DNA+(Questions+1+&+2)


 * 1. What is DNA and where is it found? **
 * DNA is short of Deoxyribonucleic Acid. It is the hereditary material in all humans and almost all the other organisms. Almost every cell in your body contains the same exact DNA. Most DNA is found in the cell nucleus, called nuclear DNA, but some can also be found in the mitochondria. **




 * 2. What does it look like (its structure) and what is it made from? **
 * A DNA molecule looks like a long, twisted ladder, called a double helix. The sides of the “ladder” are a linked chain of alternating sugar and phosphate molecules. The “rungs” of the “ladder” are known as bases. **
