Solution
The DNA sequence where RNA polymerase attaches and initiates transcription is known as the promoter. Specifically, the promoter is a region of DNA that facilitates the binding of RNA polymerase and the initiation of transcription of a particular gene.
Here’s a brief breakdown of the other terms for clarity:
-
TATA box: This is a specific type of promoter sequence found in many eukaryotic genes, characterized by a repeating sequence of thymine (T) and adenine (A). It is part of the promoter region but not the entire promoter itself.
-
Exon: These are sequences within a gene that code for proteins. They are transcribed into mRNA but are not where transcription starts.
-
Intron: These are non-coding sequences within a gene that are removed during mRNA processing. They do not play a role in the initiation of transcription.
-
Codon: This refers to a sequence of three nucleotides on the mRNA that corresponds to a specific amino acid, but does not pertain to the initiation of transcription.
-
Anticodon: This is a three-nucleotide sequence on transfer RNA (tRNA), complementary to the mRNA codon, playing a role in translation rather than transcription.
Thus, in the context of your question, the term you're looking for is promoter.
