What happens to the DNA (chromosomes), nuclear envelope, nucleolus, centrosomes, and spindles in the cell during the following stages of mitosis? A. Prophase B. Metaphase C. Anaphase D. Telophase Which subphase of interphase is correctly described? a. G2: Step right before prophase. b. S:...
drawing the chromosomes closer to centrioles at the poles of the cell. The chromosomes move towards the centrioles in a way that one chromosome from each pair moves towards each pole. Duringtelophase, the chromosomes
List the stages of meiosis and mitosis and describe what happens during each. What is the first phase of Mitosis? What occurs immediately before a cell enters the telophase stage? a. prophase b. G1 c. anaphase d. M e. metaphase
What happens during Pachytene? During the pachytene phase,the chromosomes become shorter and thicker and split into two chromatids joined by the centromere. Pachytene is a lengthy phase, lasting about 12 days in the rat; during this time there is a marked increase in cellular and nuclear volu...
What happens to the nuclear envelope towards the end of diakinesis in prophase I? Q. Regarding the assertion and reason; choose the correct option___. Assertion [A]: Prophase I of Meiosis I is the longest phase during the formation of gametes. Reason [R]: It has five sub stages Lepto...
What happens during prophase I of meiosis? What happens during synapsis in prophase 1? What happens in prophase II? What happens to the gametes if nondisjunction occurs at anaphase 2? What happens before mitosis? What happens in meiosis during telophase II? What happens to chromosomes during meio...
(this part is omitted from many sources), anaphase and telophase. Mitosis is in turn one part of the overall cell life cycle, most of which is spent in interphase. Metaphase might best be conceived of as a step in which the elements of the soon-to-divide cell arrange themselves into a...
Mitosis is a process that happens in phases thatalwaysoccur in the same order and accomplish the same tasks (unlesssomething goes wrong!).The four phases of mitosis are prophase (P), metaphase (M), anaphase (A), and telophase (T).Each of these phases helps achieve the purpose of mitosis...
What happens in meiosis ll? During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes. ... Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis. What is crossing over in mei...
and this is when the official division of one cell into two happens. First, the chromosomes relax back into chromatin and a nuclear envelope forms around each chromatin blob, making it into a brand new nucleus. A nucleolus appears in each of these new nuclei during telophase as well, and ...
