Which enzymes catalyzes the linking together of RNA nucleotides to form RNA?

RNA polymerase. In molecular biology, RNA polymerase is an enzyme that synthesizes RNA from a DNA template. RNA polymerase opens the double-stranded DNA so that one strand of the exposed nucleotides can be employed as a pattern for the synthesis of RNA, a process called transcription.

The transcription factor and its associated transcription mediator complex must be fixed to a DNA binding site called a promoter region before RNAP can initiate the DNA unwinding at that position. RNA polymerase encourages RNA transcription and guides the nucleotides into position, enabling attachment and elongation, has intrinsic checking and replacement capabilities, and termination recognition ability.

In eukaryotes, RNAP can develop chains as long as 2.4 million nucleotides. RNA polymerase is crucial for life and is found in all living organisms.

The enzymes that catalyze the linking together of RNA nucleotides to form RNA are known as RNA polymerases. With the RNA polymerases, the phosphodiester bonds are formed and link the nucleotides together so as to form a linear chain.

Similarly, the DNA polymerase also catalyzes the DNA replication. The RNA polymerase travels stepwise alongside the DNA, and it unwinds the DNA helix ahead of the active site in order that a new region of the template strand might be exposed by polymerization for complementary base pairing.

The growing RNA chain, in this manner, would be extended by a single nucleotide at a time toward the 5’ to 3’ direction. The substrates happen to be nucleoside triphosphates (CTP, GTP, ATP, and UTP). In the case of DNA replication, there is a provision of energy that is required to drive forward the reaction by hydrolysis of high energy bonds.

The enzymes are called RNA polymerase. This is considered to be the main transcription enzyme. It will make sure that the promoter sequence can be found near the beginning of the gene. This will also make use of the DNA strands in order to create a completely new RNA molecule.

This type of enzyme will be responsible for copying the DNA sequence into the RNA sequence. This will make the process of transcription possible. Transcription will come in three stages namely initiation, elongation, and termination. RNA polymerase can be found in the nucleolus. The specialized nuclear substructure will make sure that rRNA can be properly transcribed so that they can form into ribosomes.
