Understand that transcription is a process in molecular biology where the information in a DNA sequence is copied into a complementary RNA sequence.
Identify the key components involved in transcription: DNA template, RNA polymerase enzyme, and ribonucleotides (RNA building blocks).
Recognize that transcription occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells.
During transcription, RNA polymerase binds to a specific region on the DNA called the promoter, initiating the synthesis of RNA.
The RNA polymerase moves along the DNA template strand, adding complementary RNA nucleotides to build a single-stranded RNA molecule, which is a copy of the gene's coding sequence.
