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
Scaffold strand diameter and surface properties can change how cells attach, migrate, and interact with a construct. Diameter contributes to the strand’s structural scale, while surface properties influence the interface presented to cells. Because these features also affect scaffold architecture, researchers tune them together to support suitable mechanical behavior, cellular organization, and tissue development.
Arrangement determines how individual strands contribute to the scaffold’s three-dimensional architecture. Bundling, weaving, and alignment can be adjusted to influence mechanical strength, porosity, and fluid transport, while also organizing the environment encountered by cells. Selecting among these configurations helps researchers reproduce structural features of native tissues and guide tissue formation within the construct.
Combining scaffold strands with hydrogels allows a construct to incorporate fibrous architecture alongside another biomaterial phase. This combination can help reproduce structural features of native tissues while providing additional opportunities to tune material properties and cell interactions. Researchers can therefore use mixed-material designs to support cell growth, tissue formation, and biomimetic scaffold development.
A design process can begin by selecting the strand composition and diameter, then adjusting surface properties and the overall arrangement. Researchers may bundle, weave, or align the strands, or combine them with hydrogels and other materials. These choices are coordinated to balance mechanical strength, porosity, fluid transport, cell behavior, and tissue-development goals.
Scaffold strands are useful when researchers need organized biomaterials for tissue-engineering constructs or other three-dimensional bioengineering designs. They support work on engineered replacements, regenerative therapies, and biomimetic devices. Their tunable architecture makes them relevant when a study must connect material structure with cell growth, guided tissue formation, or tissue-like organization.
Evaluation can examine mechanical strength, porosity, and fluid transport, along with cell attachment, migration, and interaction with the scaffold. Researchers can also assess whether the design supports cell growth and guides tissue formation. Together, these outcomes show how strand composition, dimensions, surface properties, and arrangement affect the construct’s intended bioengineering function.
