The barley genome has 5.3 billion bases (letters of genetic code) – this makes it almost twice the size of the human genome. This is the first complex grass genome to be sequenced and annotated.

Researchers have made synthetic genetic material, called XNA. This uses six altered bases, made from the existing ‘letters’ in DNA, thymine, adenine, guanine and cytosine (T, A, G and C). The synthetic XNA could replicate and evolve. This could help us learn about how DNA began, and could one day lead to creation of synthetic life, though that is a very long way off.

Researchers have sequenced the whole of the human genome – if you typed out the sequence at 60 words a minute for 8 hours a day it would take you about 50 years to finish.
