What is the difference between the sugar in DNA and RNA?
In DNA, the sugar is Deoxyribose while in RNA the sugar is Ribose
In DNA, the sugar is Ribose while in RNA the sugar is Deoxyribose
In DNA, it is a 5 carbon sugar while in RNA it is only a 4 carbon sugar.
There is no difference between the sugars
Where does RNA polymerase know where to start copying down instructions in the DNA molecule?
By looking for Promotors in the code to signal to start copying
By looking for Stop Codes in the code to signal to start copying
It doesn't matter where it starts, it will find it.
mRNA signals to the RNA polymerase where to start
