extraction of gold by transgenic bacteria

Isolating, Cloning, and Sequencing DNA Molecular Biology

Isolating, Cloning, and Sequencing DNA Until the early 1970s DNA was the most difficult cellular molecule for the biochemist to analyze. Enormously long and chemically monotonous, the string of nucleotides that forms the genetic material of an organism could be examined only indirectly, by protein or RNA sequencing or by genetic analysis.

Making Medicines Understanding Genetics

Making Medicines. It's called gene pharming. For example, antithrombin III, which prevents blood clotting during surgery, is secreted in the milk of transgenic goats. To create these transgenic goats, scientists used a needle thinner than a human hair to inject the DNA sequence for antithrombin III into goat eggs.

During DNA extraction, all of the DNA from the organism is extracted at once. This means the sample of DNA extracted from the Bacillus thuringiensis bacteria will contain the gene for the Bt protein, but also all of the other bacteriums genes. Scientists use gene cloning to separate the single gene of interest from the rest of the genes extracted.
