How is prophase, metaphase and anaphase of mitosis, meiosis I and meiosis II different or the same? What is the comparison and contrast between of anaphase Mitosis and anaphase 1 and 2 of Meiosis? What are the differences between metaphase I and metaphase II of meiosis? What happ...
The process in cell division by which the nucleus divides, typically consisting of four stages, prophase, metaphase, anaphase, and telophase, and normally resulting in two new nuclei, each of which contains a complete copy of the parental chromosomes.Also called karyokinesis. Meiosis Rhetorical unde...
The formation of bivalents will ensure that the genetic composition is mixed between the gamete cells. Upon the formation of bivalents, a tension is created and eachchromatidis pulled in the opposite direction. This will allow the bivalents to arrange in the center of the cell. What are Chia...
Usually, it refers to individuals who have the potential to produce something original. This allows the writer to make use of the natural talent that he has for writing and create an original piece. Even in schools there are competitions for creative writing. Once again, the objective of such...
Without the kinetochore, chromosomes wouldn't align at the metaphase plate. 4 Centromere The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids (a dyad). During mitosis, spindle fibers attach to the centromere via the kinetochore. Kinetochore A kinet...
Whereas prophase I starts with duplicated genetic material, prophase II starts with the results of telophase I—23 chromosomes with two chromatids each. These chromosomes line up at the center of the cell in metaphase II and the chromatids are pulled apart from one another at the centromere in...
How do chromosomes behave in prophase 1 and metaphase 1 and how does this allow variation to take place? What is the difference between DNA and RNA? Describe the activity of chromosomes in each stage of meiosis 1 and meio...
Figure 2: Plant Cell Division Mitosis occurs through four steps as described below: Prophase– Condensation of the chromosomes and the formation of the mitotic spindle; Metaphase– Aligning of the chromosomes in the equatorial plate; Anaphase– Constriction of the microtubules of the mitotic spindle ...
Interphase has three sub phases; G1 phase, S phase and G2 phase.Prophase has no sub phases. Cell Growth Cell growth occurs in interphase.Cell growth stops in prophase. Followed By Interphase is followed by prophase.Prophase is followed by metaphase. ...
The key difference between cell plate and metaphase plate is that the cell plate is a physical interphase present only in plants and in some algal cells, w
