Article Discussion

"The Burmese Pythod Genome Reveals the Molecular Basis for Extreme Adaptation in Snakes" (2013)

  • Researchers clustered genes with similar trends in differential gene expression together.
  • STEM is a source of gene identifiers and clusters.
  • Volcano plots showed significant difference for no change in gene expression levels.

Questions to Consider:

  • What are the names of the genes the researchers clustered?
    • Investigate ncbi gene bank
  • What started the cascade?
    • If known transcription factors activate genes in the cascade, maybe we can find them early on.
  • If a few genes don't change, is that biologically significant?

Classwork

  • A quality score above 40 is good.
  • Sequence codes match the reagents provided in class document.
  • All reads are 76bp.
  • Very few "N's." A "N" indicates that RNAseq was unable to pick a base.
  • Intestine has smooth GC curve line.
  • The class was unable to determine what exactly "Sequence Duplication Levels" showed us.
  • Overall, our data is of good quality.


Moving forward, we need to:

  • Trim off the first 4 bases.
  • Discard reads with a score less than 15.
  • Name all the reads.
  • Sort all the reads.
  • Exhaust publicly avaible data sets.
