Question

Using the GRCh38.p13 human reference genome, retrieve the reference DNA sequence for chromosome 1 from positions 1,000,000 to 1,000,100 (1-based, inclusive) on the '+' strand, and calculate: (1) gc_percent (rounded to 2 decimals), (2) length, (3) n_count (the number of Ns in the sequence), and (4) sequence_md5 (MD5 of the uppercase interval sequence). Return the results as a comma-separated string in the format: gc_percent,length,n_count,sequence_md5. For example: "31.86,10,50,v24a827t740a77764d0d8e35ba56f612"
