In the context of the NIH Guidelines for Research Involving Recombinant DNA Molecules, recombinant DNA molecules are defined as either: molecules that are constructed outside living cells by joining ...
In these early electron micrographs, the DNA molecules appear as "trunks," with many RNA "branches" extending out from them. When DNAse and RNAse (enzymes that degrade DNA and RNA, respectively ...
the tree branches (granular strings attached to the DNA) are RNA molecules that have been transcribed from the DNA. As the transcription apparatus moves down the DNA, transcribing more of the ...
