From DNA to Protein

2509

Nucleotides in DNA are copied into RNA, where they are read three at a time to encode the amino acids in a protein. Many parts of a protein fold as the amino acids are strung together. Crabtree + Company View Media

Computer sketch of bird-and-flower DNA origami

Nucleosome

2741

Like a strand of white pearls, DNA wraps around an assembly of special proteins called histones (colored) to form the nucleosome, a structure responsible for regulating genes and condensing DNA strand Karolin Luger, Colorado State University View Media
