The first gap in the cell cycle (G1) corresponds to: A.the beginning of mitosis B.the phase in which DNA is being replicated C.the phase between DNA replication and the M phase D.normal growth and functioning When does DNA synthesis occur in mitosis? What happens to telomeres during DNA...
If the process of mitosis goes wrong, it usually happens in a middle phase of mitosis called metaphase, in which the chromosomes move to the center of the cell and align in an area called the metaphase plate. If they do not align correctly, they cannot move individually to opposite poles ...
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...
S (synthetic phase), G2(second gap phase) and mitosis. In G1, the cell makes duplicates of every component of the cell with the exception of the chromosomes. In S, which takes about 10 to 12 hours and consumes roughly half of the life cycle in mammals, all of...
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 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 in metaphase II?Meiosis:Meiosis is a method of cell division that is used to produce haploid gametes. Meiosis is actually two consecutive cell divisions. During the first cell division, homologous chromosomes are separated from each other, and two daughter cells are made. Each of ...
Telophase =Tear Prepare - middle - apart - tear.The idea with this one is to use one word that sort of sums up what happens in each phase of mitosis to trigger your memory about the other details of what happens in that phase. So, for example, if you can remember prophase = prepare...
the four-stage process of mitosis. Duringcytokinesis, the nuclear envelope, or nuclear membrane, that encloses the nucleus's genetic material remains unchanged, as it was dissolved and reformed into two separate membranes in an earlier mitosis phase. The nuclear membrane reforms during telophase. ...
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...
