Stem Cells & Meiosis

Which of these is the correct definition of meiosis?

• Dividing the nucleus of a cell

• Making enzymes

• Making gametes

• Making mRNA

Which stage in Meiosis is pictured?

• G₂

• Cytokinesis II

• Prophase I

• Interphase II

What do you call it when cells begin to develop structures & functions that are different from other cells in the organism?

• Mitosis

• Differentiation

• Protein synthesis

• Meiosis

Which of these is true of meiosis? Click ALL that apply.

• There are four cells at the end

• The end cells are identical to the parent cell

• The chromosomes will have swapped chunks

• The end cells have half as much DNA as the parent

How are stem cells different from other cells in an organism?

• They have less DNA

• They have more DNA

• They can make enzymes from DNA faster

• They can read all the DNA

During meiosis, cells basically go through the same stages as mitosis twice (although there are differences). Which of this has those stages in the correct order?

• prophase, metaphase, anaphase, telophase

• anaphase, metaphase, prophase, telophase

• telophase, prophase, metaphase, anaphase

• metaphase, anaphase, telophase, prophase

What are gametes?

• Organelles that aid in cell division

• Polymers that build compounds

• Reproductive cells

• Chromosomes that carry the same genes

Which stage of meiosis is pictured?

• Anaphase II

• Metaphase II

• Cytokinesis I

• Telophase I

During which stage of meiosis does crossing over occur?

• G₂

• Cytokinesis I

• Metaphase I

• Prophase I

Why do complex organisms (like humans) need to undergo differentiation? Click all that apply.

• To be able to grow

• To develop different tissues & organs

• There are too many jobs for every cell to be able to do all of them

• To be able to heal injuries
