Despite its utility, PCR’s main limitation is that it requires precise cycles of heating and cooling to amplify DNA. The thermal cyclers that perform this operation are clunky, relatively expensive, ...

Plants have evolved a variety of defense mechanisms against predators and environmental challenges. Among their protective devices are a myriad of compounds, some very complex in structure, that allow ...

Testing for COVID-19 continues to be one of the most important tools in the global fight to slow and reduce the impact of the pandemic, particularly until vaccines are more widely available. Regular ...

What is multiple cross displacement amplification? Multiple cross displacement amplification (MCDA) method uses random primers and DNA polymerase to amplify the circular DNA template. The DNA can be ...

Quantitative polymerase chain reaction (qPCR) is a molecular technique that has reshaped the landscape of biological research and medicine due to its high sensitivity and specificity. qPCR, also known ...

Limited sample material resulting in insufficient DNA input is a common hurdle for downstream analysis. This problem can be solved using a variety of methods, including techniques that utilize ...

Promising new inroads into critical DNA testing has been forecast by experts who have applied machine learning to DNA profiling. From medical diagnostics to forensic tests and national security, PCR ...

Scientists in Japan have developed a way of amplifying DNA on a scale suitable for use in the emerging fields of DNA-based computing and molecular robotics. By enabling highly sensitive nucleic acid ...
