The cable consists of loose tubes (or some fillers) stranded around the central strength member, outside cable core, corrugated steel tape longitudinal folded and PE extruded as outer sheath. The tube is made of good temperature property material. A number of single or multi-mode fibers are secondary coated into the loose tube with suitable excess length and tube filled with moisture-proof compound. All the interstices of cable core are filled with water blocking compound.
An interphase chromosome lacks an obvious scaffold, but its looped domains seem to be attached to the nuclear lamina on the inside of the nuclear envelope, and perhaps also to fibers of pop over to the website the nuclear matrix.
