Those interested in health care might pursue CPR/First Aid certification or CNA training.

In a paper published in Nature Communications, Husbands and the team focused on two near-identical paralogs, PHB and CNA, to uncover the mechanism behind this divergence.

The researchers initially explored the functional divergence between the CNA and PHB by performing qPCR, a quantitative technique used to measure the abundance of RNA molecules and, by extension, gene-expression levels.

Initially, they focused on examining two genomic targets they expected CNA and PHB to regulate based on the team's previous research and assumptions about TFs based on other literature.

To address this paradox, they turned to ChIP-seq to systematically map all the binding sites of CNA and PHB across the genome, thus allowing the researchers to see the broader landscape of where TFs were binding.
