Fixing Double-strand Breaks

The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

We describe an efficient method to separate single-stranded DNA, double-stranded DNA and RNA molecules from environmental viral communities. Nucleic acids are fractionated using hydroxyapatite chromatography with increasing concentrations of phosphate-containing buffers. This method permits the isolation of all viral nucleic acid types from environmental samples.
FAQs
The solid shell provides the strand’s initial structural strength while liquid metal remains inside. It forms against the water-cooled mold and must become sufficiently stable before the strand is withdrawn through later cooling zones. If shell formation does not match the casting conditions, the partially solidified section may be vulnerable to defects, making temperature, flow, cooling rate, and casting speed important control variables.
These variables control how quickly the shell develops and when the liquid core reaches complete solidification. Their coordination supports consistent section dimensions and helps prevent defects. Casting conditions also determine whether the strand is suitable for later rolling or forging, so process control links the behavior inside the mold and cooling zones with the quality of the finished semi-product.
Compared with separate ingot casting, strand casting produces sections continuously and cuts them to the required length after solidification. This reduces the need for an additional sequence centered on individual ingots and supports improved productivity, dimensional consistency, and material yield. The resulting slabs, blooms, or billets can move into downstream rolling or forging operations.
A typical sequence begins when molten metal enters a water-cooled mold and develops an outer shell. Withdrawal rolls then move the partly solidified strand through secondary cooling zones, where solidification continues until completion. The fully solidified product is cut to length and prepared as a slab, bloom, or billet for subsequent manufacturing.
The essential equipment identified for strand casting includes a water-cooled mold, withdrawal rolls, secondary cooling zones, and a cutting stage. Their operation must be coordinated with molten-metal temperature, flow, cooling rate, and casting speed. Together, these components control shell formation, strand movement, final solidification, section dimensions, and readiness for downstream processing.
Engineering production uses strand casting for steel, aluminum, and other metals when continuous manufacture of solid sections is advantageous. The process supplies slabs, blooms, and billets that serve as feedstock for later rolling or forging. Its practical value lies in combining high productivity with dimensional consistency and improved material yield before those downstream manufacturing steps.
