Haplontic life cycle refers to the fact that it involves one generation of entities whose cells are haploid. Haplontic life cycle is a trait of... View Article
In this stage, the chromosomes directed by its centromeres move to the equatorial planes in the middle of the cell, right angles to the axis... View Article
Prophase accounts for over half of the mitotic division. The duplicated centrosomes start moving to the opposite ends of cells. The centrosomes... View Article
This phase was believed to indicate the resting phase between consequent cell divisions. However, new studies indicate that it is a highly active... View Article
In mitosis, exact replicas are produced and this is observed in almost all the cells of the body. Meiosis on the other hand is a type of cell... View Article
The two meiotic divisions are referred to as the first and the second meiotic divisions. During meiosis I, the chromosomal number is reduced,... View Article
It is during Anaphase I that the Segregation of Mendelian factor occurs. During meiosis I, the paired homologous chromosomes drift for each... View Article
The daughter cells in meiosis differ from the parent cell and also amongst themselves as a result of crossing over, segregation and independent... View Article
Mitotic anaphase varies from the metaphase in having the equivalent number of chromosomes and half the count of chromatids. The chromosomes split... View Article
Meiosis II is shorter than a regular mitotic division due to the reduction of the prophase of such a division. This division preserves the... View Article
Meiosis involves the interchange of genes between homologous chromosomes. Thus, the gametes produced are different from each other genetically.... View Article
Crossing over is accountable to induce variability. It entails an interchange of equal portions of non-sister chromatids which belong to 2... View Article
Spindles are microtubular apparatus appearing in several eukaryotic cells at the commencement of the division of the nucleus. It is regarded for... View Article
Mitosis occurs both in germ cells and somatic cells of the gonads. Mitosis in plants occurs in the meristematic cells of shoot tip or root tip.... View Article
In anaphase I, two chromatids of a chromosome from each tetrad progress as a unit to a pole of a spindle. The other two chromatids of its... View Article
The recombinase enzyme participates in the pachytene stage of prophase I. This phase is defined by the occurrence of recombination nodules, the... View Article
The complex as a result of a pair of synapsed homologous chromosomes is bivalent. Chromosomes start to pair in the zygotene stage and are known... View Article
Pachytene is the 3rd phase of meiosis prophase-1 (a five-stage process). It is characterized by the appearance of recombination nodules, the... View Article
The process of association of homologous chromosomes is synapsis. It occurs during the zygotene phase of prophase I of meiosis. This particular... View Article
