I've been conducting research on a disease and wanted to include some
genetic data in my work. I did a Nucleotide search on PubMed for my
disease and came up with the sequence below. Where is the start codon
in this seuqnce? How do I know how many genes are represented in this
sequence? When searching for nucleotide sequences with multiple
results, how do i choose the
best sequences (most accurate)?
