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.
Also, just for future knowledge, how long are contractions at each stage supposed to last for so I can try and tell the difference. The pains I am... show more I am 34 weeks and starting to get some more painful BH contractions that maybe last 5 seconds or so.
