Agarose gel electrophoresis separates DNA and RNA molecules based on their size. 19 Nucleic acids are loaded into a gel matrix and an electric current is applied. Smaller molecules move faster through ...

What is DNA, and how does it work? You don't need a degree in genetics to understand. Here, we'll give an overview of DNA and ...

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 ...

Thus, RNA molecules play numerous roles in both normal ... hypothesis that an "RNA world" may have preceded the evolution of DNA and proteins (Gilbert, 1986). Small interfering RNAs (siRNAs ...

Membraneless organelles, also called biomolecular condensates, are changing how scientists think about protein chemistry, ...

Scientists have long wondered how the first cell membranes formed from the primordial soup—a new study offers up a recipe.
