Some of the embryos took up the abnormal gene fragment in their chromosomes.

Under the new guidelines expected to take effect in the next few months, gene fragments will probably not qualify for patents.

Some experimental work showed that the gene fragment was switched on in the brain.

He pointed out that other countries were garnering gene fragments but had made no commitment to publish them.

In first section, definitive identification of variation is obtained by nucleotide sequence determination of gene fragments.

This implies that the gene fragment leads to the expression of an odor or pheromone that the mice can detect.

The N.I.H. must prove that the gene fragments are useful and that, in finding them, human invention was involved.

It then multiplies these gene fragments so they can be detected.

This was based on anatomical characters and a dataset of molecular sequences of three gene fragments.

The chip is essentially a microscope slide spotted with gene fragments from 1,000 viruses.
