A Case So Cold It Was Blue. The murder of newlywed Sherri Rasmussen went unsolved for 23 years, with the Los Angeles police assuming it was a burglary turned violent. Then, one morning in 2009, when a detective opened the cold-case file, he got his first clue that the killer had been under their noses the entire time. Mark Bowden gets to the core of the case, and the mystery that remains.
Genetic engineering (GE) is the modification of an organismâs genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species.

Genetic engineering is any process by which genetic material (the building blocks of heredity) is changed in such a way as to make possible the production of new substances or new functions.As an example, biologists have now learned how to transplant the gene that produces light in a firefly into tobacco plants.he term vector means any organism that will carry the gene from one place to another. The most common vector used in genetic engineering is a circular form of DNA known as a plasmid. Endonucleases are used to cut the plasmid molecule open at almost any point chosen by the scientist.
