What is the relationship between the movement of the atmosphere and the movement of surface currents?

The surface currents and the lower atmosphere movements are connected to one another. Namely, the surface currents influence the temperature and the humidity of the air masses above them. Also, the movement of the surface currents to a certain direction is causing the movement of the air masses above them. So we have a situation where the surface currents with their properties influence the type of the air masses above them, as well as the direction of the movement of those air masses. Because of this it is very easy to predict the type and direction of movement of an air mass if we know the type and direction of movement of a surface current.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
