The basophilia of the chromatin may fade (karyolysis) because to deoxyribonuclease (DNase) activity. A second pattern is pyknosis characterized by nuclear shrinkage and increased basophilia and DNA condenses into a solid shrunken mass. In the third pattern, karyorrhexis, the pyknotic nucleus undergoes fragmentation. Within 1 to 2 days, the nucleus in a dead cell may completely disappear. نوع السؤال: خيار واحد True False

Why cell injury due to genetic causes are alarmingly increasing each year. Explain at your own words
Biologists have long been interested in the effects of radiation on cells. In one experiment, researchers examined the effect of radium on mitosis of chick embryo cells growing in culture. A population of experimental cells was examined under the microscope for the number of cells in telophase (as a measure of mitosis occurring) before, during, and after exposure to radium. The results are shown in the Figure. What is the effect of radium exposure on mitosis? Source: R. G. Canti and M. Donaldson. 1926. The effect of radium on mitosis in vitro.

When the DNA of a human cell becomes damaged, the p53 geneis activated. What is the general function of the p53 protein?Is it an enzyme, transcription factor, cell-cycle protein, orsomething else? Describe three ways in which the synthesisof the p53 protein affects cellular function. Why is it beneficialfor these three things to happen when a cell’s DNA hasbeen damaged?
Retinoblastoma is a rare cancer in which tumors developin the retina of the eye. The tumors arise because of theloss of the Rb gene, which codes for a tumor suppressor.Hereditary retinoblastoma usually appears in children whohave inherited only one functional copy of Rb. Explain whythe nonhereditary form of retinoblastoma usually occurs laterin life.
The cell cycle is typically thought of as having four stages. Describe the stages of the cell cycle and identify the mechanism(s) involved in progressing or not progressing through the stages with reference to proteins and signalling processes involved.
