UCSC Get Sequence

Get DNA sequence from the UCSC Genome Browser for a specified genomic region. Returns the nucleotide sequence for a given chromosome, start, and end position in a genome assembly. Useful for primer design, sequence analysis, and regulatory element inspection. Example: hg38, chr17, start=7668421, end=7668521 returns 100bp of TP53 sequence.
