Miming the darts or melting force of love, or the dialogue with birds, she was keenly focused.
Intel's microprocessors were generating so much heat that they were melting, forcing Intel to change direction and try to add computing power by placing multiple smaller processors on a single chip.
The Arctic is feeling the impact of global warming more than any other place on Earth and the bears' hunting grounds and migration routes are melting, forcing them to swim for dozens of miles in search of solid ground.
Full-length α protein does not lower the melting force but inhibits reannealing of DNA that has been melted by force.
In addition to ssDNA binding, a very slight increase in the melting force is observed in Figure 4, panel a.
For example, both T4 gp32 and T7 gp2.5 lower the DNA melting force in real time as the DNA is being stretched, such that the observed melting transition force is lowered in the presence of the protein (28, 29).
Proteins that actively bind to ssDNA generally lower the observed melting force as the protein helps to stabilize ssDNA relative to dsDNA (27– 27).
To quantify this effect, we measured the melting force at the approximate midpoint of the transition (averaging the observed force over the extension range of 0.44−0.46 nm per base pair).
Whereas binding to dsDNA is observed to stabilize the helical form, binding to ssDNA destabilizes the double helix and is manifested in the data as a decrease in either the melting force or the length of the overstretching plateau (24– 24).
Then, 100 nM full-length α protein or 500 nM α1−917 was added, resulting in a strong increase in the melting force, indicating dsDNA binding, whereas α1−917 shows little binding to ssDNA (see below). Figure 5, panel c summarizes this data over a range of salt concentrations and shows dsDNA stabilization that is independent of salt concentration within uncertainty.
