Many intracellular proteins are required to interact or bind to other macromolecules within a bind DNA. Such proteins often have conserved structural features, called motifs, whis at can cell in order to function properly. One class of such proteins is comprised of proteins tha interact with DNA. One such motif consists of two closely aligned a-helices(shown as cylinders below)that each have leucine-rich regions. This motif is referred to as a leucine

Cheese is a very varied group of dairy products, produced mainly in Europe, North and South America, Australia and New Zealand and to a lesser extent in North Africa and the Middle East, where it originated during the Agricultural Revolution, 6000-8000 years ago. Cheese production and con- 10A and 10B), is increasing in traditional

It was among the first proteins to be crystallized, and since crystallizability was long considered to be a good criterion of homogeneity, B-Ig, which is a typical
