Which of the following statements are correct regarding Crassulacean Acid Metabolism (CAM) plants?

A. They possess "Scotoactive" stomata which open during the night and close during the day.

B. The primary carboxylation enzyme during the night is RuBisCO.

C. Malic acid is stored in the vacuole during the night, leading to acidification of the cell.

D. During the day, malate is decarboxylated to release CO2 for the Calvin Cycle.

Which of the following components must a yeast-bacterial shuttle vector possess to be functional in both hosts?

#Question id: 40425

#Applied Microbiology

Given below are two statements:

Statement I: A shuttle vector is designed to allow the cloning of a gene in E. coli and its subsequent expression in a eukaryotic cell.

Statement II: pBR322 is a classic example of a shuttle vector because it can replicate in both animals and bacteria.

In the light of the above statements, choose the correct answer from the options given below:

#Question id: 40426

#Applied Microbiology

Assertion (A): Shuttle vectors are naturally occurring plasmids found in Agrobacterium tumefaciens.

Reason (R): They contain two origins of replication, enabling them to replicate in two different host organisms
