Transcription occurs in the ____________ of a cell. It starts with (A) ______ _______________ racing along (B)_____ strands looking for _____________ factors that have bound to the (B) at the promoter (another word for the promoter is the (D)__________ box). The (A) attaches to the (B) at the (D) box, which is ____ (#) base pairs upstream from the start of the (E)__________. All (E) start with the sequence _______ in their ________ strand. The (A) pulls the two strands apart, counts to _______(#), and then uses the _________ strand as a template to make a _______-stranded copy of the _______ strand (this new strand is called (F)_______). The only difference between the (F) strand and the ________ strand of (B) is that the (F) replaces __________ with _________. The (F) is further processed by adding a 5’_________ (made of a __________ nucleotide hooked on backwards) and a 3’ ________ ____ tail (made of about 200 ____________ nucleotides) to protect the (F) from _____________. Once the (F) is processed, it moves into the _________________ where translation occurs.
