- Purine:AG 2 rings => bigger
- Pyrimidine:CT 1 ring
- Transition Purine:Purine or Pyrimidine:Pyrimidine ; 2/3 of the snps
- Transversion Purine:Pyrimidine or Pyrimidine:Purine ; 1/3 or the snps
- Immunity
- MIC
- Horizontal gene transfer
- Gene therapy
- Wild type typical form of an organism, strain, gene, or characteristic as it occurs in nature; most common phenotype
- Gram-negative bacteria cell walls has an outer membrane; many are pathogenic
- Q20: the number of bases in a read that have a quality value greater than 20; quality value of 20, there is a 1 in 100 chance that the base has been misidentified
