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. So basically the reason this is called an antisense because this has a complementary nucleotide sequence to this strand here. So this three to five strand is known as the antisense strand and our RNA polymerase uses the antisense strand to basically direct the synthesis of our RNA molecule and the other strand is known as the sens strand or the coating strand. So once again notice that just like DNA polymerase RNA polymerase can only read the DNA strand in the three to five direction and it can synthesize the RNA strand shown in green in the five to three direction.
