The enthalpy for hydrogenation of different isomers of butene is shown in the following figure. Which statement below best interprets this figure.

According to the Hammond postulate, what structure does the transition state resemble?

Epigenetics describes heritable traits that are not linked to changes in DNA sequence, but to chemical reactions that regulate the transcription of the genes. A common event is methylation of lysine residues on histone proteins, which results in regulation of gene expression.
