Phytochromes  involved  in  red/far‐red  response  are  dimeric  chromoproteins contains N-terminal and C-terminal moiety have domains, which perform various functions such as;

a) Photochromobillin attach with the N-terminal GAF domain, it is an enzyme which causes isomerisation activity in the phytochromobilin

b) PAS-GAF-PHY is a photosensory domain

c) PAS domain perform the lyase activity at C-14 and C-15, which creates a double bond

d) PRD is PAS related domain which involve in import of Phy-B in the nucleus

Which of the following combinations of domain functions is incorrect?

ATM and ATR are protein kinases that become activated following specific types of DNA damage. 

A. ATM becomes activated in response to double‐strand breaks, which are detected by the MRN protein complex. 

B. ATR becomes activated by protein‐coated ssDNA that forms when replication forks become stalled or the DNA is being repaired after various types of damage.

C. ATR phosphorylates and activates the checkpoint kinase Chk2, which phosphorylates p53. D. ATM phosphorylates and activates the checkpoint kinase Chk1, which phosphorylates and inactivates the phosphatase Cdc25.
