    Hi, im having trouble on transcription, when the free RNA nucleotide align with the DNA template strand do they hydrogen bond to their complimentary base or do they just remain aligned and unbonded?

    From what I know the free RNA nucleotides form hydrogen bonds with the DNA template strand, then they are attached (polymerised) to the other RNA nucleotides and the strand being build up by the RNA polymerase enzyme, and then as RNA polymerase moves along the hydrogen bonds between the DNA strands are rebound and the RNA comes out - this might help http://www.chemguide.co.uk/organicpr...cids/dna3.html

    The transcription is a phase in genetics where three different RNA strnads are produced, namely m-RNA, t-RNA and r-RNA. These RNA strands are comlementary to DNA strands, that is to say the RNA strands matches to the DNA one. By creating the RNA strand, every single RNA nucleotide is bounded to DNA first, after creating the RNA those nucleotides - as an RNA strand - are leaving the DNA and are unbounded. Those created RNA strands are leaving the cell for protein biosynthesis in ribosomes.*

    Hope to have answered your question. **
