To transcribe the mRNA to make the DNA, we use genetic codes called codons. These are composed of three amino acids clumped together. It could be Adenine(A), Guanine(G), Uracil(U) and Cytosine (C). The difference is that first thread contains GUG, while the second one contains AGU. GUG is for Histidine while AGU is for Serine.
When forests have been cut down, new native trees can be planted
They both can be traced back millions of years ago
They are made from igneous, metamorphic and sedimentary rock.
