Their report, published in the Proceedings of the National Academy of Sciences, offers an unprecedented view of the sequence of hydrogen-bonding events that occur when a protein morphs from an ...

Spiders don’t just spin webs—they engineer them. By stretching their silk as they spin, spiders strengthen the fibers at the ...

Spider silk is one of the most fascinating natural materials known to humans. It is more flexible than rubber yet tougher ...

For their analysis, the team focused on hydrogen bonds, which are weak bonds that the protein forms internally between the atoms in its amino acids and with the water surrounding it. These bonds are ...

When they weave their webs, spiders pull their silk threads. New simulations show stretching during spinning causes the ...

Nature ion channels play significant role in the living organisms, which can translocate physiological relevant ions across ...

A new study has unveiled the potential of hydrogen-bonding crosslinked supramolecular polymer materials derived from N-acryloyl glycinamide (NAGA).

Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA ...

This process of protein synthesis occurs in two stages ... The two strands of the DNA helix are unzipped by breaking of the weak Hydrogen bonds between base pairs. This unwinding of the helix ...
