I am confused about this DAT destroyer question

119. Which statement is false?
A) prokaryotes reproduce by binary fission
B) blue green algae are found in kingdom plantae
C) Circular DNA molecules that exist in bacterial cells are called plasmids
D) Multiple DNA copies can be made by PCR technique
E) Most accurate way to work out molecular structures is X ray diffraction

I thought all genetic material of bacterial cells were circular. Is it only plasmids?

Plasmids is only bacteria that is circular and it is a vector DNA

Whats the correct answer? I chose E, you can also do NMR?

B is false because bacteria are from monera

NMR determines information on the local conformation and distance between atoms that are close to each other. Think small: like the orgo problems you do for NMR for the DAT.

X-Ray crystallography results in an X-Ray diffraction pattern, which is considered the standard for determining molecular structures. That's really all you need to know for the DAT, so I'm not going to try to complicate things further.
