MCQ
The transcription unit extends from:
- ATATA box to start point
- BTATA box to stop codon
- CStart point to stop codon
- D35 sequence to start point
Explanation:
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.
