    Gene Regulation and Genetic Expression in Infants

    Understanding the nuances of gene regulation and genetic expression in infants is pivotal for comprehending how early life stages affect overall health and development. These processes dictate the activation and silencing of genes, influencing the physiological and metabolic pathways of newborns.

    Understanding Gene Regulation in Neonates

    Gene regulation in neonates involves controlling the transcriptional activation of genes, ensuring proteins are synthesized at the right time and in the right amounts.

    Key mechanisms include:
