Verified step by step guidance

Step 1: Begin by understanding the process of transcription. Transcription is the synthesis of RNA from a DNA template, where the enzyme RNA polymerase plays a key role in catalyzing the formation of RNA strands complementary to the DNA sequence.
Step 2: Recognize the types of RNA produced during transcription. These include messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), all of which are essential for various cellular functions.
Step 3: Note that transcription does not involve the translation of mRNA into a polypeptide. Translation is a separate process that occurs after transcription, where ribosomes and tRNA decode the mRNA sequence to synthesize proteins.
Step 4: Understand the role of RNA polymerase in transcription. RNA polymerase binds to the DNA template and facilitates the addition of nucleotides to form the RNA strand.
Step 5: Identify the correct answer by eliminating options that pertain to transcription and focusing on the one that describes translation, which is not part of transcription.
