Question 16 1 pts Which is true of RNA polymerases in both prokaryotic and eukaryotic organisms? They have the same number of cofactors in prokaryotes and eukaryotes. They are composed of an analogous a 2ßß'w core. They make copies of RNA from either DNA or RNA templates. There is a single enzyme type per organism.

ect Question 8 0/2 pts Which of the following statements about RNA polymerase is NOT true? RNA polymerase finishes transcription as soon as it reaches the terminator. RNA polymerase adds a ribonucleotide to the 3' end of a growing RNA molecule. During transcription of a gene, RNA polymerase reads only one strand of DNA. RNA polymerase binds to a promoter to initiate transcription. - U 000 20 O 3 $ 4 % 5 & 7 6. 8

QUESTION 4 Which of the following provides the free 3'-OH group for DNA polymerase to fill in the ends of telomere DNA? O A. The end of the previous Okazaki fragment. O 0 The RNA primers laid down by primase. o O C. The RNA bound to telomerase. OD. The ends are filled in by RNA polymerase which does not require a free 3'-OH group.

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...
