Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

New evidence on how proteins help cells fix broken DNA

Aucott et al. report the first in vivo experiments on the heterochromatin protein 1 (HP1) family, which sidles up to silent DNA.

New molecular insight into vertebrate brain development

In the December 1st issue of G&D, Dr. Fred H.
