During splicing, an unusual type of base pairing occurs. What is it and what does it do?

#Unit 3. Fundamental Processes

  1. G to C base pairing that helps to draw the 3' end of exon 1 close to the 5' end of exon 2

  2. G to G base pairing that helps to draw the 3' end of exon 1 close to the 5' end of exon 2

  3. G to A base pairing that helps to draw the branch point close to the beginning of the intron

  4. G to G base pairing that helps to draw the branch point close to the beginning of exon 2
