Every time a cell divides it makes a carbon copy of crucial ingredients, including the histone proteins that are responsible for spooling yards of DNA into tight little coils. When these spool-like proteins aren't made correctly, ...

In order to build and maintain cells, DNA is copied into ribonucleic acid (RNA) molecules, also called transcripts. Transcripts are often like a recipe for making proteins, and a collection of all the transcripts in a cell ...
