What is a cleavage furrow?
A cleavage furrow is the indentation that begins to form in the cell membrane during cytokinesis, leading to cell division.
What is the role of the centromere in a chromosome?
The centromere is the region where two sister chromatids are joined together, playing a crucial role during cell division.
What are chromosomes composed of during cell division?
Chromosomes are composed of two chromatids joined at the centromere.
What is the function of the kinetochore?
The kinetochore is a protein structure on the chromosome that attaches to the mitotic spindle, facilitating chromosome movement during cell division.
What is the mitotic spindle?
The mitotic spindle is a structure made of microtubules that segregates chromosomes into daughter cells during mitosis.
What happens to the nuclear envelope during cell division?
Fragments of the nuclear envelope disassemble to allow the mitotic spindle to access the chromosomes.
