Then, they deleted various parts of the Wnt7a protein until they found the smallest part that was responsible for exosome-targeting. They called this part, which consists of 18 amino acids ...

Researchers from the Ottawa HospitalResearch Institute and the University of Ottawa in Canada, along with researchers from the Centre for Genomic Regulation at the Barcelona Institute for Science ...

Amino acids are small molecules that are the building blocks of proteins. Proteins serve as structural support inside the cell and they perform many vital chemical reactions. Each protein is a ...

Following this discovery, Nirenberg, Philip Leder, and Har Gobind Khorana eventually identified the rest of the genetic code and fully described which codons corresponded to which amino acids.
