they may begin to display subtle differences. They may start to look different,
develop different diseases or slide into different persons. 【M1】______
Women who are identical twins may differ with their fertility or 【M2】______
the age at which they reach menopause. These discrepancies
usually attributed to ill-defined differences in environment. 【M3】______

showing that identical twins, because they grow older, differ increasingly in【M5】______
what is known as their epigenome. The term refers to natural
chemical modifications that occur in a person’s genome shortly before 【M6】______
conception and that act on a gene as a gas pedal or a brake,
marking it for higher or lower activity. 【M7】______
Identical twins have the same set of epigenetic mark on the genome 【M8】______
when they are born. But differences in the epigenome disappear 【M9】______
as the twins grow older and become greater the longer they live together, 【M10】______
say a team of researchers led by Dr. Manel Esteller of the Spanish National Cancer Center in Madrid. [br] 【M8】
