step 1:
making a copy (transcribing) of the DNA code for the needed protein
*occurs in the nucleus of the cell
*the section of DNA that codes for the needed protein unzips
*RNA polymerase is the enzyme that binds to regions on the DNA called "promoters" (specific DNA base sequences)
*it then begins to unzip the DNA section
*only one of the unzipped strands is used as a template/pattern
*this one strand contains the code for making the needed protein
*RNA nucleotides bond to the DNA strand that codes for the needed protein
*G bonds with C
*U bonds with A
*'T' on DNA will bond with 'A' on RNA
*once the RNA strand is completley made it moves away from the DNA strand
*the RNA strand is "edited" befor tit leaves the nucleus
*introns are the peices that are removed from the RNA strand
*exons are the pieces the are needed and are spliced together once the introns have been removed
*the edited RNA is now called "messenger RNA" and moved out of the nucleus into the cytoplasm
example:
DNA strand: GCTATGC
RNA strand: CGAUACG
