The CRISPR system consists of a proteinplugin-autotooltip__default plugin-autotooltip_bigProtein: a molecule that is formed by the translation of messenger RNAs (mRNAs). Functions that proteins provide are what usually give organisms their phenotypes. typically called Cas9 and two non-coding RNAsplugin-autotooltip__default plugin-autotooltip_bigRNA sequencing (RNAseq): an experimental technique that sequences all the RNAs in a sample. It is based off of converting RNAs into cDNAs with reverse transcriptase, followed by Illumina sequencing. called gRNA and tracrRNA.
