Elesar Annotation for Genes 20 and 21
1/30/19
Rational:
To continue annotation and learning how annotate gene 1. Annotated what has been learned thus far for gene 20 and 21.
Procedure:
- Opend the auto-annotated Elesar
- Calculated the gap/overlap between the upstream gene from gene 1
- Determined whether the gene was the longest ORF
- Selected the gene and pressed the RBS button to get the Z-score, final score and determine whether the current ORF is the best according to the RBS
- For gene 20 and 21 found the SSC
- Looked at GeneMark to determine if the gene covers the coding potential
- Found the longest ORF
- BLASTed the proteins for gene 20 and 21
- Wrote down the name of the phage name that aligned with the gene and the gene number
- Wrote what database the alignment was found in
- Determined what basepair the query and the subject started matching at
- Found the e-value for the match (shows the likelihood the alignment was random)
Observations:
- Gene 1 is the first gene so in gap 1st gene was written
- The gene was pushed back to an earlier start making it the longest ORF
- Entered the scoring and spacing matrix under the RBS (Kibler7 and Karlin Medium)
- The Z-score was not the best for the current start, but it was determined that it was still the best
- Both alignments for gene 20 and 21 were from NBCI
Conclusion:
The annotations up to RBS were finished for gene 1. Genes 20 and 21 were then also annotated up to the same point. Next lab I will finish learning how to do the rest of the annotations steps and practice on gene 20 and 21.
