Example sentences for: branch-point

How can you use “branch-point” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • This appears inconsistent with the revertant sequences here, which show selection for a Watson-Crick base pair at the position 3' but not 5' to the branch-point nucleotide.

  • Hence, the branch-point nucleotide is absolutely required for mobility.

  • More recent support for this upstream weak or non pairing with simultaneous downstream pairing, was observed in all lariat forming group II introns in barley chloroplasts [ 23 ] . Here 13/16 introns lacked Watson-Crick pairing above the branch-point A and G:C was the downstream base pair whenever there was an upstream A:C, A:G or G:G.

  • From previous reports it was noted that if the branch-point nucleotide was changed to a C, branching was reduced [ 20 22 ] . In this case it is likely that the sensitivity of our assay permits the detection of homing products.

  • In aI5γ, G and U at the branch-point were found to allow for some branching to occur [ 22 ] . Also, it was observed that even if the branch-point residue was paired, it did not have a large effect on splicing efficiency and no effect on the choice of the branch site [ 20 ] .
