Thus, the results indicate that RPrtc engaged in synthesis of RNA products up to at least 50 nt in length exhibits only 1 bp of DNA scrunching, whereas RPitc engaged in synthesis of RNA up to 8 nt in length exhibits up to 6 bp of DNA scrunching.

WebThe DNA spontaneously underwent scrunching motions, without being pushed or pulled by protein levers. This provides the first support for the scrunchworm model. It is essential to test the scrunchworm model experimentally, and Harvey has formed a collaboration with two other research groups to test predictions made by the scrunchworm model.

These stresses allow the ITC to store some of the excess free energy [−3 kcal/mol ( 39 )] of hydrolysis of the high-energy NTP phosphate bond and PP i release not expended in RNA synthesis.
WebMar 20, 2014 · The reduced DNA scrunching together with the absence of promoter rotation in the 4–6 nt RNA range in P266L suggests that the growing hybrid is accommodated by an alternative pathway.
