What is a RefSeq?

A) A RefSeq is a single, complete, annotated version of a species' genomic DNA sequence that can be accessed for bioinformatic studies.
B) A RefSeq is a constantly updated collection of DNA sequences from all species that give the latest information for bioinformatic studies.
C) A RefSeq is a program to compare genome sequences.
D) A RefSeq is a program that identifies open reading frames.
