Final answer:
Yes, the findings on DNA methylation in rats can extend to humans. Epigenetic changes, such as DNA methylation, can affect gene expression and have been observed in both animal models and humans.
Step-by-step explanation:
Yes, the findings on DNA methylation in rats can extend to humans. While the studies mentioned were conducted on animal models, these findings can potentially be used to generate novel hypotheses about humans. Epigenetic changes, such as DNA methylation, can affect gene expression and have been observed in both animal models and humans. For example, studies have shown that diet, maternal behavior, and environmental factors can influence DNA methylation patterns in both rats and humans.
