Which of the following statements supports the hypothesis that viruses can cause cancer?

A. Cancerous & normal cells share genetic sequences

B. Cellular DNA has sequences related to viral sequences

C. Genes that regulate cell division are found in some viruses

D. Viruses and cancer cells both replicate rapidly

Expert Solution

c, gennes that regulate cell division are found in some viruses.
d, virus and cancer cells both repicate rapidly.
Cancer occur when the genetic material within the DNA cell to divide uncontrollably. In the hypothesis process that virus cause cancer without integrating itself into cell DNA. cell develops genetic mutation but the virus in the cells override the defense mechanism and allow cells to live. when more genetic mutation develops that turn cell to cancerous.
viros will not cause cancer, but by application it causes cancer. cells have some defense mechanisms to prevent tumor growth, but virus interfere with this defense mechanism.
some virus take hit and run approach it cause cancer and then disappear. example: herpes virus can trigger cancer then disappear from cancer cells. the virus has genes that trigger cells to divide rapidly.
In general cancer cells have more genetic changes than normal cells.

1) Which of the following statements are true? If the null hypothesis is rejected at the 1% level of significance, then it will be rejected at 5% of level of significance. For a given confidence level, halving the margin of error requires a sample twice as large. For a specified confidence level, larger samples provide smaller margins of error. a) Ionly b) IIonly c) IIIonly d) IandIIonly e) IandIIIonly 2) Suppose that you take random samples of size n from...

A mutation in the ras cellular oncogene can cause cancer when it is in the heterozygous condition, but a mutation in the RB tumor suppressor gene can cause cancer only when it is in the homozygous condition. What does this difference between dominant and recessive mutations imply about the roles that the ras and RB gene products play in normal cellular activities?

Which of the following statements is false? When the alternative hypothesis is two-sided, any hypothesis test is said to be a two-tailed test When the alternative hypothesis is two-sided, the null hypothesis is rejected for values of the test statistic located in either tail of that statistic’s sampling distribution When the alternative hypothesis is two-sided, the rejection region is split between the two tails of the test statistic’s sampling distribution None of the above A social worker was interested in...
