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.

Following statements are regarding thyroid hormone biosynthesis?
I. The basolateral membranes of thyrocytes facing the capillaries contain a antiporter that transports two Na+ ions and one I– ion into the cell with each cycle, against the electrochemical gradient for I–.
II. Na+/I– symporter (NIS) is capable of producing intracellular I– concentrations that are 20–40 times as great as the concentration in plasma.
III. TSH induces both NIS expression and the retention of NIS in the basolateral membrane, where it can mediate sustained iodide uptake.
