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).
Conjugation and Plasmids In a process called conjugation, genetic material is transferred between two bacterial cells (of same or different species) that are temporarily joined. The DNA transfer is one way: One cell donates the DNA,a nd the other receives ti.The donor uses sex pili to attach to the recipient.he cell is now a recombinant: Its chromosome contains DNA derived from two different cells. In transduction, bacteriophage carry bacterial genes from one hose cell to another; transduction is a type of horizontal gene transfer.
