Question

Some exons in the human genome are quite small (less
than 75 bp long). Identification of such “microexons” is
difficult because these distances are too short to reliably
use ORF identification or codon bias to determine if
small genomic sequences are truly part of an mRNA
and a polypeptide. What techniques of “gene finding”
can be used to try to assess if a given region of 75 bp
constitutes an exon?
