Why is it important in cell division for chromosomes to be transmitted unchanged to daughter cells? Daughter cells of mitosis have the same number of chromosomes as the parent cell while daughter cells of meiosis have half the number of chromosomes as the parent cell. What i...
Do different somatic cells have the same DNA? Can somatic cells have a different number of chromosomes? Do somatic cells end with the same amount of chromosomes? Is an autosomal cell the same as a somatic cell? Are gametes cells genetically identical to somatic cells? Do all human cells ...
In particular, we have focused on a progenitor cell that is likely to produce a mixed lineage, generating both a pericardial heart cell and a somatic muscle founder cell. We show that the asymmetric segregation of Numb into one of these daughter cells antagonizes the function of Notch and sp...
Each of those parents must have a mutation on an autosomal chromosome, the chromosomes that aren't related to gender. Research indicates that a mutation on the TRKA (NTRK1) gene, which appears to control nerve growth, may be the culprit. There are no reliable statistics on how many people...
While at a stay in the hospital delivering my daughter, the nurse failed to realize that she had not tended to my catheter, which I had due to being induced and receiving an epidural. In short, I left the hospital with a UTI and had recurring UTIs for years since then, even having ...
Questions 9 to 11 are based on the passage you have just heard. 9. A) The rate of their growth increased dramatically. B) The growth of their new brain cells doubled. C) They began to show signs of depression. D) They began to get irritated and restless. 10. A) To avoid...
Genetic transmission within such specions is fully clonal (in all mitoklonons and some meioklonons), each daughter having the same genome as her mother (except for recent mutations), or meroclonal (Dubois, 2008a, Dubois, 2009a), i.e., partially clonal, at least for some generations (in...
Chen et al36 have provided evidence that this occurs through mitotic non- dysjunction, ie, failure of a chromosome 4 pair bearing the wild-type KIT allele to separate during mitosis, leaving one daughter cell with a single chromosome 4 containing the mutant KIT allele (uniparental monosomy). ...
