Which of the following explains why Epigenetics are different than mutations, in that mutations?
Can be inherited.
Cannot be inherited.
Can change DNA sequences.
Can change traits.
The correct explanation that differentiates Epigenetics from mutations is that mutations can change DNA sequences and can be inherited, whereas epigenetics cannot change DNA sequences and cannot be inherited.
Epigenetics refers to heritable changes in gene expression that do not involve alterations in the DNA sequence itself. These changes occur due to modifications to the DNA or associated proteins, such as DNA methylation or histone modifications. Epigenetic modifications can influence gene expression patterns and cellular behavior without changing the underlying DNA sequence. Importantly, these epigenetic changes can occur throughout an individual's lifetime but are generally not passed on to future generations.
On the other hand, mutations are changes in the DNA sequence itself. Mutations can, therefore, result in alterations in gene function or protein structure. Mutations can occur spontaneously or be induced by various environmental factors, such as exposure to radiation or chemicals. Importantly, mutations can be inherited if they occur in the germ cells (sperm or egg cells) and are subsequently passed on to offspring.
