The lactose gene segments of DNA were chemically complementary and combined easily into a double strand.
But since the two types of viral DNA were not oriented in complementary pairs, the viral DNA remained as loose, single strands.
By treating the DNA with a special enzyme that dissolves single-stranded DNA but does not effect double strands, the three researchers were able to separate the bacteria's lactose gene from the virus.
Coach Bill McCurdy is cautions but optimistic about his team, which also includes Mike Koerner, John Heyburn, Erik Roth, and Howie Foye. "We're not going to be in there for exercise." he said. Thursday. "We'll be a better team than we were in the IC4A's, but everything...
To extract this gene, the scientists took advantage of the fact that when a virus infects a bacterium it sometimes removes a piece of the bacterium's DNA. They infected E. coli with two types of viruses that were specifically bred to remove the lactose gene from E. coli.
