Page 2: 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.

DNA 'flight recorder' traces embryonic development cell by cell

For decades, scientists have been able to look at individual moments in the development of an embryo: a snapshot of a developing brain, a picture of how the heart takes shape or a glimpse of cells beginning to form the nervous ...

Mapping how a single cell becomes an entire mouse

Growing inside each of us is a cellular family tree. Every one of the 37 trillion cells in our body is generated from another cell, going all the way back to a single fertilized egg. Much like we can draw a family tree tracking ...
