Under ‘‘light conditions,’’ reduced thioredoxin cleaves the disulfide bonds of CP12 and phosphoribulokinase. 

The reduction of phosphoribulokinase and CP12 separates the

components of the ternary complex releasing the active phosphoribulokinase and the active A4B4-glyceraldehyde 3-phosphate dehydrogenase.

Chemical mutagens can be divided into two groups:

those that are mutagenic to both replicating and nonreplicating DNA, such as the alkylating agents and nitrous acid; and 

those that are mutagenic only to replicating DNA, such as base analogs— purines and pyrimidines with structures similar to the normal bases in DNA.
