Hydrogen bonds can form with bases on the opposite DNA strands in the double helix, or between the bases and H2O in the single stranded conformation. Considering that the double helix is the most stable conformation in water, how does this observation support the conclusion that base stacking contributes more to helix stability than interbase hydrogen bonding?Hydrogen bonds can form with bases on the opposite DNA strands in the double helix, or between the bases and H2O in the single...

A summary of 150 words.. Can A Soda Tax Save Us From Ourselves? AS governments large and small face sizable budget shortfalls, policy makers are looking for ways to raise tax revenue that will do the least harm and, perhaps, even a bit of good. One idea keeps popping up: a tax on soda and other sugary drinks. The city council in Washington recently passed such a tax. Gov. David A. Paterson has sought one in New York. And a...

Ricin is a protein that can be isolated from castor beans. In pure form, ricin is extremely poisonous when inhaled or injected. Ricin can bind to eukaryotic ribosomal subunits and cleave them, making them inactive and ultimately preventing their action. a. What is the general structure of a ribosome? b. What biological process is inhibited by ricin if ribosomes are destroyed? c. Describe the steps of the process named in part b from initiation to termination

The human brain is the world's fastest computer. It can process information from a simple reflex, like lifting your hand away from a hot stove, or more complex tasks, like taking the visual and auditory information associated with a movie or play and interpreting it into a coherent story. The basic machinery that does this is the same. Let's discuss the structure of the neuron, and explain how a nerve impulse is transmitted. Be as detailed as you can
