A) interphase
B) prophase

Nuclear Envelope

Double membrane that surrounds the nucleus in eukaryotic cells and is connected to the endoplasmic reticulum; has pores that allow substances to pass between the nucleus and the cytoplasm.

Mitosis

A process of cell division that results in two genetically identical daughter cells developed from a single cell, ensuring that each daughter cell receives an exact copy of the parent cell's DNA.

Chromosomes

Structures within the cell nucleus made of DNA and protein, containing genes that are the blueprint for an organism's traits and functions.
