Two terminators in prokaryotic genes one that terminates translation and one that terminates transcription. Transcription with the end product of an rna molecule (single stranded polynucleotides made up on nucleotides c, a, u and g) Transcription involves a complicated enzyme known as rna polymerase which is an enzyme catalyst that we can describe the biochemical reaction that it participates in. One of the substrates is a strand of dna, rna polymerase is enzyme and the catalytic activity of enzyme results in a single-stranded rna molecule. Double stranded dna molecule is regenerated and not changing we can have low amounts of it to start; the concentration of those nucleotides are decreasing in the cell as rna is using them up. Rna is synthesized from a dna template (template strand) Base sequence of rna is complementary to dna template.
