WHAT exactly happened to two Black Harvard students around 9 p.m. last Tuesday night remains muddled. Witnesses say the pair had run to catch a University shuttle bus when, upon boarding, several police cars blocked the van and a Black police officer shined a flashlight in their faces and ordered them to get off. The pair were then searched without explanation and, after officers found nothing, were left without notice of why they were stopped, the students...
...what a wondrous string it is. As Watson and Crick discovered in 1953, DNA consists of a double helix, resembling a twisted ladder with sidepieces made of sugar and phosphates and closely spaced connecting rungs. Each rung is called a base pair because it consists of a pair of complementary chemicals called nitrogenous bases, attached end to end, either adenine (A) joined to thymine (T) or cytosine (C) attached to guanine...
Tracking down the location of a gene requires tedious analysis. But it is sheer adventure when compared with the task of determining the sequence of base pairs in a DNA chain. Small groups of scientists, working literally by hand, have spent years simply trying to sequence a single gene. This hands-on method of sequencing costs as much as a dollar per base pair, and deciphering the entire genome by this method might take centuries...
...solution is automation. "It will improve accuracy," says Stanford's Paul Berg. "It will remove boredom; it will accomplish what we want in the end." The drive for automation has already begun; a machine designed by Caltech biologist Leroy Hood can now sequence 16,000 base pairs a day. But Hood, a member of the Genome Advisory Committee, is hardly satisfied. "Before we can seriously take on the genome initiative," he says, "we will want to do 100,000 to a million a day." The cost, he hopes, will eventually drop to a penny per base pair...
...cuddly Bernadette Peters in sadly deflated condition) is a designer of funky hats who suffers from a possibly justifiable weakness of the ego. She lives with a graffiti artist named Stash (Adam Coleman Howard) who has a definitely unjustified air of superiority. Before they finally break up, this tedious pair go to many noisy parties and performance-art evenings. Along the way, art-world fights, flirtations and fornications are noted but not explored in a script that is always lumbering off up aimlessly false trails. Indeed, many characters are written so dimly that it is often hard to tell...
