Name the site where the upstream sequences located
before start point
after start point
right border of DNA
In the middle of DNA
As we have already studied in Introduction to Transcription & Transcription Unit -
Start point is the first base pair from which transcription starts. Upstream sequences are located prior to the start point known as +1 or initiation site while sequences after the start point are called downstream of it. Hence, the correct option is (a).
