Understanding Metaphase in Mitosis

The video tutorial from MooMooMath and Science explains the metaphase stage of mitosis, one of the four stages of cell division. It describes how sister chromatids align in the cell's center, the role of spindle fibers, and the importance of the spindle checkpoint to ensure even chromatid distribution. The video also briefly covers prophase, where chromatids condense into chromosomes, and concludes with a transition to anaphase. The tutorial emphasizes understanding the cell cycle and encourages viewers to subscribe for more educational content.

What mnemonic is used to remember the stages of mitosis?

• PLAT

• PLOT

• PANT

• PMAT

During metaphase, where do the sister chromatids align?

• At the cell poles

• At the cell membrane

• Outside the cell

• In the middle of the cell

What happens to chromatids during prophase?

• They become invisible

• They split into four parts

• They condense into X-shaped chromosomes

• They disappear

What is the role of centromeres during metaphase?

• To create new DNA

• To dissolve the spindle fibers

• To attach sister chromatids

• To divide the cell

Which component is NOT part of the spindle apparatus?

• Spindle fibers

• Centrioles

• Ester fibers

• Mitochondria

What structure attaches to the centromeres during metaphase?

• Ribosomes

• Cell membrane

• Spindle fibers

• Nuclear envelope

What is the function of the spindle checkpoint?

• To create new spindle fibers

• To start cell division

• To ensure chromatids are evenly split

• To stop DNA replication

What percentage of the cell cycle does metaphase take?

• 4%

• 50%

• 25%

• 10%

What happens after metaphase in the cell cycle?

• The cell enters anaphase

• The cell enters prophase

• The cell divides

• The cell rests

What is the main purpose of metaphase in mitosis?

• To replicate DNA

• To align chromosomes for separation

• To dissolve the nuclear membrane

• To create new cells
