a. chromatids do not separate at the centromere in anaphase I.
b. centromeres do not exist in anaphase I.
c. crossing-over occurs only in anaphase of miitosis

∙ 12y agoIn prophase of mitosis the sister chromatids prepare to be separated into two daughter cells. Mitosis creates two daughter cells that each contain the same number of chromosomes as the parent cell. (2n)
In prophase I of meiosis, the homologous chromosomes prepare to be separated. Meiosis I produces two daughter cells with 1/2 the number of chromosomes of the parent cell.
Prophase II of meiosis is very similar to prophase of mitosis. In prophase II, the sister chromatids prepare to separate.

What distinguishes prophase 1 of meiosis from prophase of mitosis?
In Prophase I of meiosis, a tetrad is formed between 2 homologous chromosomes and their replicates. Small pieces are exchanged between the chromosomes and the tetrad breaks up. Then things happen as usual. So really the only difference is that there's genetic recombination.
Crossing over occurs during which phase of meiosis?
Crossing over occurs during Prophase I of meiosis.
Is mitosis or meiosis involved in producing the trailing stems leaves and new roots in plants?
I think mitosis because mitosis involves growing which the plant is doing.... sorry if I'm wrong!
Is it true that DNA replication can also be called mitosis?
DNA replication is technically not part of mitosis. Mitosis is simply the splitting of the nucleus. DNA replication however is part of the interphase, which is part of the cell cycle. The DNA replication is also known as the S phase in the interphase. In this part, the DNA is replicated creating two sets of all genetic information.
During which stage of meiosis are the bivalents arranged along the equator?
During the metaphase I meiosis are the bivalents are arranged along the equator. During the prophase I of meiosis I the crossing over occurs.
What is the difference between prophase mitosis and prophase meiosis?
In prophase I of meiosis, crossing over of homologous chromosomes occurs. This does not happen in prophase of mitosis.
How are meiosis and mitosis similar?
they both have a prophase and an anaphase.
Does the nucleus disappear during mitosis and meiosis?
Yes, the nucleus dissipates during late prophase and early metaphase in mitosis, and during Prophase 1/diakinesis of meiosis.
When does crossing over happen in mitosis 1?
Mitosis does its crossing over in prophase
The most important occurrence during prophase one of meiosis which doesnt occur in prophase of mitosis is?
synapsis
Which of the following occurs in meiosis but not mitosis?
Meiosis is the division of the gametes(sex cells), haploid (n) Mitosis is cell division, diploid (2n) In meiosis, there are the similar cycles (prophase, metaphase, anaphase, and telophase), but there are two cycles of each (ex: prophase 1, prophase 2 ETC).
What are the phases in Mitosis and Meiosis?
There are Interphase, Prophase, Metaphase, Anaphase and Triphase. The two that are opposite are Interphase and Anaphase.
What stage does chromatin condense to chromosomes?
During mitosis, chromosomes are in their most condensed form during metaphase
How does metaphase 1 differ from metaphase of mitosis?
It differs because in meiosis the cell in prophase 1 just crosses over and that is really the only difference in the two.
Prophase occurs during which stage of the cell cycle?
It occurs in the first stage.
How are mitosis are meiosis similar?
They have many similar steps they both have a prophase and an anaphase
Strictly speaking mitosis and meiosis are divisions of the?
Mitosis is division of a cell. Consists of the stages Prophase, Metaphase, Anaphase, and Telaphase. Mitosis is part of the cell cycle. Meiosis is the division of a sex cell. Such as sperm or egg. Meiosis is unique because it goes through the stages twice. Prophase I, Prophase II, Metaphase I, and Metaphase II, etc.
