Which of the following events is associated with prophase?

Which of the following happens during prophase stage?

During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized.

What events occur during prophase quizlet?

Which events occur during prophase? The nuclear envelope breaks down. Chromosomes condense and are attached to spindle fibers. You just studied 30 terms!

Which of the following events occur during prophase of mitosis?

The correct answer is (c) synapsis and crossing over. During prophase I of meiosis, synapsis and crossing over take place.

What happens in prophase of meiosis?

During prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. … A large structure called the meiotic spindle also forms from long proteins called microtubules on each side, or pole, of the cell. Between prophase I and metaphase I, the pairs of homologous chromosome form tetrads.

Which of the following happens to chromosomes during prophase?

During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase. … Cohesin forms rings that hold the sister chromatids together, whereas condensin forms rings that coil the chromosomes into highly compact forms.

What does not happen during prophase?

Crossing over is the only answer choice that does not occur during mitosis. Crossing over occurs during prophase I of meiosis and involves swapping of genetic information between homologous chromosomes. This require the formation of tetrads, which does not occur during mitosis.

What occurs during prophase of mitosis quizlet?

What happens during prophase? A cells genetic DNA condenses, spindle fibers begin to form and the nuclear envelope dissolves. … The duplicated chromosomes line up and spindle fibers connect to the centromeres. You just studied 9 terms!

  • prophase. chromatin condenses to form visible chromosomes. Nuclear envelope disappears. …
  • Metaphase. Chromosomes align on the metaphase plate.
  • Anaphase. chromosomes split and daughter chromosomes migrate to poles; cytokinesis often begins.
  • telophase. Chromosomes reach poles; nuclear envelope re-forms.

What are two events of prophase quizlet?

Chromosomes condense, the spindle forms, and the nuclear envelope disintegrates.
