Final answer:
c) Epigenetic changes involve alterations to the DNA sequence is the false statement about epigenetic regulation.
Step-by-step explanation:
The false statement about epigenetic regulation is: c) Epigenetic changes involve alterations to the DNA sequence.
Epigenetic regulation refers to changes in gene expression that do not involve alterations to the underlying DNA sequence. Instead, epigenetic changes involve modifications to the chromosomal structure, such as DNA methylation or histone modifications, that can influence gene expression. These changes are reversible and can be passed on to offspring, making epigenetic regulation an important mechanism for gene control.
For example, DNA methylation is an epigenetic modification that involves the addition of methyl groups to certain regions of DNA. This modification can lead to the silencing of genes, preventing them from being transcribed into RNA. Environmental factors, such as ultraviolet light exposure, can also influence epigenetic regulation by causing changes in DNA methylation patterns and gene expression.
