Day 61 has only 19 protein-coding genes (browser view). Today’s highlight is one of the types of repetitive sequence that makes up over half of the genome: a simple repeat. This particular repeat is over a thousand bases long and consists mostly of As and Ts.
These simple repeats tend to crop up in the genome through a mistake in copying DNA called replication slippage.
