Rna splicing

A two step reaction in which introns are removed from a primary rna transcript and exons are joined together to form a mature mrna. An intron usually contains a clear signal for splicing, but in some cases a splicing signal may be masked by a regulatory protein. This results in alternative splicing. In rare cases a pre-mrna may contain several ambiguous splicing signals, resulting in a few alternatively spliced mrna.

Re: Have all human genes been identified?

... the open reading frames, so we pretty much know where most of the RNAs come from (we think - but see Jack's post). The trick is to assign function ... will be keeping folks busy for many years. Then there is alternative splicing, which can produce several different protein structures from the ...

Re: How dominance works at the DNA/RNA/protein

... can be of effect at any stage. Because of faulty promotor, the gene may not be transcribed. There may be something wrong with the mRNA (missing splicing points, wrong iniciation/polyA signal, whatever) leading to significantly reduced half-life of the mRNA. There may be STOP codon in middle ...

Idea to determine order of assembly of spliceosome

... assemble to a spliceosome. My initial thought was to use in vitro splicing assay with a couple of extra steps. 1. Ligate a traget gene to a vector with some kind of bacteriophage RNA-pol promotor 2. In vitro transcription with radioactive nucleotides 3. Extraction ...
