Which statement about RNA polymerase is NOT true?

Which of these single strand sequences or oligoes could form a hairpin structure?

One major difference between eukaryotic transcription and prokaryotic transcription is that:

An mRNA has the stop codon 5′ UAA 3′. What tRNA anticodon will bind to it?

Which of the following is NOT necessary for RNA polymerase to recognize the promoter of a bacterial gene?

In Figure 4 the solid circles represent amino acids, the big and small ovals represent the small and large subunits of the ribosome. a, b, and c are three tRNAs after the peptide bond forms, what will happen next? Figure 4. 

Consider the random variables X with mean 5, variance 2 Y with mean -3, variance 1 Covariance(X,Y)=-0.25 What is the variance of the linear combination of 2X-0.5Y, i.e.

When two random variables are independent what will their correlation [correlation] value be? When the correlation is 0 it implies that choose [choose]
