What is the rule of DNA polymerase?
The DNA polymerase moves along the DNA (or RNA) template, extending the primer in the 5 3 direction according to the WatsonCrick base pairing rule, i.e., A pairs with T (or U) and C pairs with G (see Section II, Chapter 1).
How common is ATM gene mutation?
A-T is rare. It is estimated that A-T affects 1 in 40,000 to 1 in 100,000 people. The chance that a person is a carrier of a single ATM gene mutation is about 1%, or 1 in 100.
Does trauma alter DNA?
Our review found an accumulating amount of evidence of an enduring effect of trauma exposure to be passed to offspring transgenerationally via the epigenetic inheritance mechanism of DNA methylation alterations and has the capacity to change the expression of genes and the metabolome.
Does having a baby change your DNA?
Giving a whole new meaning to “pregnancy brain,” a new study shows that male DNA—likely left over from pregnancy with a male fetus—can persist in a woman’s brain throughout her life.
