New Clock Can Measure Biological Age Precisely by Anjanee Sharma on March 4, 2021 at 3:43 PM The BiT age (binarized transcriptomic aging clock) was developed by David Meyer and Professor Dr. Björn Schumacher. Biological age differs substantially for everyone. Aging clocks like Horvath's epigenetic clock have been based on the pattern of methylations until now. These patterns are small chemical groups that attach to DNA and change with age. The BiT age clock takes the set of genes read from DNA to make proteins for the cell into account. Earlier the transcriptome was considered too complex to indicate age as sometimes genes transcribe a large amount of mRNA and sometimes less. So it was impossible to develop precise aging clocks based on gene activity.
