The translation is initiated as the
small ribosomal subunit muddles to the mRNA. Then
the tRNA having the methionine binds to the start codon, and the large ribosomal subunit binds to the insignificant one.
Finally, t<span>he start codon indicates the start of
translation.</span>
The photo with the smoke emitting from the cars will increase the carbon dioxide in atmosphere by directly adding carbon dioxide (as well as other compounds such as sulfur and carbon monoxide). The photo that says "switch off" reduces consumption of electricity, which if done collectively, may reduce the burning of fossil fuels thereby reducing the carbon dioxide in atmosphere.
