Solved A researcher sequences a DNA fragment using

Transcribed image text: A researcher sequences a DNA fragment using dye-terminator sequencing. In this procedure, each dideoxynucleotide triphosphate (ddNTP) contains a fluorescent marker specific to the base. Upon excitement by a laser, the ddNTPs emit light at their characteristic wavelengths. An automated machine then reads the sequence. In this procedure,…

Terminator Upgrades Single-Cell RNA Sequencing Technology

Japanese scientists have developed a new method for DNA amplification and sequencing that improves the accuracy of single-cell RNA sequencing (scRNA-seq). The new method called TAS-Seq uses a terminal transferase enzyme that amplifies and sequences DNA complementary to mRNA (cDNA) in solid phase on a nanowell/magnetic bead-based cell isolation platform….
