英语翻译原文:Process of MeiosisUnlike the single-cell division of mitosis,meiosis involves two cellular divisions:meiosis I and meiosis II.Each stage of meiosis runs through the same five stages as discussed in mitosis.During the first round
The meiotic process, considered an alternative of the mitotic process when it occurs in somatic cultured plant cells, is discussed in detail, taking into account the importance, for evolutionary purposes, of this source of genetic variation. A new concept of cell totipotency is formulated, as ...
During early embryonic development, first emerged germline cells are called primordial germ cells (PGCs).12The PGCs are the founder cells of the germline, to some extent, also the source of germline totipotency, ensuring the creation of new organisms.13In humans, when, where, and how first PG...

schoeno- prasum is more abundant, and typically occurs in densely vegetated valley mires and water meadows. Flowering is prolific in these localities. It appears, therefore, that British populations of A. schoeno- prasum are somewhat more ecologically marginal than their continental counterparts. ...
Fertilization and Implantation are essential phases in the reproduction process. The process of fertilization in humans includes different stages followed with the implantation and Sex determination.
Also, it might be that non-disjunction, resulting in both losses and gains, occurs in a higher rate but the cells with complementary chromosomal content are eliminated or are not analyzable. More recently, a combination of FISH, CGH and aCGH shows no excess of chromosome losses compared to ...
In mammalian cells, SUMO-1 is identified on mitotic spindles and in spindle midzone whereas, SUMO-2/3 localize in the centromeric region, suggesting that SUMO regulation influences more than one stage of mitosis [Citation56]. In both budding yeast and humans, many sumoylated mitotic proteins ...
Humans might be susceptible to environmental disruptions of chromatin organization The extent to which humans are exposed to TBT and how this may contribute to obesity remains unclear due to a paucity of longitudinal epidemiological studies. Because of their phylogenetic proximity, it is possible that ...
Condensation of hundreds of mega-base-pair-long human chromosomes in a small nuclear volume is a spectacular biological phenomenon. This process is driven by the formation of chromosome loops. The ATP consuming motor, condensin, interacts with chromatin
