  1. A functional gene is a sequence that does not contain nonsense or frame shift mutation or long deletions and has initiation and stop codons at the proper positions. All the large yellow croaker OR genes are inferred from cDNA amplified from mRNA in the olfactory epithelium. Therefore, they are considered as functional genes whether full-length or partial cDNA.
