Question
It is common to see one or two diffuse (fuzzy) bands of RNA and/or primer dimer at the bottom of the gel after
PCR amplification. RNA may be found at approximately the position of the smallest fragment of the
PBR322/BstNI marker you used alongside your samples you loaded. RNA is the largest component of nucleic
acid isolated from plant tissue, so some RNA may escape digestion by the RNase incorporated into the TE
buffer in Part Il of the experiment. Primer dimer is an artifact of the PCR reaction that results from two primers
overlapping one another and amplifying themselves. Where do you expect to see bands of Primer dimer
and/or RNA, if present, on your gel?
A. approximately 50bp and 121bp fragment of the marker
B. below 121bp fragment of the marker
C. between 121-383bp fragments of the marker
D. none of these
