Which important phenomenon is both inspected during g1 and g2 checkpoints of the cell cycle?DNA damagelevel of proteinscell sizegrowth factors

There are three checkpoints in the cell cycle responsible for detecting errors during cell replication. These are the G1 checkpoint, the G2 checkpoint, and the metaphase checkpoint.Describe the changes to a cell during metaphase.

At which of the following checkpoints will the cell cycle stop if DNA damage is detected?  Spindle checkpoint during S phase   G2 checkpoint between S and G2 phases The G2 checkpoint does check for DNA damage (due to faulty DNA replication), but it is located between G2 phase of interphase and the beginning of M (mitotic) phase. Try again.  G1 checkpoint between G1 and S phases   Mitosis checkpoint during M phase

The Cell Cycle Control System is based on a connected series of biochemical switches that initiate specific events. What checkpoints are during the Cell Cycle? Initiation of transcription, translation, post-translation modification DNA replication and mRNA splicing, Start in late G1, G2/M transition, Metaphase-to Anaphase transition Translation and ribosome assembly Interphase to interphase checkpoint, Start G1, Telophase-to-prometaphase transition

16. Which of the following characteristics would you use to evaluate if a cell cannot pass through the Gap 1 checkpoint?*1 pointA. A cell with a large enough size to divideB. A cell with little DNA damageC. A cell with almost enough growth factors and nutrientsD. A cell that is small enough to divide faster17. The diploid number of chromosomes for the house fly is 12. What would be the number of chromosomes after mitotic division?*1 pointA. 3B. 6.C. 12D. 2418. Suppose there is a cell with a diploid number of chromosomes of 26. After one round of meiosis, what will be the ploidy and chromosomal number of the daughter cells?*1 pointA. 13, 2nB. 13, nC. 26, nD. 26, 2n19. Which of the following statements can best explain genetically non-identical sister chromatids present at metaphase II?*1 pointA. They each represent different chromosomes.B. There is an error in the pairing of homologous chromosomes during meiosis I.C. One is maternal, and the other is paternal in origin.D. The crossing over during meiosis I20. How would you describe the relationship between crossing over and recombination?*1 pointA. Recombination is the process of homologous chromosomes swapping segments of DNA, resulting in crossing over.B. Crossing over allows the swapping of DNA segments from one homologous chromosome to another, resulting in the recombination of genes and genetic variation.C. Genetic recombination occurs when the chiasma breaks and broken chromosome segments get switched onto the other homologous chromosome, producing different combinations of alleles in the offspring.D. There is no relationship between the two.21. Ilene inherited a genetic mutation from her mother. During which stage of cell division did the mutation likely occur?*1 pointA. Prophase of mitosisB. Prophase 1 of meiosis 1C. Telophase of mitosisD. Cytokinesis of meiosis 122. Which of the following results best describes the advantage brought about by crossing during cell division?*1 pointA. It results in the development of distinct features in children from either parent.B. It provides an exhaustible store of gene variability in asexually reproducing organisms.C. It allows the exchange of genetic material between sister chromatids of homologous chromosomes.D. It produces little variation of alleles in the offspring.23. Scientists are developing techniques for therapeutic cloning to replace damaged tissues. Which of the following processes is the most important for multiplying the desired healthy cells?1 pointA. Meiosis creates genetically diverse cells, increasing the chance for having the desired healthy cells.B. Mitosis ensures the daughter cells inherit identical genetic makeup of the healthy cell for their controlled expansion during cloning.C. Meiosis combines genetic materials to select the desired healthy traits of the cells to be used for cloning.D. Mitosis preserves the desired healthy characteristics and add variation to guarantee genetic fidelity.24. A population of rabbits experienced a sudden change in their environment, with colder temperatures becoming the norm. Over several generations, some rabbits developed thicker fur, providing an advantage in the colder climate. Which of the following statements would you select to support the idea that meiosis is the most critical process for the emergence of this adaptation?*1 pointA. Meiosis produces gametes used by of rabbits with thick fur, which are more likely to survive, to reproduce in the colder environment.B. Meiosis enables the heritability of thicker fur so that it can be passed from parents to offspring.C. Meiosis shuffles the genetic material during gamete formation in rabbits.D. None of the above.25. Which of the following genetic disorders is caused by an abnormal number of chromosomes and is characterized by intellectual disabilities and distinct physical features?*1 pointA. Diabetes mellitusB. Down syndromeC. Cystic fibrosisD. Alzheimer's disease
