Meiosis, in contrast, is the shared feature for eukaryotic sex. In fact, the problem of maintenance of sex can be largely referred to the question: “What is meiosis good for?” About 20 major hypotheses have been proposed to explain the paradox of sex, and three main theories attempt to...
What is a diploid cell? What are chromosomes made up of? If mitosis makes somatic cells, what does meiosis make? Mitosis produces which cell type? Haploid, diploid, chromosome, gamet? How many autosomes do somatic cells have? Do somatic cells contain a haploid number of chromosomes?
What do chromosomes do only once in mitosis and meiosis? Where in somatic cells does mitosis occur? How many chromosomes are in a nucleus? How many chromosomes are present at the end of in Anaphase II? When human somatic cells undergo mitosis are diploid cells made?
What causes cells to divide uncontrollably? Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. What is meiotic cell division? Meiosis is a type...
Does BAP1 require other subunits to be functional in the cytosol vs. nuclei? What are the function and tissue specificity between different compositions of these BAP1 complexes? Do all the BAP1 substrates contain similar or identical BAP1-binding motifs, and/or conserved lysine residues?
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
What is the role of the nucleus in cell division? The Nucleus: In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromosomes are identical in each cell, thanks to the process ...
Does synapsis occur in meiosis?Meiosis:Meiosis is a kind of cell division which is used to produce egg cells and sperm cells. It begins with cells which have two copies of each gene and produces cells which have a single copy of each gene....
Homologous recombination-driven crossover between parental homologs (allelic homologous recombination, or AHR) is a hallmark of meiosis32. Although AHR has been observed in somatic cells33, its contribution to cancer structural variation is unclear. AHR crossovers lead to segmental uniparental disomy (...
Does LLPS participate in the process of DSBs repair? What are the functions of LLPS in the compartmentalization of DSBs repair centers? How are these condensates induced by DNA damage? Introduction A cell can be thought of as a busy “factory”, running a variety of different tasks at the...
