The study of genomics has revolutionized our understanding of science, but the field of transcriptomics grew with the need to explore the functional impacts of genetic variation. While different tissues in an organism may share the same genomic DNA, they can differ greatly in what regions are transcribed into RNA and in their patterns of RNA processing. By reviewing the history of transcriptomics, we can see the advantages of RNA sequencing – using a full-length transcript approach – become clearer. Reaching for the Transcriptome Even before genome sequencing became commonplace, scientists were able to measure gene expression activity using hybridization…
Welcome to the Sequencing 101 blog series – where we will provide introductions to sequencing technology, genomics, and much more! If you’re not immersed in the field of DNA sequencing, it can be challenging to keep up with the rapid evolution among all the platforms and technologies on the market. Let’s start with a quick overview of how these different technologies came about — and how each is used today. The evolution of sequencing technology. First Generation Sequencing – Starting the Era of Genomics The process of Sanger sequencing. DNA sequencing as we know it originated in the late…
Two years ago, Carola Greve and colleagues at the Zoological Research Museum Alexander Koenig in Bonn, Germany, were seeking to #SeqtheSlug as part of the 2017 Plant and Animal SMRT Grant competition, and the popular project was a close runner-up. Greve didn’t give up on her quest to sequence the ‘solar-powered’ sea slug. We caught up with her recently at the SMRT Leiden Scientific Symposium, where her update on the sea slug project earned her a Best Poster award. Why the sea slug? Although Mollusca represents the second largest animal phylum with around 85,000 extant species, only 23 mollusc genomes…
What can a cute, cuddly, stingless bee from the Brazilian rainforest teach us about eusociality and mitochondrial evolution? Natalia S Araujo wants to find out, and she’s not the only one. As the only bee species in which true polygyny (multiple fertile queens in the same colony) occurs, there is great interest in Melipona bicolor, and its mitochondrial genome (mt genome) was one of the first sequenced in bees. But the sequence was incomplete and lacked information about its mitochondrial gene expression pattern. So Araujo, a postdoctoral researcher of animal genomics in the GIGA Institute of the University of Liège,…
The PacBio team was honored to have the opportunity to give several talks at this year’s Advances in Genome Biology & Technology conference. If you weren’t able to be there, we’ve got you covered with videos and highlights. In a plenary session, Marty Badgett, senior director of product management, gave attendees a look at the latest results using the HiFi reads with the circular consensus sequencing (CCS) mode as well as a sneak peek at data from our soon-to-be-released Sequel II System. As he demonstrated, HiFi reads cover the same molecule many times, delivering high consensus accuracy (Q30 or 99.9%)…
