| This spacer region coincided with the presence of an intron between the zinc fingers in the DNA sequence of the group C genes. |
| The fragments were cloned and DNA sequencing demonstrated that they actually corresponded to cDNA with proper intron splicing. |
| Each intron is removed in a separate series of reactions by a complicated piece of enzymatic machinery called a spliceosome. |
| The second insertion traps an exon of a different gene contained in an intron of the former gene. |
| The dashed line and lowercase letters represent intron sequences and the solid line and uppercase letters represent exon sequences. |
| There are also two dinucleotide microsatellites and one mononucleotide microsatellite, all in the first intron. |
