If the 5’ splice site sequence changed from 5’- GUAAGU-3’ to 5’-GUAUGU-3’, predict the effect of the sequence change on U1 binding and U6 snRNP binding in an in vitro protein– RNA binding assay.

#Unit 3. Fundamental Processes

  1. The mutation will not change binding of U1 and on other hand this will likely enhance binding of the U6 snRNP with the 5’ splice site

  2. The mutation will likely cause an increase in binding of U1 and on other hand this will not change binding of the U6 snRNP with the 5’ splice site

  3. The mutation will likely cause a decrease in binding of U1 and on other hand this will likely enhance binding of the U6 snRNP with the 5’ splice site

  4. The mutation will likely cause a decrease in binding of U1 and on other hand this will not change binding of the U6 snRNP with the 5’ splice site

Some given  statements about biosynthesis of Abscisic acid ;
a) ABA is synthesized in almost all cells that contain chloroplasts or amyloplasts
b) ABA is a 15-carbon terpenoid, or sesquiterpenoid, which is synthesized in plants by an indirect pathway via 40-carbon carotenoid intermediates
c) Cleavage of the carotenoid by the enzyme NCED (9-cis-epoxycarotenoid dioxygenase) is a rate-limiting
d) Oxidation by ABA-8′-hydroxylases lead to ABA inactivation, ABA can also be inactivated by conjugation, but this is irreversible. Both types of inactivation are also tightly regulated.
