Anaphase During anaphase, the centromeres divide and identical DNA molecules go to opposite sides of the cell. Telophase During telophase the spindle fibers disappear and a new nuclear membrane forms around each set of DNA molecules Gamete Formation = Egg Cells with ½ the chromosomes Meiosis Game...

Errors in chromosome segregation during meiosis will result in aneuploidy, followed by loss of the conceptus during pregnancy or birth defects. During ...

Errors in chromosome segregation during meiosis will result in aneuploidy, followed by loss of the conceptus during pregnancy or birth defects. During mitosis, cells utilize a mechani...
Cells divide and reproduce in two ways, mitosis and meiosis.Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division. What is zygotene stage? The zygotene isthe st...
How Parent Cells become Daughter Cells? Lesson Summary Frequently Asked Questions Does mitosis produce 4 daughter cells? Mitosis does not produce four daughter cells. Mitosis produces two identical daughter cells from one parent cell. In another type of cell division, called meiosis, one parent cell...
What causes cells to divide uncontrollably? Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. What is meiotic cell division? Meiosis is a type...
How many somatic cells are produced in mitosis?Cell Division:Mitosis is the process of somatic cells dividing. Cells must divide to replace old, dying cells, and for the organism to grow. Mitosis is a highly regulated process to ensure exact copying of the DNA....
If, in addition to a role in meiosis, β-Trcp1 has a general role in somatic cells, why is the in vivo phenotype not more dramatic? One possible general answer to these questions is provided by the functional redundancy of the β-Trcp1 and β-Trcp2 gene products. Interestingly, although...

Sexual cells in male fishes are microscopic and smaller than eggs in females. Due to the late maturation age in sturgeons, the biopsy of gonads and histological studies are one of the most important and reliable ways to detect and separate males and females from each other at early ages. The...
