The DNA in our cells is double stranded � there are two strings of nucleotides that are joined primarily by hydrogen bonds between the strands. We mentioned earlier that hydrogen bonds, when considered as individual bonds, are very weak. However, when we consider hundreds of hydrogen bonds together, a relatively strong and stable structure can result. Nucleotides from one strand make two or three hydrogen bonds with complimentary nucleotides of the other strand, depending on the nucleotide pair. The two strands together make up the helical DNA molecules that transfer genetic information from one generation to the next. Without these molecules, life would have a very difficult time perpetuating itself on the
