Mitosis for Anatomy and Physiology

The video tutorial covers the process of mitosis, detailing each phase: prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis. It explains the transformation of chromatin into chromatids, the role of spindle fibers, and the separation of sister chromatids. The video also describes the reformation of the nuclear membrane and the division of the cell into two new cells.

What is the primary structure that chromatin condenses into during the initial stages of mitosis?

• Kinetochore

• Centromere

• Chromosome

• Chromatid

During prophase, what structure do sister chromatids join at?

• Centromere

• Spindle Fiber

• Kinetochore

• Nucleolus

What is the role of centrosomes during prophase?

• To dissolve the nucleus

• To synthesize spindle fibers

• To form the nucleolus

• To replicate DNA

In prometaphase, what happens to the nuclear membrane?

• It thickens

• It breaks down

• It duplicates

• It becomes more rigid

What is the function of spindle fibers during prometaphase?

• To form the nucleolus

• To replicate DNA

• To attach to kinetochores

• To dissolve chromatin

During metaphase, where are the chromosomes aligned?

• In the nucleolus

• In the cytoplasm

• At the metaphase plate

• At the cell poles

What process occurs during anaphase?

• Nuclear membrane forms

• Sister chromatids separate

• Spindle fibers dissolve

• Chromosomes condense

What significant event occurs during telophase?

• DNA replicates

• Spindle fibers form

• Nuclear membrane reforms

• Chromosomes condense

What is the role of the contractile ring during cytokinesis?

• To dissolve the nucleus

• To form spindle fibers

• To replicate DNA

• To split the cell

What is the cleavage furrow associated with?

• Chromosome alignment

• DNA replication

• Cell division

• Nuclear formation
