21.   Analysis of samples from the women revealed genetic material from an arenavirus, one of a family of pathogens that have caused hemorrhagic fevers in Africa and South America.

22.   And that raises the possibility that a baby who inherits genetic material from the donor will pass it along to her own child, changing the course of heredity.

23.   Arber had discovered the type of restriction enzymes that dismantle genetic material at specific points.

24.   As in genomics, the study of the genetic material in the chromosomes unique to a specific organism, the accent is on the om.

25.   As the mutated cell remains in the bloodstream, it may accumulate other mutations and eventually pile up enough errors in its genetic material that it becomes cancerous.

26.   AZT, DDC and DDI jam an enzyme, called reverse transcriptase, which enables the virus to replicate by turning its genetic material from RNA into DNA.

27.   Besides disrupting target genes, the introns can be used to insert new genetic material into DNA.

28.   Biomedical cloning is distinct from reproductive cloning, the process by which a new human being might be grown from the genetic material of a single individual.

29.   A device that loads genetic material into a sequencer made by Visible Genetics and tests samples of infected blood.

30.   A DNA test could not distinguish between the genetic material left by the casual handler, Kolman said, and material left by a human ingredient.
