River of Rocks. You can turn drainage solutions into features that enhance your landscapeâand protect natural waterways. Ditches can be landscaped as swales that look like creek beds or small meadows. Gutter water can flow into rain gardens that provide a habitat for butterflies and birds.
Introduction. DNA is the molecule which controls the synthesis of proteins. Proteins are used for growth and repair and also as enzymes, in which form they catalyse all other cellular activities. Thus DNA is able to exert a controlling influence over the whole cell and ultimately, the whole organism.The segments of DNA which hold the key to this control are the genes.roteins are used for growth and repair and also as enzymes, in which form they catalyse all other cellular activities.

Deoxyribonucleic acid (DNA) synthesis is a process by which copies of nucleic acid strands are made. In nature, DNA synthesis takes place in cells by a mechanism known as DNA replication.Using genetic engineering and enzyme chemistry, scientists have developed man-made methods for synthesizing DNA. The most important of these is poly-merase chain reaction (PCR).hile the process of DNA replication was know before 1980, PCR was not possible because there were no known heat stable DNA polymerases. DNA polymerase is the enzyme that catalyzes the reactions involved in DNA synthesis. In the early 1980s, scientists found bacteria living around natural steam vents.
