Question

Classify each characteristic of transcription according to whether it is found in prokaryotes only, eukaryotes only, both, or neither.
a. Translation of the mRNA begins before transcription is finished.
b. The promoters contain 2 common 6-base sequences, which are located 35 nt and 10 nt upstream from the start site-
c. RNA polymerase unwinds and separates the 2 strands of the entire transcription unit before transcription begins.
d. After the mRNA molecules are transcribed, they are modified.
e. Transcription factors must bind to the promoter before RNA polymerase Il binds to DNA.
f. Within the transcription bubble, RNA nucleotides match up with complementary bases on the template DNA strand.
g. Only one type of RNA polymerase is used for transcription.
h. Four different RNA polymerases are used for transcription.
i. New RNA nucleotides are added to the 3' end of the growing RNA transcript.
j. A number of transcription factors interact with RNA polymerase Il to form an initiation complex at the promoter.
