DNA (Deoxyribonucleic Acid)
DNA is a long molecule that contains each person's unique genetic code. It holds the instructions for building the proteins that are essential for our bodies to function.
DNA instructions are passed from parent to child, with roughly half of a child's DNA originating from the father and half from the mother.
DNA is what makes you special, alive and functional. Without DNA you would not exist. Everything you have, the thing you consider your best feature would not exist without DNA. DNA directs cell function.
If there was no DNA, cell division would not happen—therefore no differentiation, this means you would not exist neither would your pet. Even though DNA is not solely responsible for life as we know it is still arguably the most important factor. Other factors include the environment and experience.
In conclusion, DNA forms the basis for life.
The discovery of the DNA structure has led to major strides in research, medicine, agriculture and many other fields. Given how important this structure is to our existence, it only makes sense that its description has affected so many areas of our lives.
We hope at this point you have as much appreciation as we do for what DNA is and can do, how is differs from RNA, how many lives it has revolutionized and DNA fingerprinting.
At this point, you should also have an appreciation for what DNA is in biology and what it means for this field.
