Best answer: Which of the following events does not occur during prophase 1 of meiosis?

Which of the following events occurs during prophase 1 of meiosis?

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

Which of the following events does not occur in meiosis 1?

Option C is the answer. Crossing over of nonsister chromatids of the homologous chromosomes happens during pachytene stage of meiosis I.In the option it is given crossing over of sister chromatids which is wrong.

Which of the following events does not occur during prophase?

Which of the following events does not occur during prophase of mitosis? The mitotic spindle breaks down.

What occurs in prophase 1 that does not occur in mitosis?

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.

Which of the following events happen during phase 1?

G1 or growth 1 phase, is the first phase of the cell cycle that takes place in eukaryotic cell division. In the G1 phase, the cell synthesizes mRNA and proteins that are required for DNA synthesis and prepares itself for subsequent steps that lead to mitosis. It is the longest phase of the cell cycle.

Which of these events occurs during prophase?

During prophase, the chromosomes condense and centrosomes move to opposite sides of the nucleus, initiating formation of the mitotic spindle. Breakdown of the nuclear envelope then allows spindle microtubules to attach (more…)

Which of the following events don’t occur in meiosis?

In meiosis , synapsis ( Pairing of homologous chromosome ) , Crossing over ( exchange of chromosomal segment between nos sister chromatids ) occurs which does not occur in mitosis.

What events does not take place during meiosis?

The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.

What happens in meiosis I?

In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.

Which is not associated with prophase?

What is not true about interphase? The nucleus completes its reproduction. Which is NOT associated with prophase? The nucleus reforms.

What events occur during prophase quizlet?
