double helix betydelse and definition

Exempel på double helix

• Writhe relates to how many times the axis formed by the double helix crosses over itself, forming a supercoil.

• Writhe is a highly compacting manifestation of linking number deviations since it represents the winding of the double helix upon itself.

• The first prerequisite is the presence of a sequence that can fold back on itself to form a paired double helix.

• First, the zinc fingers exert non-specific interaction with the backbone of a double helix whereas the second mode allows zinc fingers to specifically recognize the individual bases that bulge out.

• The information contained in a double helix is no different in kind from that exhibited in the linear sequence of bases.

• Interacting ions modulate this interaction : stabilization and destabilization of the double helix is more complex than simple charge neutralization.

• What is certain is that published research and other evidence at all levels should feed into this process, in order to maintain the double helix of innovation and generalizability.

• Many forms of the open state are possible for a single base pair, although a preference for opening towards the major groove of the double helix has been found.
