|
|
Term
Which is not a similarity between transcription and replication?
A. Both are highly regulated by the cell.
B. Both have same matching nucleotides rules.
C. Occurs in the nucleus of eukaryotic cells.
D. Catalyzed by large, complex enzymes.
E. Involve unwinding of the DNA. |
|
Definition
B. because replication follows the rules of A pairs with T and C pairs with G while transcription follows the rules of A pairs with U and C pairs with G. (The key word in the question above is the same)
If you put letter choice A, go see for yourself on pg. 242 of the textbook.
If not, you can see me at 3:00 if you want to argue with me more. (Jason knows what I am talking about) |
