7.012: Introductory Biology-Fall 2004 Instructors: Professor Eric Lander, Professor Robert A. Weinberg, Dr. Claudette Gardel Big Idea 1: Biology is based on observational and experimental science. 1. We think what we think because we can draw conclusions from the results of controlled experiments. 2. An informative experiment is designed to distinguish between hypotheses

Notes LECTURE Biochemistry 9.17.04 ATP is both a unit of energy currency in a cell and a building block of RNA. Why? It is believed that early in evolution there were very few molecules around. Many key pathways are ancient, and trace their origin to the early stages of evolution of life on Earth. Incidentally, such pathways are usually highly conserved in modern organisms. This is probably because once

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
