Document Summary
In the figure above is a segment of ds dna, known as a gene. The gene is read from the 3" end, which contains a phosphate, to the 5" end, which contains ribose. There are two strands that run antiparallel, meaning one is from 5" 3" and the other is next to it 3" 5". The red block is the part of the dna that will be copied. The proximal promoter is about 500 base pairs or so ahead of the 5" end of the gene sequence to be transcribed and translated by mrna. This proximal promoter is the core promoter that binds the general transcription machinery, including the rna polymerase core enzyme and other general transcription factors. After transcription-- the synthesis of messenger rna from a dna template through the formation of base pairs, resulting in a transfer of genetic information that codes for amino acid sequences composing proteins translation occurs.
