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.

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.
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 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.
Following the initiation of DNA replication, the first step is the synthesis of a short RNA primer.

No, RNA polymerase does not require a primer for transcription.
it synthesizes a single RNA primer at the 5' end of the leading end.
Primase. It's usually depicted on the leading strand as square/rectangle.

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 RNA. Transcription is the process by which RNA is synthesized from DNA, while translation is the process by which proteins are synthesized from RNA.
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.
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.
