There are two types of nucleic acids: deoxyribonucleic acid, better known as DNA and ribonucleic acid, better known as RNA.When a cell divides, its DNA is copied and passed from one cell generation to the next generation. DNA is organized into chromosomes and found within the nucleus of our cells.here are two types of nucleic acids: deoxyribonucleic acid, better known as DNA and ribonucleic acid, better known as RNA.

Cramps usually begin one to two years after a woman starts getting her period. Pain usually is felt in the lower abdomen or back. They can be mild to severe. Common menstrual cramps often start shortly before or at the onset of the period and continue one to three days.
cramps usually occur 2 to 3 days before your actual period starts. Some women don't even experience cramping at all while others have it really bad (the good thing about having bad cramps mean that you will have an easier child birth when delivering your children). It usually stops two days into your period so it should go away if you do have your period coming up.
