Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus ...
Cell division is a vital process for the continuous replacement of old and damaged cells, growth of the body, and to perform vital cellular functions. The cell division occurs in two forms, namely mitosis, which occurs in somatic cells to increase the mass and size of an individual, while ...
Mitosis happens when you want to grow, for example. You want all your new cells to have the same DNA as the previous cells. The goal ofmeiosis, however, is to produce sperm or eggs, also known as gametes. Are gametes formed through mitosis? Gametes areproduced by mitosis(not meiosis) a...
Does nondisjunction occur in mitosis?Mitosis:Mitosis is a biological process of cell division found in organisms with cells containing a nucleus. Essentially, mitosis divides a single cell into two identical daughter cells, each with the same number of chromosomes as the original parent cell....
(c) They can exchange genetic material with other ciliates by the process of mitosis. (d) Most live as s What are the thin strands located in the cytoplasm of a human cheek cell? What is the name of the process where the cytoplas...
Cyst progenitor (stem) cells are divided to form cyst cells, two of which surround a primary gonial cell. The primary gonial cell undergoes several rounds of mitosis, aborted meiosis I and normal meiosis II. The haploid spermatids then elongate with the growth of the sperm tails. The germ ...
We studied the biologic effects of MplK on TPO-mediated cell growth by determining the capacity of the receptor to produce a proliferative signal in interleukin-3–dependent BaF3 cells or to modify TPO-mediated growth of BaF3 cells bearing the MplP receptor. As expected, MplK did not transduce ...
To examine effects on cells that were not undergoing mitosis, we examined ornithine decarboxylase (ODC), an enzymatic marker for cell damage. One day old rats showed inhibition of ODC by hypoxia, a response that represents preservation of cell integrity; by 8 days of age, ODC was increased ...
Does mitosis produce somatic cells or gametes? What is the pairing of homologous chromosomes during meiosis? What happens during metaphase I of meiosis? What happens in metaphase of meiosis 1? Which process must occur before mitosis and meiosis can occur? During which of these stages of meiosis ...
Describe how glyceraldehyde-3-phosphate is changed to produce pyruvate. How do the nucleus, mitochondria, cytoplasm, ribosomes, and Golgi apparatus all interact together? What happens to cell organelles during mitosis? Does protein degradation happen in mitochondria? How has cell theory changed over ...
