There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3)Anap...
It has previously been suggested that cancerous transformation may result in a shorter cell cycle =-=(34)-=- and, therefore, in a larger number of cell divisions. However, it is important to note that growth of a tumor cell population does not necessitate shortening of the cell cycle, ...
Given below is a diagram representing a stage during mitotic cell division. Study it carefully and answer the questions that follow: How will you differentiate between mitosis and meiosis on the basis of the chromosome number in the daughter cells?

Compare the end products (resulting cells) of mitosis and meiosis. This will include number of cells produced, diploid/haploid, genetic variation etc. Cell Division: We encounter two types of cell division in the field of biolog...
Mitosis is the process by which one cell undergoes cell division to create two new identical daughter cells. The phases of mitosis include: prophase, metaphase, anaphase, and telophase. These phases are followed by cytokinesis, which...
Structural rearrangements of the genome resulting in genic imbalance due to copy number change are often deleterious at the organismal level, but are common in immortalized cell lines and tumors, where they may be an advantage to cells. In order to explo
significance for karyotype evolution and speciation Vladimir A Lukhtanov1,2*†, Vlad Dincă3,4†, Gerard Talavera3,4 and Roger Vila3,5* Abstract Background: Species generally have a fixed number of chromosomes in the cell nuclei while between-species differences are common and often ...
In anthers, each of the four archesporial initials undergoes a series of periclinal divisions to form the primary sporogenous cells and the radial anther wall cell layers — the endothecium, middle cell, and nutritive tapetum. These cell types form the microsporangium in which the sporogenous ...
The present invention relates to the use of the ANG4 gene, or a variant thereof, to modulate the cell number of a plant organ. Said modulation can be used to increase the plant biom
