DNA HELICASE - breaks hydrogen bonds between bases in a specific region of the DNA. These two strands separate and unwind, exposing nucleotide bases. , RNA POLYMERASE - binds to the template strand of DNA at the beginning of the sequence to be copied. , FREE RNA NUCLEOTIDES - align opposite template strands based on the complementary relationship between bases in DNA and free nucleotides. Eg. Cystosine with Guanine., RNA POLYMERASE - moves along the DNA forming bonds forming a RNA strand. , The RNA polymerase - separates from the template strand when it reaches a ‘stop’ signal. , The production of the transcript is complete and the newly formed RNA detaches from the DNA. .
