Understanding Prophase in Mitosis

This video from Mumu Math and Science explains prophase, the first step of mitosis. It covers how DNA condenses into chromosomes, the appearance of spindle fibers, and the breakdown of the nuclear membrane. An animated video illustrates these processes. The video concludes with a summary and encourages viewers to subscribe for daily content.

What is the first stage of mitosis?

• Metaphase

• Anaphase

• Prophase

• Telophase

During prophase, what does the duplicated DNA condense into?

• Nuclei

• Chromosomes

• Ribosomes

• Centrioles

Which of the following can be observed with a regular compound microscope during prophase?

• Endoplasmic Reticulum

• Mitochondria

• Chromosomes

• Golgi Apparatus

What is the role of spindle fibers during prophase?

• They condense DNA

• They attach to chromosomes

• They dissolve the nuclear membrane

• They replicate DNA

What happens to the nuclear membrane during prophase?

• It thickens

• It disappears

• It doubles

• It remains unchanged

Which structure do spindle fibers attach to on the chromosomes?

• Telomeres

• Nucleosomes

• Chromatids

• Centromeres

What is the final event that occurs during prophase?

• DNA replicates

• Chromosomes align

• Nuclear membrane breaks down

• Cell divides
