A. SeqA binds to hemimethylated DNA and is required for delaying rereplication.

B. As the origins are hemimethylated they bind to the cell membrane and may be unavailable to methylases.

C. The dat locus contains DnaA-binding sites that titrate availability of DnaA protein.

D. Hda protein is recruited to the replication origin to convert DnaA-ATP to DnaA-ADP.

Under temperate conditions, which one of the two major factors that are involved with light-dependent stomatal opening are,

#Question id: 10472

#Unit 6. System Physiology – Plant

In greenhouse grown leaves of broad bean stomatal movements closely correlate with incident solar radiation at the leaf surface and stomatal aperture  opening and closing as light levels reaching the leaf surface given in graph

A. Mid of the day stomatal aperture has a largest diameter, water loss and transpiration rate will be highest at the  same time

B. In mid of the day incident light is highest in terms of PPFD and can also say CO2 diffusion will be highest

C. The stomatal aperture has a largest diameter resulting closing of stomatal pore, water loss and transpiration rate will be lowest due to closing of stomata

D. In mid of the day incident light is highest in terms of PPFD resulting CO2 will not diffuse

which of the following combination from the given graph will be CORRECT?
