- DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher

- Many people though believe that DNA was discovered by American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s

DNA acts as a instructions for the body to break down proteins in to amino acids for our body’s to use in order  to grow and develop

- DNA is a double-helix molecule built from four nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C)

- DNA is present in each and every  of human body. Each DNA strand is 1.8 meters long but squeezed into a space of 0.09 micrometers

- If we unravelled the entire DNA in a human, it would stretch 10 billion miles. That would be the same as a return trip to Plut

DNA stands for deoxyribose nucleic acid, it's form is shaped like a double helix. the video below gives a better introduction to this subject

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The 4 types of nitrogen bases are adenine, thymine, guanine and cytosine. The order of these bases is what determines DNA's instructions, or genetic code

All living things have a genetic code called DNA, this is essential to life as we know it. in short, DNA tells our body what to do, which proteins to make and has many other
