Question

The transcription unit extends from

• A. TATA box to start point
• B. TATA box to stop codon
• C. Start point to stop codon
• D. 35 sequence to start point

Answer 1

The correct option is B TATA box to stop codon

• Transcription in genetics refers to the process of recording or copying a DNA's message onto a related RNA in its language.
• The transcription unit is made up of a promoter, structural gene, and a terminator.
• The promoter initiates and controls the process, while the terminator indicates when and where to stop transcribing.
• Each gene has its own promoter and in eukaryotes, the promoter is always the same and is known as the TATA box as the sequence of bases is TATAAA.
• The transcription unit extends from the TATA box to the stop codon or the terminator.
  

So, the correct answer is option B.
