Day 166 (Xp22.2-Xp21.3): part of the DNA-copying machine


Day 166 has 39 protein-coding genes (browser view) including POLA1 (DNA polymerase alpha catalytic subunit).

POLA1 is part of one of your DNA-copying machines (DNA polymerases) that go into action when cells divide. This alpha version of the polymerase starts the work of copying DNA, but then hands this job off to other versions of polymerase, because the alpha version is good at starting to copy but then falls off DNA quickly (lacks processivity.)
