Nod factors are recognized by the Nod factor receptor (NFR) in legumes, Upon binding to Nod factors, the NFR heterodimer initiates two main separate processes mediated by SYMRK such as;

a) A signaling pathway that facilitates the infection process itself

b) Activation of the symbiosis receptor-like kinase (SYMRK)

c) Activating an extracellular domain that includes a leucine rich repeat (LRR) region and an intracellular protein kinase domain

d) The activation of a set of genes that regulate the formation of root nodules

Which of the following are the two main separate processes of NFR heterodimer?

#Unit 3. Fundamental Processes

Choose correct statements about recognition mechanism of TBP ;

A. TBP causes the minor groove to be widened to an almost flat conformation

B. It also bends the DNA by an angle of ~120o

C. The interaction between TBP and DNA involves maximum number of hydrogen bonds between the protein and the edges of the base.

D. Much of the specificity is imposed by two pairs of phenylalanine side chains that intercalate between the base pairs at either end of the recognition sequence and drive the strong bend in the DNA.
