DNA methylation beta values at 37,488 CpG sites for beluga whales collected in Cook Inlet, Alaska, between 1992 and 2018
A custom DNA methylation array was used to measure methylation levels at 37,488 cytosine-guanine sites (CpGs) in the beluga genome using a calibration dataset of deceased beluga whales with estimated chronological ages (n=69) using tooth growth layers. Data were generated on a bead array using Illum...
