dna strands are parallel, running in the same orientation.
true
false
question 12 (1 point) ✓ saved
after initial infection, some infectious agents go into a dormancy, or , but may re-emerge to produce a recurrent disease state.
reservoir state
latency
symptomatic state
sequelae
question 13 (1 point) ✓ saved
which of the following is not an adhesion mechanism that bacteria use to attach to a host?
fimbriae attach to epithelium of host
glycocalyx anchors the microbe to the host
dextran slime layer glues the microbe to the host surface
envelope spikes puncture cells for entry

Explanation:

For Question 11: DNA strands are antiparallel, not parallel. One strand runs in the 5' - 3' direction and the other in the 3' - 5' direction.
For Question 12: Latency is the state where infectious agents go dormant after initial infection and can re - emerge.
For Question 13: Envelope spikes are for viral entry into cells (a different process than bacterial adhesion). Bacterial adhesion mechanisms include fimbriae, glycocalyx, and dextran slime layer.

Answer:

Question 11: False
Question 12: latency
Question 13: envelope spikes puncture cells for entry
