Cancer is generally caused due to the activation/conversion of and or inactivation of (a) Oncogene, tumour suppressor gene, proto-oncogene (b) Tumour suppressor gene, oncogene, proto-oncogene (c) Proto-oncogene, oncogene, tumour suppressor gene (d) Oncogene, proto-oncogene, tumour suppressor gene
Which of the following series of events is associated with the formation of cancer? a)The proto-oncogenes mutate and become oncogenes which are continuously active. There is also an associated loss of tumor suppressor gene activity allowing uncontrolled growth of cells. b)The oncogenes mutate and become proto-oncogenes which are continuously active. There is also an associated loss of tumor suppressor gene activity allowing uncontrolled growth of cells. c)The proto-oncogenes mutate and become oncogenes which stop functioning altogether. There is also an associated increase in the tumor suppressor gene activity allowing uncontrolled growth of cells. d)The oncogenes mutate and become proto-oncogenes which stop functioning altogether. There is also an associated increase in the tumor suppressor gene activity allowing uncontrolled growth of cells. Place the correct word into each sentence for more information on the different types of mutations. words: start, three, one, similar, stop, different Point mutations include changes in ____________ base of a segment of DNA. A point mutation can result in no change or a ____________ protein being made. Sometimes a point mutation can lead to an improper ____________ codon resulting in the production begin stopped before the protein is completely made. Place the correct word into each sentence to describe the different types and causes of mutations. words: mutation, ingestion, can, cannot, protein, inherited, sex, gonad, exposured, body, spontaneous A gene ____________ is a change in the sequence of bases of DNA. These changes in bases can affect ____________ production, protein activity, or have no effect on protein production at all. Germline mutations are those that occur in ____________ cells and ____________ be passed onto future generations. Somatic mutations occur in ____________ cells of an individual. Some mutations are ____________ and happen for no apparent reason. Other mutations are called induced mutations and are the result of ____________ to toxins or radiation.

1. Genes that normally prevent cell division are a. tumor suppressors. b. transcription factors. c. proto-oncogenes. d. oncogenes. 2. The cause of p53-related cancers is a. failure to repair damaged DNA, allowing the cell to continue dividing. b. fetal cells that remain in a child or adult, dividing too frequently. c. continual expression of the telomerase gene, which keeps cells dividing. d. deletion of cell cycle checkpoint gene. 3. Cancer does not typically follow a Mendelian pattern of inheritance because it is usually caused by a. two gene variants, one dominant and one recessive, and no environmental input. b. specific combinations of alleles and an environmental factor. c. specific combinations of an environmental factor and one dominant gene variant. d. genes that cause death before birth.
