Genes on the - laser - firing line.Genes on the (laser) firing line Like a nail puncturing a tire, lasers apparently make tiny, self-sealing holes in cell membranes through which genetic material can enter, say scientists at the University of California The University of California has a combined student body of more than 191,000 students, over 1,340,000 living alumni, and a combined systemwide and campus endowment of just over $7.3 billion (8th largest in the United States). at Irvine. In the "laser-mediated gene transfer' technique, cells are irradiated with an yttrium-aluminum garnet laser beam while suspended in a liquid containing foreign DNA DNA: see nucleic acid. DNA or deoxyribonucleic acid One of two types of nucleic acid (the other is RNA); a complex organic compound found in all living cells and many viruses. It is the chemical substance of genes. . According to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. an article in the June PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES The Proceedings of the National Academy of Sciences of the United States of America, usually referred to as PNAS, is the official journal of the United States National Academy of Sciences. (Vol.84, No.12), the DNA is successfully incorporated into the genetic machinery of host cells. The authors suggest that the method may circumvent problems in standard DNA transfer techniques. |
