(CNN)Mourners held a heavenly birthday memorial Sunday for Victoria Martens, the 10-year-old New Mexico girl who Albuquerque police say was raped by her mother's boyfriend and then killed while her mother watched.
RNA interference (RNAi) is a natural process that cells use to 'turn off' or silence unwanted or harmful genes. The initial discovery of this phenomenon was in 1991, by scientists trying to deepen the colour of petunias. Surprisingly, by introducing a gene for colour, they found that they had turned off the gene.
RNAi Overview. RNA interference (RNAi) is a relatively new technology that is revolutionizing the way that researchers study mammalian gene expression. RNAi has had significant impact on the ease, speed, and specificity with which the loss of gene function analysis can be done in mammalian cells and animal models.This is becoming the method of choice for researchers doing loss of function studies. brief history of RNA interference (RNAi). Figure 1. Evolution of RNAi. RNA Interference (RNAi) is one of the most important technological breakthroughs in modern biology, allowing us to directly observe the effects of the loss of function of specific genes in mammalian systems.
