DNA comes in molecules which retain information such as blueprints for a building. DNA contains the genetic instructions needed to facilitate the developing and functioning of all living organisms. DNA comes in the form of a strand which is located within the nucleus. This Article was originally published on The Conversation. DNA stands for Deoxyribonucleic acid, which is the basis for all human beings. A previous version stated that the 9th letter in the example DNA strand was an A. This article has been amended to correct an error. Reading someone’s DNA allows doctors to spot and treat these diseases before they become too bad.

This might cause some of your cells to not work properly.įor example, just one wrong letter in one particular gene might mean someone is more likely to become diabetic, or get cancer when they are older. Reading DNA is useful because sometimes the letters in the genes aren’t quite right, like a misspelled word in a set of instructions. By putting that all together, she can read the whole DNA sequence. She then does exactly the same thing with the other tubes and works out that the 1st and 6th letters are Ts, the 3rd, 4th and 9th letters are Cs and the 7th is a G. The information coded in DNA is hereditary. DNA is a vitally important molecule for not only humans but also most other organisms.

#Dna stands for manual#
By doing this, she can work out that the 2nd, 5th and 8th letters are all As. Think of this code as an instruction manual for making all the proteins that form our bodies and help them thrive. It contains units of biological building blocks called nucleotides. She then counts how many pairs are in each strand of DNA.

The scientist reading the DNA knows that each strand in this tube ends in an A*.
