Question

which of the following events occurs during transcription?
the message in mrna is translated into a protein.
a molecule of rna is formed based on the sequence of nucleotides in dna.
a cap is added to the rna molecule.
mrna binds to a ribosome in the cytoplasm.
those segments of the rna strand that do not actually code for the protein are removed.

Explanation:

• Option 1: Translating mRNA to protein is translation, not transcription.
• Option 2: Transcription is the process where DNA's nucleotide sequence is used to synthesize an RNA molecule (like mRNA, tRNA, rRNA), so this matches transcription.
• Option 3: Adding a cap to RNA is part of RNA processing (post - transcription), not transcription itself.
• Option 4: mRNA binding to a ribosome is part of translation, not transcription.
• Option 5: Removing non - coding RNA segments (splicing) is post - transcriptional processing, not transcription.

Answer:

B. A molecule of RNA is formed based on the sequence of nucleotides in DNA.
