Page 7: Research news on DNA sequencing

DNA sequencing is a set of laboratory methods for determining the precise linear order of nucleotides (A, C, G, T) in a DNA molecule. Core methodological classes include Sanger sequencing, which uses chain-terminating dideoxynucleotides and capillary electrophoresis for high-fidelity, low-throughput analysis, and next-generation sequencing (NGS) platforms, which employ massively parallel sequencing-by-synthesis, sequencing-by-ligation, or nanopore-based readout for high-throughput, genome-scale applications. These methods entail library preparation, clonal or single-molecule amplification (except in true single-molecule approaches), signal detection, and computational base-calling, followed by quality control and downstream bioinformatic analysis.

Improving oats for growers and consumers

Heart-healthy oats are finding their way into a wider variety of products and recipes as consumer demand grows. Although oats are grown on far fewer acres than other U.S. crops, farmers are able to keep up with demand through ...

Ancient DNA reveals Ice Age humans targeted female woolly mammoths

Analyzing ancient DNA from more than 500 mammoth bones, an international team of researchers found that Ice Age humans selectively targeted female woolly mammoths. The results of the study, published in Current Biology, show ...
