github.com - CSBB is a command line based bioinformatics suite to analyze biological data acquired through varied avenues of biological experiments. CSBB is implemented in Perl, while it also leverages the use of R and python in background for specific modules....

These are just a scant few of the common questions asked by bioinformatics students as they ready themselves for the next exam sitting

Cas9 restricts DNA at specific Protospacer Adjacent Motifs (PAMs), which is species-dependent (for example, 5′ NGG 3′ for Streptococcus pyogenes Cas9).
