Transcription and translation An enzyme called RNA polymerase (primase) begins the replication process by adding RNA nucleotides to each template nucleoside. A molecule of DNA polymerase III binds to each of the separated strands. This enzyme adds nucleotide bases to their complementary bases on the template strand after the RNA primer sequence and proofreads to prevent improper nucleotides from being joined tothe template.

RNA Synthesis of RNA is usually catalyzed by an enzyme— RNA polymerase —using DNA as a template, a process known as transcription. Initiation of transcription begins with the binding of the enzyme to a promoter sequence in the DNA (usually found upstream of a gene).his process uses transfer RNA (tRNA) molecules to deliver amino acids to the ribosome, where ribosomal RNA (rRNA) then links amino acids together to form proteins.

- This is true not only for the synthesis of RNA during transcription, but also for the synthesis of DNA during replication. The enzymes, called polymerases, are used to catalyze the synthesis of nucleic acid strands. RNA strands are synthesized by RNA polymerases. DNA strands are synthesized by DNA polymerases.

- Mechanism. For each DNA base, RNA polymerase adds to its RNA molecule a complementary RNA base. As is usually the case in genetics, the DNA sequence is critical. This sequence determines the type of RNA that's being synthesized, as well as which of the existing RNA polymerases (I, II or III) will do it.ranscription, the first step in transforming DNA into proteins, is mediated by an enzyme named RNA polymerase. It consists of reading a sequence of DNA and transforming it, base by base, into a complementary sequence of RNA.

Compare and contrast the functioning of DNA polymerase and RNA polymerase? DNA polymerase synthesizes DNA, but needs a primer in order to initiate synthesis. DNA = Deoxyribonucleic Acid (H). RNA = Ribonucleic Nucleic Acid (OH). DNA is double stranded. RNA is single stranded. DNA uses Thymine as a base. RNA uses Uracil as a base.Now, come up with the similarities yourself.here are a lot of differences between the two proteins. RNA polymerase does not require a primer whereas DNA polymerase does. DNA polymerase goes until the job is finished, whereas RNA polymerase goes until it reaches a stop sequence.

Figure 3: RNA polymerase at work. RNA polymerase (green) synthesizes a strand of RNA that is complementary to the DNA template strand below it.ithin the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.

Ribosomes, Transcription, and Translation The helicase unzips the double-stranded DNA for replication, making a forked structure. The primase generates short strands of RNA that bind to the single-stranded DNA to initiate DNA synthesis by the DNA polymerase. This enzyme can work only in the 5' to 3' direction, so it replicates the leading strand continuously.uring transcription, enzymes called RNA polymerases build RNA molecules that are complementary to a portion of one strand of the DNA double helix (Figure 3).
