Transcription
Gene unwinds and unzips. Hydrogen bonds break. RNA binds onto the TEMPLATE STRAND. 2 extra phosphyl groups released for energy. mRNA exact copy of base sequence of CODING STRAND. Passes through nuclear pore to ribosome.

tRNA structure
Lengths of DNA folded into hairpin shapes. 3 unpaired bases at one end where a.acid joins. Anticodon, which binds to complementary codon on mRNA.
