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 involves the mRNA, tRNA and rRNA coming together. The mRNA goes through the rRNA starting at the end identified as 5', or the end with A U G, and it will go all the way through to the terminating end. The terminating end is identified as 3'. tRNA will begin to join the other two strands starting with the A location.
