The sequence of σ54 is distinctly different from that of all the σ70-like factors, some characteristics about σ54 is given below;
a) The σ54-RNA polymerase binds to the glnA promoter and immediately melt the DNA strands and initiate transcription
b) σ54-polymerase does not require ATP hydrolysis to separate the strands at a start site only require activator such as NtrC
c) σ54-RNA polymerase initiate transcription of glnA promoter only when it is activated by NtrC
d) ATP hydrolysis is required for activation of bound σ54-RNA polymerase by phosphorylated NtrC

Use the following figure and description to answer the question.
Humans, chimpanzees, gorillas, and orangutans are members of a clade called the great apes, which shared a common ancestor about 15 million years ago. Gibbons and siamangs comprise a clade called the lesser apes. Tree-branch lengths indicate elapsed time. Assuming chimps and gorillas are humans' closest relatives, removing humans from the great ape clade and placing them in a different clade has the effect of making the phylogenetic tree of the great apes ________.
