Which of the following is a chemical or structural characteristic of RNA? The RNA sugar is ribose, which has an OH group on the 2' carbon. O RNA is usually a single-stranded molecule. The bases in RNA include uracil instead of thymine. RNA molecules are generally shorter in length compared DNA macromolecules. All of the above are either a chemical or structural characteristic of RNA. Which of these sequences could form a hairpin? 5' GGGGTTTTCCCC 3' 5' AAAAAAAAAAAA 3' 5'...

Which of the following statements about DNA replication is FALSE? Primase synthesizes the primers. DNA polymerase is required to add new nucleotides to the growing ends of the DNA strands. DNA ligase joins the small DNA fragments of the lagging strand. Only one strand of the parent DNA serves as a template for a newly synthesized complementary strand.
Which of the following occurs ONLY in eukaryotic cells and NOT in prokaryotic cells? RNA polymerase...
Which of the following occurs ONLY in eukaryotic cells and NOT in prokaryotic cells? RNA polymerase binds to the DNA template at the promotor sequence of the gene RNA polymerase is capable both of unwinding and separating the DNA helix - hence displaying part of the DNA template for transcription - and of catalyzing the formation of phosphodiester bonds. RNA polymerase pairs up Uracil (U) in the elongating RNA strand with Adenine (A) in the DNA template RNA polymerase pairs...

RNA polymerase activity that base-pairs and polymerizes nucleotides to make mRNA. b. Helicase activity that unwinds the double-stranded DNA molecule for transcription c. Specific recognition of -35 box and -10 box sites in the promoter region. d. General binding that helps RNA polymerase loosely adhere to DNA, before Transcription begins. Oe. Trick Question.
