I placed some of the DNA on the ends of my fingers and rubbed them together. The stuff was sticky. It began to dissolve on my skin. 'It's melting -- like cotton candy.' 'Sure. That's the sugar in the DNA,' Smith said. 'Would it taste sweet?' 'No. DNA is an acid, and it's got salts in it. Actually, I've never tasted it.' Later, I got some dried calf DNA. I placed a bit of the fluff on my tongue. It melted into a gluey ooze that stuck to the roof of my mouth in a blob. The blob felt slippery on my tongue, and the taste of pure DNA appeared.

She kept the boarding pass in her hand. She went looking for the blue concourse. She had to go downstairs to find it, and take one of those trains that was like an elevator that ran sideways.

She hadn't expected them to do that; she'd thought she could find a pay-station in the departure lounge, link up, and give the club an update. They never sealed her carry-on when she went to Vancouver to stay with her uncle, but that wasn't really international, not since the Agreement.She was riding a rubber sidewalk toward Gate 52 when she saw the blue light flashing, up ahead. Soldiers there, and a little barricade. The soldiers were lining people up as they came off the sidewalk. They wore fatigues and didn't seem much older than the guys at her last school."Shit," she heard the woman in front of her say, a big-haired blond with obvious extensions woven in.

A DNA sequence for the genome of bacteriophage ΦX174 of approximately 5,375 nucleotides has been determined using the rapid and simple 'plus and minus' method. The sequence identifies many of the features responsible for the production of the proteins of the nine known genes of the organism, including initiation and termination sites for the proteins and RNAs. Two pairs of genes are coded by the same region of DNA using different reading frames.
