Day 178 has 20 protein-coding genes (browser view) – relatively gene-poor.
So, today is a good day to point out another transposable element – this one called Tigger. Like L1 elements (Day 174 (Xq21.2-Xq21.33): L1, a LINE element that loves the X chromosome), Tigger elements are found throughout the genome, but are DNA transposons – they didn’t jump around via a RNA retrotransposition step, but just through cutting and pasting.
Tigger was discovered in 1996 and named due to its similarity to the pogo element found in fly.
