At higher latitudes, climates become cooler warmer drier wetter

The latitude describes the location of a place north and south of the equator and which can be expressed in terms of angular measurements ranging from the 0° at the equator to 90° at the poles. Different latitudes receives different amount of sunlight. This is responsible for the variation in the climatic conditions. The higher latitudes receives lower amount of sunlight as compared to lower latitudes, therefore, the climatic condition of the higher latitudes is expected to be cooler than lower latitudes.  

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.
