RNA polymerase's main job is to transcribe mRNA from double stranded DNA. It does so by recognizing promoter region in ds DNA and binds over there. Sigma factor is a subunit of RNA polymerase that helps in locating promoter region. RNA polymerase simply synthesized complimentary base pairs from DNA template and makes mRNA. so there is no need of primer at all.
What else can I help you with?
What is the function of these short RNA segments during replication?
they form mrna molecules used in translation
What is a RNA primer removed by?
A RNA primer in DNA replication is removed by an enzyme called DNA polymerase I in prokaryotes and DNA polymerase δ in eukaryotes. These enzymes have exonuclease activity that can remove RNA primers and replace them with DNA nucleotides.
Why is it called a RNA primer?
The RNA primer is referred to a short RNA fragment into which are added deoxyribonucleotides by DNA polymerase III during DNA replication. The primer stimulates the synthesis of the new chain by participating in the initiation of polymerization of the desoxyribonucleotides. In nucleic acid chemistry, a primer can be a short, either single-stranded RNA or DNA, segment that functions as the starting point for the polymerization of nucleotides.
The process of assembling a protein form RNA is called?
The process of assembling a protein from RNA is called translation. During translation, the information encoded in the RNA is decoded by ribosomes to synthesize a specific protein according to the sequence of nucleotides in the RNA.
What does the synthesis of a new strand of DNA begin?
Following the initiation of DNA replication, the first step is the synthesis of a short RNA primer.
What is the function of these short RNA segments during replication?

Does RNA polymerase require a primer for transcription?
No, RNA polymerase does not require a primer for transcription.
What is the function of primer in PCR?
it synthesizes a single RNA primer at the 5' end of the leading end.
Which of these is responsible for catalyzing the formation of an RNA primer?
Primase. It's usually depicted on the leading strand as square/rectangle.

A RNA primer in DNA replication is removed by an enzyme called DNA polymerase I in prokaryotes and DNA polymerase δ in eukaryotes. These enzymes have exonuclease activity that can remove RNA primers and replace them with DNA nucleotides.

Why doesn't RNA polymerase require a primer for transcription?
RNA polymerase does not require a primer for transcription because it can initiate the process on its own by recognizing specific DNA sequences called promoters. This allows RNA polymerase to bind to the DNA and start synthesizing RNA without the need for a primer like DNA polymerase does during DNA replication.
Translation is to protein as transcription is to?
Translation is to protein as transcription is to RNA. Transcription is the process by which RNA is synthesized from DNA, while translation is the process by which proteins are synthesized from RNA.
Why only RNA primer provide 3-OH' end for DNA replication?
The reason you only need RNA primer at the end to make a DNA replication is because it has a free 3' OH. RNA is ribonucleic acid. RNA contains long chains of nucleotides.
What primer is needed at the origin of nucleotide addition?
A primer made of RNA is required at the origin of nucleotide addition for DNA replication. This primer provides a free 3' OH group for DNA polymerase to start adding nucleotides and serves as a starting point for DNA synthesis.
