[{'content': 'All are true regarding satellite DNA except : \nSelect and explain. \nA. Repeated DNA sequence in tandem, B. Clustered around centromere, C. Clustered around telomeres, D. Transcriptionally active', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Satellite DNA Result of repeat length polymorphism i.e tandem repeats of a paicular length of DNA occurs. These lengths are variable in different populations. Present around centromeric and telomeric regions DNA present around these regions is transcriptionally inactive. These repeats are of two types : STR VNTR Sho tandem repeats also known as microsatellite Variable number of tandem repeats. Length is of 2-6 base pairs (sho) Length is of 15-70 bp (variable number) <img style="max-width: 100%" src=" onclick="zoomImage(\' onclick="zoomImage(\' /> <img style="max-width: 100%" src=" onclick="zoomImage(\' onclick="zoomImage(\' />', 'role': 'assistant'}]
