WebWhich of the following occur during prophase? a) mitotic spindle begins to form b) nuclear envelope form c) sister chromatids separate d) chromosomes line up on the midline of the cell a) mitotic spindle begins to form ________ describes a site of crossing over. a) centromere b) synapse c) chiasma d) histone c) chiasma Web13 mei 2024 · The first and longest phase of mitosis is prophase. During prophase, chromatin condenses into chromosomes, and the nuclear envelope (the membrane surrounding the nucleus) breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles of the cell.

In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.
WebThe mitotic spindle begins to form. The spindle is a structure made of microtubules, strong fibers that are part of the cell’s “skeleton.” Its job is to organize the chromosomes and move them around during mitosis.

Webactin network is responsible for spindle migration towards the oocyte cortex8–10 and, if the microtubule spindle is disassembled, chromosomes are still repositioned towards the cortex via direct interactions with actin cables10.
