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
In 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.
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 Prophase I of meiosis.
I think mitosis because mitosis involves growing which the plant is doing.... sorry if I'm wrong!
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 the metaphase I meiosis are the bivalents are arranged along the equator. During the prophase I of meiosis I the crossing over occurs.
In prophase I of meiosis, crossing over of homologous chromosomes occurs. This does not happen in prophase of mitosis.
No, prometaphase is a stage in mitosis, not meiosis. In meiosis, there is a prophase I stage that is similar to prometaphase in mitosis.
they both have a prophase and an anaphase.
Mitosis does its crossing over in prophase
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).
There are Interphase, Prophase, Metaphase, Anaphase and Triphase. The two that are opposite are Interphase and Anaphase.
During mitosis, chromosomes are in their most condensed form during metaphase
It differs because in meiosis the cell in prophase 1 just crosses over and that is really the only difference in the two.
They have many similar steps they both have a prophase and an anaphase
Mitosis for sure has metaphase. Scientists are guessing that meiosis has it too, but they combine it and make it "prometaphase," because prophase and metaphase happens so fast in meiosis.
Both meiosis and mitosis are forms of cell reproduction.They both have a prophase and an anaphase.Both are forms of cell reproduction/Both are forms of nuclear division. Meiosis occurs in generative cells and mitosis in somatic cells.
The chromosomes condense in prophase of mitosis. https://en.wikipedia.org/wiki/Mitosis#/media/File:Animal_cell_cycle-en.svg
