To explain: The sister chromatids do not end up in the same daughter cell, rather they are split apart equally into two daughter cells.
Introduction: During the S phase of cell cycle, the
To explain: The consequences if a mitotic error occurs where the sister chromatids end up in the same daughter cell.
Introduction: During the S phase of cell cycle, the DNA undergoes replication and two copies of DNA are produced, which are condensed to form sister chromatid structure bound to a centromere. The cell cycle process involves the cell division, M phase. The M phase has four stages: prophase, metaphase, anaphase, and telophase. In each of these phases, the chromosomes are aligned accordingly, so that each daughter cell receives only one copy of the chromosome each. In somatic cells, where mitosis takes place, the chromosomes are present in diploid number that is two copies of the same gene as alleles are present. The alleles can be homozygous or heterozygous.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes. Which of the following Plasmodium species is most likely responsible for her severe symptoms? A. Plasmodium vivax B. Plasmodium ovale C. Plasmodium malariae D. Plasmodium falciparumarrow_forward
