encloses

These extremely reactive molecules always occur in pairs and remain surrounded by solvent, which encloses the pairs of radicals like a kind of cage.

It’s so stark, so subtle in how it encloses the space, turning it into a haven.

"We integrated many of the most advanced cryo-EM techniques available today with AlphaFold molecular modeling. This gave us, for the first time, a detailed overall view of the poxviral core-the 'safe' or 'bioreactor' inside the virus that encloses the viral genome and releases it in infected cells," says Schur.

This thin layer of lipids encloses nutrients, genetic material and proteins of the cell.

The satellite virus needs the helper either to build its capsid, a protective shell that encloses the virus's genetic material, or to help it replicate its DNA.
