Hi! I have a question about search in NCBI, and I wasn't able to find it on NCBI or using google search. I have some Ilumina reads from Drosophila Melanogaster SRR10011001 (for practice I am a beginner in Bioinformatics), and I have overrepresented sequences, mainly rRNA which I need to filter out. Now I went to NCBI and typed the Drosophila melanogaster genome, selected Nucleotide and on the left chose only rRNA sequences, the result was 110. But when I typed in only Drosophila melanogaster, the result is 165 sequences of rRNA. Can someone explain why? When I include genome, does it mean rRNA only from chromosomes and not from mtDNA? Thanks in advance!
