Document Summary
Lecture 18 : overview of transcription iii - rna splicing. Rna splicing introduction - exons and introns splicing is required to remove introns and bring exons (encoding gene) together. Exons actual coding sequences that are interrupted by introns depending on the type of cell, these exons can be removed as well ( exons can be modular ) called. The mechanisms of rna splicing ( only occurs in the nucleus - as with all forms of mrna. The role of these small nuclear rnas the conserved sequences that represent the start and end point of splicing share complementary bases with these small nuclear rnas. How exactly to these small nuclear rnas and their associated proteins contribute to. In the first splicing reaction, the 5" end of the intron is attached to the conserved portion a ( ie the branch point ). In the second splicing reaction, the intron loop is cleaved off and the.
