So it synthesizes our RNA beginning at the five end and ending at the three end as shown in a following diagram. So this green strand is in fact our RNA strand. Now the DNA strand that is used to actually synthesize the RNA strand is known as the template strand or more commonly the antisense strand. Now the other DNA strand is called the sense strand or the coating strand. And basically the nucleotides found on this trend are almost exactly the same as the nucleotides found on the RNA strand. The only difference is the thymines are replaced with uracil on the RNA because remember in RNA the thymines are replaced by the uracil.
