Economic indicator. An economic indicator is a statistic about an economic activity. Economic indicators allow analysis of economic performance and predictions of future performance. One application of economic indicators is the study of business cycles. Economic indicators include various indices, earnings reports, and economic summaries.
Transduction (genetics) Transduction is the process by which foreign DNA is introduced into a cell by a virus or viral vector. An example is the viral transfer of DNA from one bacterium to another. Transduction does not require physical contact between the cell donating the DNA and the cell receiving the DNA (which occurs in conjugation), and it is DNase resistant (transformation is susceptible to DNase).
Specialized Transduction. The second type of transduction is called specialized transduction. In this process, instead of just hijacking and killing the cell, the viral DNA goes dormant by incorporating itself into the bacterial DNA chromosome.he first is called generalized transduction. In some cases, the bacteriophage interaction with the bacteria is quite simple-the virus invades, hijacks the host to generate copies of itself, then kills the host cell by popping it like a balloon (called lysis).
