Phylogenetic trees are graphical representations of the relationships among species, at which the closer two organisms are, the closer they are put together in the tree. Modern phylogenetic trees are constructed based on the anaylsis of genetic material, usually mitochondrial DNA. In this case, flowers with different phenotype and genotype were classified in a phylogenetic tree. Since flowers on peak 1 and flowers on peak 4 are grouped together it is safe to assume that the two organisms are genetically identical. I attached the missing figure.

Lana71 [14]

Answer: correct: The CAP-cAMP complex unbends the DNA loop, thereby allowing binding of RNA polymerase

Explanation:

The CAP-cAMP complex unfolds the DNA loop, allowing the binding of RNA polymerase. The catabolite activating protein, when bound with cAMP, is known to stimulate the transcription of the operon lactose genes, being necessary for the reaction RNA polymerase
