Question

transcription occurs when ________ multiple choice a messenger rna molecule is synthesized from dna in the nucleus a transfer rna molecule is synthesized from dna in the nucleus a ribosomal rna molecule is synthesized from dna in the nucleus the blueprint of the rna molecule is used to bind amino acids together to form proteins enzymes are bound to their substrates to produce products

Explanation:

Transcription in biology is the process where a messenger RNA (mRNA) molecule is synthesized from a DNA template in the nucleus. This is the key - defining event of transcription. Other options describe different processes related to RNA synthesis or protein formation.
