The double helix is the most recognizable structure for deoxyribonucleic acid, also known as DNA. Double helix is the name for the structure formed by double-stranded molecules of nucleic acids. In short, it the the shape of the molecule where all the genetic information is stored for all organisms.
Inside every cell of each living thing, both plant or animal, there are sets of instructions called genes. The genes provide the instructions on what is the plant or animal, what it looks like, how it is to survive, and how it will interact with its surrounding environment. The genes are strung together in long stands of material called deoxyribonucleic acid (DNA) and these long strands are called chromosomes. Most living things have pairs of chromosomes (one from each parent), though they may have a different number of chromosomes from another living thing. For example, humans have 23 pairs of chromosomes and the fruit fly has 4 pairs.
Each gene is made up of long combinations of four different nucleotide bases. It is the various combinations of the nucleotide bases that determine everything about a living creature.
Science Saturday adjourned. Now, with any left over min-marshmallows, get out your marshmallow shooter, load it up and have some fun.
