Examining the length of 5′ and 3′ UTRs between GENCODE 3c and 7. (A) The length of 5′ UTR sequence (in 50-bp bins) for each protein-coding transcript. 5′ UTR annotation from GENCODE 3c (red) and 7 (blue). (*) A cutoff was made at 949 bases; longer 5′ UTRs do exist. (B) The length of 3′ UTR sequence (in 250-bp bins) for each protein-coding transcript. 3′ UTR annotation from GENCODE 3c (red) and 7 (blue).
