We avoid direct inter-pair interference by imposing that each white subcarrier can be assigned to the one pair at the time (i.e., ∑ k = 0 K - 1 v ( k, i ) ≤ 1 ).
Single-molecule studies have confirmed structural and biochemical data indicating that RNA polymerase advances one base pair at a time as it incorporates one ribonucleotide during the synthesis of an RNA chain.
This was unexpected, because DNA synthesis occurs in steps of one nucleotide, which would require unwinding of only one base pair at a time.
