Question 1

Question
Which step of metastasis is the easiest?
Answer
  • Travel in the bloodstream
  • Escape from parental tissue
  • Colonisation of new tumor sitee

Question 2

Question
What is special about virus induced cancers?
Answer
  • They skip the transformed cell step
  • They never get past the transformed cell step

Question 3

Question
RNA viruses require what to be infectious?
Answer
  • Reverse Transcriptase
  • DNA Polymerase
  • DNA Helicase

Question 4

Question
Why is viral integration so dangerous?
Answer
  • It makes the disruption of important genes more likely
  • It tampers with translation/transcription machinery
  • It prevents proteins from folding properly

Question 5

Question
Can viruses pick up human genes, and would it be dangerous?
Answer
  • Yes- they would cause over-expression of the gene as they replicated
  • Yes- they would potentially gain the ability to better survive inside the cell
  • No

Question 6

Question
If a virus picked up only part of a gene, is this dangerous?
Answer
  • Potentially more so than a whole one- a protein that worked but had no control domains would be very dangerous
  • Yes, but less than a whole one- the protein would not function as well
  • No- viruses cannot pick up genes
  • No- the protein wouldn't function

Question 7

Question
If Src was to be overproduced, what would the effect be?
Answer
  • Debundling of vinalin
  • Debundling of laminin
  • Cells release surface and degenerate further
