The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions. The beauty of this structure is that it can unzip down the middle and each side can serve as a pattern or template for the other side (called semi-conservative replication).
Rupture of the uterus during pregnancy or labor is a serious emergency that can be fatal to both mother and fetus. Uterine rupture results in: 1  bleeding; 2  rupture of the amniotic sac (bag of waters); 3  partial or full delivery of the fetus into the abdominal cavity; and. 4  loss of oxygen delivery to the fetus.
Best Answer: Ectopic pregnancy is most commonly used to describe a pregnancy where the fertilized egg implants in the fallopian tube rather than in the uterine wall; however, it can also describe a pregnancy that occurs anywhere outside of the uterine wall. This can include the ovaries,bowel, or abdomen. Where the pain is located depends on exactly where the fertilized egg has implanted, so the pain will not be in the same spot for every ectopic pregnancy. If it is a fallopian or ovarian pregnancy, pain will be in the pelvis on the affected side. Symptoms usually do not develop until about 2 months into the pregnancy.
