Winds and wind systems on the Earth. 1  Wind is formed by the flow of air in horizontal directions. In meteorological definitions the coming direction of the wind is called wind direction. 2  1 m/s = 3.60 km/hr = 2.24 mph = 1.94 knot.
The production of proteins involves two major steps: transcription and translation. Together, transcription and translation are known as gene expression. The process of transcription only involves two molecules: DNA and RNA. A DNA strand provides a template for the synthesis of a complementary RNA strand. This process is used to synthesize any type of RNA from a DNA template. Transcription of a gene produces a messenger RNA (mRNA) molecule.
Translation requires several enzymes and factors for the process. It has mainly three steps, initiation, elongation and termination each of which requires a set of RNAs, cofactors and enzymes. Siteâ Transcription generally occurs in the nucleus where the transcription factors and enzymes are available. Translation on the other hand occurs in the cytoplasm after the primary mRNA transcript is transferred from the nucleus to the cytoplasm.
