Question

match each term to its description.
terminator promoter transcription bubble
template strand rna polymerase
the strand of dna to which complementary rna nucleotides are added, creating mrna
a section of a gene unzipped by rna polymerase
an enzyme that joins rna nucleotides to create an mrna molecule from a dna template strand
a specific dna sequence of nucleotides that signals the end of a gene
a binding site for rna polymerase that determines where transcription begins

Explanation:

Each term is matched based on core definitions of eukaryotic/ prokaryotic transcription molecular biology concepts:

1. The DNA strand used as a guide for mRNA synthesis is the template strand.
2. The unzipped region of DNA during transcription is the transcription bubble.
3. The enzyme catalyzing mRNA building from DNA is RNA polymerase.
4. The DNA sequence signaling transcription stop is the terminator.
5. The DNA sequence where transcription initiates is the promoter.

Answer:

• The strand of DNA to which complementary RNA nucleotides are added, creating mRNA: template strand
• A section of a gene unzipped by RNA polymerase: transcription bubble
• An enzyme that joins RNA nucleotides to create an mRNA molecule from a DNA template strand: RNA polymerase
• A specific DNA sequence of nucleotides that signals the end of a gene: terminator
• A binding site for RNA polymerase that determines where transcription begins: promoter
