Question
The following statement is true about a tumor suppressor gene mutation to induce cell division of a mammalian cell: Proto-oncogene product must have decreased activity. tumor suppressor gene product must lose activity. Tumor suppressor gene product must have an increased activity. Proto-oncogene must lost ability to express mRNA. Incidence of cancer in human increases with age suggesting that: Cancer is an infectious disease? Multiple mutations are required to develop cancer. Cancer gene(s) cannot be acquired in lifetime. None of the above are Which of the following is true concerning cancer cells? They do not exhibit density-dependent Inhibition when growing in culture When they stop dividing, they do so at random points in the cell cycle. They are not subject to cell cycle controls. B and C only A, B, and C Posttranslational modification of a protein includes: Folding of a protein by chaperones Cleaving off some amino acids. Phosphorylation of protein All of the above. Why do histones bind tightly to DNA? Histones are positively charged, and DNA is negatively charged. Histones are negatively charged, and DNA is positively charged. Both histones and DNA are strongly hydrophobic. Histones are covalently linked to the DNA. Histones are highly hydrophobic, and DNA is hydrophilic.
