Louie (season 1) began airing in the 2010s.
The U7 small nuclear RNA -LRB- U7 snRNA -RRB- is an RNA molecule and a component of the small nuclear ribonucleoprotein complex -LRB- U7 snRNP -RRB- .. snRNA. Small nuclear RNA. The U7 snRNA is required for histone pre-mRNA processing .. snRNA. Small nuclear RNA. histone. Histone 3' UTR stem-loop. The 5 ' end of the U7 snRNA binds the HDE -LRB- Histone Downstream Element -RRB- , a conserved purine-rich region , located 15 nucleotides downstream the histone mRNA cleavage site .. snRNA. Small nuclear RNA. histone. Histone 3' UTR stem-loop. The binding of the HDE region by the U7 snRNA , through complementary base-pairing , is an important step for the future recruitment of cleavage factors during histone pre-mRNA processing .. snRNA. Small nuclear RNA. histone. Histone 3' UTR stem-loop
