fraction-level $^{13}$C assimilation dynamics and membership differences}  % Fakesubsubsection:Techniques to identify $^{13}$C-DNA in DNA-SIP  Techniques to identify $^{13}$C-DNA in DNA-SIP studies (reviewed by CITE)  include %include  adding $^{13}$C carrier DNA to density gradients, visualizing density %density  gradient DNA with DNA intercalating dyes CITE, and screening density %density  gradient fractions with microbial community fingerprinting techniques %techniques  or qPCR CITE. $^{13}$C DNA and high G+C $^{12}$C-DNA occur at %the same buoyant density positions in the density gradient  %\citep{Buckley_2007}. Comparing control gradients with $^{13}$C labeled  %gradients differentiates $^{13}$C DNA from high G+C $^{12}$C DNA. High
