Mitosis affects life bydirecting the growth and repair of trillions of cells in the human body. Without mitosis, cell tissue would rapidly deteriorate and stop working properly. Which phase does mitosis and cytokinesis occur? M phase. During the mitotic (M) phase, the cell divides its copied ...
Monosomy occurs when the zygote receives only one copy of a chromosome andoverall occur far less frequently than trisomy because an entire missing autosome (nonsex chromosome) isnearly always lethal.

Why does DNA replication occur prior to mitosis? Why is DNA replicated prior to mitosis? Why are bacteria classified as prokaryotes? Why does transcription occur in the nucleus and not in the cytoplasm in eukaryotes? Why is protein synthesis different in prokaryotes and eukaryotes?
How does a DNA virus cause cancer? Why does DNA synthesis proceeds in the five-to-three direction? Why, in the laaging strand, DNA polymorase can not replicate the DNA continuously? Does cordycepin inhibit DNA synthesis? Why does DNA replication occur prior to mitosis?
Depending on population structure, the ratio of male to female gametes may be male-biased in Plasmodium, but because gametogenesis involves only three more rounds of mitosis for each male compared with each female, the opportunity for mu- tational bias to result in fast-male evolution...
Endocytosis refers to invagination of a small region of plasma membrane, forming an interacellular membrane-bound vesicle. It has been observed in many kinds of animal cells, where the plasma membrane is in direct contact with external medium. Endocytosi
If it wasn't for this layer of skin and its ability to remain in continuous mitosis, we would still have scrapes from kindergarten! Answer and Explanation: The skin cells that undergo mitosis continuously are the epidermis cells. Looking at a bisection of your skin, it is made of many laye...
The nucleus contains DNA separated into a number of chromosomes, with the total number varying between species (humans have 46). During the process of mitosis, the nuclear membrane dissolved, chromosomes that have already been duplicated in pairs are pulled apart, and the nucleus and cell divide...
Their generative cell contains a few plastids which, however, are selectively degraded (by an unknown mechanism) prior to division of the generative cell into the two sperm cells in pollen mitosis II. Both mechanisms must be under genetic control of the paternal gamete. Species of...
