Hi,

 This is Vidya, Jr research Associate. I have a doubt regarding the
sequence retrieval of a gene. e.g. I want the sequence for chromosome 1:
179846800 to 179847000, when I am giving the gene name, the coordinates
given by UCSC is 179809102 to 179846941. This sequence has 59 nucleotides
less at the end when compared to my query. Please suggest me whether I
should add the nucleotides by checking promoter/upstream checkbox or
downstream checkbox? When I check on the upstream checkbox, the
nucleotides are added in the beginning of the sequence but the position
number changes at the end. why is it so?
Below I am giving the sequences retrieved;
1.Original gene sequence
>hg19_knownGene_uc001gnl.3 range=chr1:179809102-179846941 5'pad=0 3'pad=0
strand=- repeatMasking=none

2. Sequence got when I checked upstream checkbox with addition of 59
nucleotides.
>hg19_knownGene_uc001gnl.3 range=chr1:179809102-179847000 5'pad=0 3'pad=0

Please resolve the problem for which I would be grateful.
