A recent study reported a high degree of variation in RNA levels in rat hippocampus taken from different animals.

They found that RNA levels for per and per also display clear rhythmicity.

It functions there to control the transcription of the ribosomal RNA levels.

Due to post-transcriptional regulation, transcription rates and total RNA levels differ significantly.

For example, Pop1p is involved in the control of the RNA levels of the cyclin Cig2p [ 33 ] .

Effect of differentiation on ATF1 protein and RNA levels.

Other factors associated with favorable response to anti-HCV treatment in children include lower pretreatment HCV RNA levels, white race, and possibly younger age (657).

Post-transcriptional regulation is the control of gene expression at the RNA level, therefore between the transcription and the translation of the gene.

Relative RNA levels and the fold induction of transcripts in the presence of DOX were estimated as follows.

Some genes may be expressed at similar RNA levels but protein levels are controlled post-transcriptionally.
