  • Escape from parental tissue

  • Colonisation of new tumor sitee

Explanation

Question 2 of 7

  • They skip the transformed cell step

  • They never get past the transformed cell step

Explanation

Question 3 of 7

  • DNA Polymerase

Explanation

Question 4 of 7

1

Why is viral integration so dangerous?

Select one of the following:

  • It makes the disruption of important genes more likely

  • It tampers with translation/transcription machinery

  • It prevents proteins from folding properly

Explanation

Question 5 of 7

1

Can viruses pick up human genes, and would it be dangerous?

Select one of the following:

  • 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

Explanation

Question 6 of 7

1

If a virus picked up only part of a gene, is this dangerous?

Select one of the following:

  • 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

Explanation

Question 7 of 7

If Src was to be overproduced, what would the effect be?

Select one of the following:

  • Debundling of vinalin

  • Debundling of laminin

  • Cells release surface and degenerate further
