7.3 Epigenetics

The process by which DNA is replicated

The process by which information from a gene is used to synthesize a functional gene product, usually a protein

The process of cell division

The process of genetic mutation

DNA sequence

Temperature

Chromosome number

RNA polymerase

Identical twins always have the same traits because they have the same DNA.

Identical twins can have different traits due to different environmental exposures, such as diet and lifestyle.

Identical twins have different traits because they have different genes.

Identical twins have different traits because they are born at different times.
