An analysis of the primary transcript of miR-184 (pri-mir-184) in several mouse tissues revealed specific expression in the brain and testis.

The early primary transcripts continue to be produced after DNA replication begins.

The additional primary transcript produced late in infection is large and comes from 5/6 of the 32kb adenovirus genome.

In addition, the primary transcript contained multiple polyadenylation sites, giving different 3' ends for the processed mRNAs.

The primary transcript of this gene contains an intron with two possible acceptor sites.

Given the primary transcript begins at base 7539277, the promoter overlaps with it by 304 bases.

During capping, a 7-methylguanosine residue is attached to the 5'-terminal end of the primary transcripts.

The "ERα" primary transcript gives rise to several alternatively spliced variants of unknown function.

The primary transcript of this gene is 1,919 base pairs long.

They have the primary transcript and the mature transcript marked up.
