Cells that lose regulatory control of the cell cycle cause tumors. Specifically, loss of control of any of the three cell cycle checkpoints can lead to major issues in dividing cells. What are the three cell cy
Each chromosome in a diploid cell is part of a homologous pair. Reproductive germ cells are diploid like somatic cells until they undergo the reductionist process of meiosis to form sperm and an egg. Chromosomes replicate in the first stage of meiosis and become sister chromatids joined together ...
In what ways is meiosis II similar to and different from mitosis of a diploid cell? Binary fission differs from mitosis in that: a. it is simpler and generally associated with prokaryotic cells. b. the chromosomes contain DNA and protein rather than just DNA. c. it ...
C. Hyperplasia D. None of the choices are correct Cells of the Body: The body is comprised of multiple levels of organization. A cell is the basic unit upon which more complex organizational levels are built. Within the cell are small struc...
D) because the nondominant follicles undergo atresia. E) as a result of a fall in The main difference between oogenesis and spermatogenesis is that in oogenesis: a. the primary oocytes contain 46 chromosomes. b. the cytoplasm is eq...
Explain, generally, what hap How do CDKs regulate cell division? Also, what is the possible role of telomerase in cellular aging and in cancer formation? What are two things that happen to telomeres as cells undergo cell ...
Chitin is the main component of the pathogen cell wall. Thus, cell wall-degrading enzymes such as chitinases and β-1,3-glucanase are generally involved in the plant defense against fungal pathogens. Indeed, chitinase and β-1,3-glucanase activities were induced earlier in the resistant cultivar...
