So as we mentioned earlier, the process of transcription is pretty simple and that's because both RNA and DNA molecules are polymers of the same exact units of the same exact molecule known as the nucleotide. The only difference between the nucleotides of RNA and DNA molecules is that in DNA the sugar is the deoxyribose and in RNA the sugar is the ribose and in RNA the thymine are replaced with the uracil nitrogenous bases. So let's take a look at the following diagram. So let's suppose we have the following DNA molecule that we want to use as the template for transcription. And this DNA molecule is commonly known as the antisense strand or the antisense strand. So basically the antisense strand consists of our adenine cytosine adenine and thymine nucleotides.
