DNA is a molecule which stores the information for the making of all the proteins that a cell will need. Usually, a single gene only codes for a single protein. A DNA molecule consists of two strands …

These rocks are 250 million years old, laid down in the Early–Middle Triassic period, which is 5 million years older than any previous dinosaur tracks. It is just a couple of million years …

Amino Acids In Space…
I often bang on about amino acids as the building blocks of proteins. Plants can make them from carbohydrate they make themselves through photosynthesis and nitrates absorbed from the soil; you get them from your diet. Your genes are codes for individual proteins which are constructed from chains of amino acids. One of the first …

The theory of evolution is often seen as the basis of modern biology, indeed it has been said that nothing in biology makes sense without evolution. Evidence from fossils, the geographical distribution of organisms and recent discoveries about genes all support the theory that organisms have changed over time. These changes are incredibly slow and …
