A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.
True labor contractions last more than 30 seconds at the onset and get progressively longer, up to 60 seconds, whereas false labor contractions vary in length and intensity.
The time between contractions includes the length or duration of the contraction and the minutes in between the contractions (called the interval). Mild contractions generally begin 15 to 20 minutes apart and last 60 to 90 seconds. The contractions become more regular until they are less than 5 minutes apart. Active labor (the time you should come into the hospital) is usually characterized by strong contractions that last 45 to 60 seconds and occur three to four minutes apart.
