Guide RNA (gRNA)

There are ~100 different known guide RNAs (aka gRNAs). There is one guide RNA per […]


Just as transcription initiation and capping are coupled, transcription termination and the 3’ cleavage and […]

RNA processing

Eukaryotes encode long precursor RNA transcripts, which are spliced, polyadenylated and capped to produce a […]

RNA splicing

Most metazoan genes have multiple exons that must be carefully excised (from the pre-mRNA) and […]

Self-Splicing Introns

Some mitochondrial, protist and archaeal genes have autocatalytic self-splicing introns (as opposed to nuclear spliceosome-dependent […]


The spliceosome is a hugely massive complex that catalyzes excision of introns and ligation of […]


Splice sites (exon-intron junctions) are located by comparing genomic DNA with the cDNA prepared from […]
