Use the figure to answer the following question. A space probe returns with a culture of a microorganism found on a distant planet. Analysis shows that it is a carbon-based life-form that has DNA. You grow the cells in 15N medium for several generations and then transfer them to 14N medium. Which pattern in the figure would you expect if the DNA was replicated in a conservative manner?

Cytokinin
signals to nuclear-localized response regulators by transferring the phosphate group to an
aspartate on the receiver domain of the ARR. The ARR response regulators are
encoded by multigene families, They fall into two basic classes:
I) Type-A ARRs
II)Type-B ARRs
a) The products of which are made up solely of a receiver
domain
b) Receiver domain also include an output domain containing
DNA-binding transcription activation
sites
c)
Which negatively regulate cytokinin signaling by interacting with other
proteins in a manner dependent on the phosphorylation state
d) Which are activated by phosphorylation, which enables
them to regulate the transcription of a set of target genes
e) Which are targeted by F-box proteins called KISS ME
DEADLY (KMD) proteins negatively regulates the cytokinin response
Which of the following are the correct explanation of the given ARRs types classes of response regulator?
