, pluripotent, and induced pluripotent stem cells

Answer 3

Multipotent: Having the ability to differentiate into multiple different cells within a specific type ex Neural stem cells
Pluripotent:Cells that have the potential to differentiate into many cells, but not all cell types.
Induced Pluripotent: Adult stem cells that have been genetically reprogrammed.

Question 4

What causes specialized cells to be different from each other

Answer 4

They are different from each other by proteins and that they have different functions.

Question 5

Compare the parent cell to the daughter cells after mitosis

Answer 5

They are a replicate of the parent cell

Question 6

Explain how all of your body cells have the same genetic code but different functions

Answer 6

They express different sets of genes

Question 7

Explain the role of transcription factors in cell differentiation

Answer 7

They act as switches regulating gene expression, determining whether proteins can bind.
