Which of the following best describes the way in which all initiator procaspases are directly activated? Cytochromec release. Being brought into proximity with each other. Via FAS ligand activity. By BCL2 family proteins. By Apaf1. Which of the following statements about meiosis and mitosis is false? Non-disjunction of chromosomes during meiosis II produces haploid cells containing non-sister chromatids. Homologous (i.e. paternal and maternal) chromosomes never pair during mitosis. Meiosis involves a round of cell division without prior DNA synthesis. Extremely low rates of recombination occur between sister chromatids during mitosis. A subset of cohesins is protected from separase activity during meiosis I.Explanation / Answer
Please find the answers below:
Answer 5: Choice 3 (the Fas ligand activation is involved directly not only in activation of death signal by mitochondria dependent caspasce 3 and 7 but also involved directly in activation of mitochondria independent caspases such as 2, 8 adn 10. The actiavation of Fas mediated death signals under stress/stimuli coherently induce activation of these signals and thus lead to apoptosis)
Answer 6: Choice 5 (although separase acts upon almost all the cohesin proteins on the chromosomes, but the evolutionarily protected and structurally intact regions of the chromosomes such as centromere are protected from separase activity. If a chromosome's centromere is affected by separase activity, it will split up into single strands and the chromosomal structure will be distorted.)
