Exploring a genomic region in Gallus gallus (Chicken)

  1. Go to the region from 38,111,022-38,265,293 on chicken chromosome 5. How many contigs make up this portion of the assembly (contigs are contiguous stretches of DNA sequence that have been assembled solely based on direct sequencing information)?

  2. Zoom in on ESRRB gene.

  3. Turn on the RefSeq GFF3 annotation track as Expanded with labels.

  4. Save this image in PDF format.

  1. Go to the Ensembl homepage. Select Chicken from the drop-down menu in the blue box and enter 5:38111022-38265293 into the text box. Click Go.

    This genomic region is made up of one contig indicated by the dark blue coloured bar in the Contigs track.

  2. Make sure your cursor is set to the Select a region action (you can change your cursor action in the top right-hand corner of the Region in detail view). Drag a box around the ESRRB gene (note that you will need to highlight the feature itself, i.e. the block, rather than the label) and click on Jump to region.

  3. Click on Configure this page in the left-hand panel to open the configuration menu. Enter RefSeq GFF3 annotation into the search box in the top left-hand corner. To enable the track, click on the square next to the track name RefSeq GFF3 annotation and select the Expanded with labels style. Save and close the pop-up menu.

  4. Click on the Export this image icon above the image and then on the Download button to download the image in PDF format.
