Verified step by step guidance1
Understand that RNA polymerases are enzymes responsible for transcribing DNA into RNA.
Recognize that in eukaryotic cells, there are different types of RNA polymerases, each responsible for synthesizing different types of RNA.
Identify the three main types of RNA polymerases in eukaryotic cells: RNA polymerase I, RNA polymerase II, and RNA polymerase III.
RNA polymerase I is primarily responsible for transcribing ribosomal RNA (rRNA), except for 5S rRNA.
RNA polymerase II synthesizes messenger RNA (mRNA) and some small nuclear RNAs (snRNA), while RNA polymerase III is responsible for transcribing transfer RNA (tRNA), 5S rRNA, and other small RNAs.
