AP BIOLOGY

Detailed explanation-1: -Common mistakes and misconceptions. Interphase is not part of meiosis. Although a cell needs to undergo interphase before entering meiosis, interphase is technically not part of meiosis. Crossing over occurs only during prophase I.

Detailed explanation-2: -Chromosomes exist at all different phases of the cell cycle. They condense and become visible to light microscopy in prophase of mitosis or meiosis, and they decondense during interphase, in the form of chromatin (DNA wrapped around nucleosomes, like “beads on a string”).

Detailed explanation-3: -Answer and Explanation: Interphase doesn’t occur a second time because after the first division of meiosis the cell only contains half the chromosomes necessary to perform its functions.

Detailed explanation-4: -Answer and Explanation: Interphase occurs before meiosis. Interphase is the part of the cell cycle where the cell is growing and does its job. Interphase is composed of three phases prior to meiosis.
