Table 7 Comparison of protein coding potential for Alu-derived exons versus other TE-derived exons. Average protein coding potentials are compared between the specific pairs of groups indicated using the Student's t-test. Comparisons were done using two GeneMark models: pre-trained and custom-trained (see Methods).
