In what way is eukaryotic transcription more complex than prokaryotic transcription?
a. eukaryotes have three different rna polymerases, whereas porkaryotes only have one rna polymerase.
b. eukaryotic transcription initiation is much more complex than prokaryotic initiation because of the various transcription factors involved
c. upstream elements are required for efficient transcription in eukaryotic cells, but these elements are not usually necessary in prokaryotes.
d. eukaryotic mrna is made in the nucleus
e. all of the above statements outline ways that eukaryotic transcription is more complex

Nextend of semester testsubmit testreader toolsinto-samosquitoes in tropical regions can carry and transmit the malaria parasite to humans. the mosquitoes used to be killed in these regions by sprayingthem with the insecticide ddt. the mosquitoes that were earlier sensitive to ddt are now not killed by ddt and grow and multiply even in the presenceof ddt. how can you explain this phenomenon? oa.all of the mosquitoes must have undergone a mutation for ddt resistance and produced similar kind of resistant offspring, whichevolved into a ddt resistant population.b.some of the mosquitoes must have undergone a mutation for ddt resistance and produced similar kind of resistant offspring, whichwould have been selected by nature,oc.all of the mosquitoes must have slowly increased their tolerance level to ddt and ultimately would have become completely resistantto ddtresetnextnext
