Sometimes a single-stranded molecule of RNA is able to fold back on itself because the nucleotide sequence on one part of the RNA is complementary to another part. This sequence motif directly results in a: Group of answer choices transcription factor binding site RNA polymerase hairpin-shaped structure membrane protein A large number of new mutations occuring in an animal genome every generation would be acceptable if: Group of answer choices there were good DNA repair mechanisms most of the genome...

Which statement among A-D is false regarding non-retrovirus RNA viruses? A. they possess RNA-dependent RNA polymerase B. the genome of single stranded (+) RNA virus like West Nile virus, can serve directly as mRNA C. during the multiplication process inside a host cell, a single stranded (-) RNA virus must go through a (+) RNA stage before forming progeny phage D. such viruses can produce a provirus form in the host E. None of A-D is false, they are all...
