Mitosis and meiosis are important processes. \\ a) What does each accomplish; \\ b) where in the human body can each occur and \\ c) how do the cells produced compare in chromosome number to the parent cells? If a cell has 20 centromeres, how many chromosomes does it have?
Do gametes or somatic cells have 23 chromosomes? What is the chromosome number found in humans cells after meiosis I is completed? What are replicated chromosomes? What is a set of chromosomes? Which cell would contain a single copy of each of the human body's 23 chromosomes?
Female mammalian cells have two X chromosomes but only one is active after embryonic development owing to random X inactivation1,2,3,4. Thereafter, each XX cell expresses either the maternal X (Xm) chromosome or the paternal X (Xp) chromosome, causing a cellular mosaicism in parent-of-X ori...
There is a need to define regions of gene activation or repression that control human kidney cells in states of health, injury, and repair to understand the molecular pathogenesis of kidney disease and design therapeutic strategies. Comprehensive integration of gene expression with epigenetic features ...
pericentromeric regions and the Y. By generating flies with different sex chromosome karyotypes (XXY females and X0 and XYY males), we show that repeat de-repression and average lifespan is correlated with the number of Y chromosomes. This suggests that sex-specific chromatin differences may ...
the chromosomes are thread-like strands of DNA and protein that are contained in the nucleus. They occur in pairs in all of the cells of eukaryotes except the reproductive cells. In bacterial cells, which have no nucleus, the chromosome is a circular strand of DNA located in the cytoplasm....
(i) List the chromosomal disorders a human may suffer from if karyotype analysis of the individual shows 47 chromosomes instead of normal 46 (ii) Explain the cause that results in the gain of chromosome number. (iii) Mention the symptoms of any one the disorders an individual can suffer ...
The diploid (2n) number of chromosomes for a human being is? The number of chromosomes in human gametes is: a. 23 pairs b. 46 c. haploid d. diploid If there are 12 chromosomes in an animal cell in the G1 stage of the cell cycle, what is the diploid number of chromosomes for...
How many pairs of chromosomes are in the nucleus of a human cell? Is this number always the same? Chromosomes: The chromosome is simply the DNA molecule that carries the genetic make up (genome) of a cell. Chromosome plays an important role during meiosis ...
