For example GGTCAATCT or GGCCAATCT are CAAT box sequences.
This is a sequence of nucleotides found in a conserved region of 5' DNA end located "upstream" (direction) of the start points of eukaryotic transcription units. Transcription factors binds to it and it is believed to determine the efficiency of transcription. These boxes are found in many promoters at -75 bp.
Answer:
<u><em>The correct option is D) Keystone</em></u>
Explanation:
In environmental studies, a keystone animal can be described as one of the most vital element or animal or a particular community. In a food chain, the keystone animal is of particular importance and if it is removed then the entire food chain will be affected by it.
