The researchers inserted a fluorescent sensor into bacterial cells so that the cells would glow green when sigma B sprang into action.

First, researchers took skin cells from the Alzheimer's patient and inserted the gene that makes nerve growth factor.

To find the gene, researchers inserted plant DNA into genetically engineered yeast cells that had lost much of their ability to take up potassium.

As with the mouse, the researchers inserted a bacterial gene that leads to the production of the enzyme.

Other researchers are inserting pest-control genes into plants.

Microstructural analysis: In the single-unit recording technique, researchers insert a tiny electrode into the brain to monitor the activity of a single cell.

When the researchers inserted such needles into a large nerve just above the inside of the elbow of human volunteers, "we found a surprise," he said.

The researchers inserted RNA sequences that also formed base paired structures.

The researchers then inserted testosterone-releasing pellets under the skin of the testosterone-deprived mice.

The researchers then inserted a number of obscenities and vulgarities in the standard lineup.
