#Unit 10. Ecological Principles
  1. In each individual, the form of the behaviour is determined entirely by genes.
  2. The behaviour varies among individuals.
  3. An individual's reproductive success depends in part on how the behaviour is performed.

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?
