Question restatement: The nucleotide sequence on a DNA molecule that is involved in the initiation of transcription is called the
Options:
- promoter.
- anticodon.
- codon.
- intron.
Now, analyze each option:
Option 1: promoter. This term specifically refers to a DNA sequence located upstream of a gene where RNA polymerase binds to initiate transcription. It acts as a regulatory region that signals the start of transcription, making it the correct concept for initiation.
Option 2: anticodon. An anticodon is a sequence of three nucleotides on a tRNA molecule that pairs with the complementary codon on mRNA during translation. It is not part of DNA and not involved in transcription initiation, so this is incorrect.
Option 3: codon. A codon is a sequence of three nucleotides on mRNA that encodes a specific amino acid during translation. While essential to gene expression, codons are part of RNA, not the DNA initiation region, thus this option does not answer transcription initiation on DNA.
Option 4: intron. An intron is a non-coding segment within a gene that is transcribed but removed during RNA processing before translation. Introns are not initiation signals for transcription and therefore do not fit the description in the question.
In summary, option 1 (promoter) uniquely matches the description of a DNA sequence that initiates transcription, while the other options refer to components of transcription or translation that do not fulfill the initiation role on DNA.
