Typically, DNA is created from RNA, and this is done by faithfully copying the sequence of base pairs, with the only change converting T to U. Hence, an RNA copy of a DNA sequence encodes the identical information, though it uses a slightly different set of 4 substances.
Soil organic carbon is part of the natural carbon cycle, and the worldâs soils holds around twice the amount of carbon that is found in the atmosphere and in vegetation. Organic material is manufactured by plants using carbon dioxide from the air and water.he amount of soil organic carbon present in soil can vary hugely according to soil and landscape types,an and c climate an change in the same paddock over time depending on climate and farming methods.
Why are soils important? Soils are a vital natural resource as they carry out a wide range of essential functions, such as growing food and timber, controlling the quality and quantity of water flow, supporting valuable habitats and species, and storing carbon. Although we may not realise it, soils affect many parts of our everyday lives.
