Knowing what parts of the sequence adopt α–helix or β–strand secondary structure is an important part of almost all protein structure prediction methods. Because of its success at CASP2 ...

to argue that DNA actually takes the form of a double helix, a ladder-like structure that is twisted along its entire length (Figure 6). Franklin, Watson, and Crick all published articles ...

Scientists still needed to figure out this molecule's structure to be sure, and to understand how it worked. In 1948, Linus Pauling discovered that many proteins take the shape of an alpha helix ...

But where and how does the famous double helix fit into chromosomes ... Shown here is the structure of naked DNA -- DNA without all of the proteins that organize it into chromatin.

A structural protein is one that makes up the structure ... These amino acids form three strands, which make up the triple-helix structure characteristic of collagen. Collagen is found in ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... which is then translated into proteins. This process is ...

The two strands of the DNA helix are unzipped ... the correct shape and becomes a protein. Peptide bonds form between the adjacent amino acids to finalise the structure.
