In Ensembl when I use this link to return the sequence on the sense strand of X chromosome between 200000 and 200200 I get the following output:
>X dna:chromosome chromosome:GRCh37:X:200000:200200:1 CCAAACCCCAGGCAGGAGACCAGCCCGTGTTATACGGTGCCTGGAGGAGGCGTGACTCAT TTGCATAGCGCTGAGGGGATTGGTCTGACCAGGCCTGTCATTCACGTAGCCCGCGAAAAA CCTGGCCCGCCCACCCCAGTTCCGTAATATGCAAATGTAGGGCGCCATGATGTTCCACAC GCCTGAGGGTAGTGGGGGCGG
This contains 201 nucleotides, but from my query I was expecting 200. Where has this extra nucleotide come from? Which position is it at? Is my query wrong?
