The EUROSION study (2004) recommends to deal with coastal erosion by restoring the. overall sediment balance on the scale of coastal cells, which are defined as coastal. compartments containing the complete cycle of erosion, deposition, sediment sources. and sinks and the transport paths involved.
Difference between DNA and RNA [edit]. DNA is the permanent genetic information storage medium, found in the nucleus of most cells of most living organisms. RNA is, in the case of eukaryotes, the medium that transfers the genetic information from the nucleus to the cytoplasm where proteins are synthesized.he bases of DNA are A,T,C,and G, DNA is a long polymer with phosphate and deoxyribose backbone. In contrast, RNA bases are A,U, C,and G, RNA backbone contain ribose and phosphate. The job of DNA on the cell is to store and transmit genetic information.
RNA plays a central role in the pathway from DNA to proteins, known as the  Central Dogma  of molecular biology. An organism's genetic information is encoded as a linear sequence of bases in the cell's DNA. During the process known as transcription, a RNA copy of a segment of DNA, or messenger RNA (mRNA), is made. This strand of RNA can then be read by a ribosome to form a protein. RNAs also play important roles in protein synthesis, as will be discussed in the ribozyme section, as well as in gene regulation.
