Improvements to NCBI Assembly
NCBI’s genome Assembly has a number of significant improvements!
Assembly records now have a link to Primer-BLAST making it easy to design primers in the context of a specific eukaryote genome assembly. Figure 1 shows the Assembly page for the Genome Reference Consortium Mouse Build 39 (GRCm39) with the link to Primer-BLAST.
Figure 1. The Assembly page for the mouse reference genome (GCF_000001635.27). Showing the new Run Primer-BLAST link, which loads the assembly as a database in the Primer-BLAST search (bottom) and the new expandable note sections, Genome-Annotation-Data in this case.

View intron feature evidence in the Genome Data Viewer and Sequence Viewer
Are you a researcher who works on gene biology and are interested in alternative splice patterns in your gene or genes of interest? If so, be sure to explore the intron feature evidence available in graphics views of genome assemblies annotated by NCBI. You can view the NCBI evidence used for calling splice variant for genes, add other intron feature evidence tracks, and use new display and filter options that make it easier to interpret the data .
Figure 1. Graphical view of the monoamine oxidase gene (MAOA, MOAB) region on the human X chromosome showing intron features tracks (‘RNA-seq intron features, aggregate’ and ‘Intropolis RNA-Seq intron features’). Mousing-over an intron feature activates a tooltip that shows details such as the number of reads with the splice site, the location on the chromosome, the length of the intron and the donor and acceptor bases at the splice site. The Intropolis track was added through the search feature of the Configure Tracks menu and configured (bottom menu) so that the features were sorted by strand and filtered so that only features with greater than 500 reads appear.
