Rapid CRISPR-Cas13a genetic identification enables new opportunities for listed Chinook salmon management

Accurate taxonomic identification is foundational for effective species monitoring and management. When visual identifications are infeasible or inaccurate, genetic approaches provide a reliable alternative. However, these approaches are sometimes less viable (e.g., need for near real-time results, remote locations, funding concerns, molecular inexperience). In these situations, CRISPR-based genetic tools can…

New gene-edited tomatoes boost vitamin D levels

An international team of scientists primarily based out of the John Innes Centre in the United Kingdom has used gene-editing to create a vitamin D-enriched tomato. Using CRISPR-Cas9, they switched off an enzyme in tomatoes that ordinarily prevents the molecular forerunner of vitamin D3 (called 7-dehydrocholesterol, or 7-DHC) from accumulating…

biopython – Pipeline for paired end RNA sequence data to proteins

This is a much more complicated question than it might seem. First, you need to understand how RNA-Seq works, and what your data really is. Your “paired-end files” contain reads, which will contain fragments of transcripts. Since those are only fragments of transcripts, you don’t know what frame they are…
