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.

DNA is composed of nucleotides that are joined by phosphodiester bonds. DNA synthesis, which takes place in the nucleus, is a semiconservative process, which means that the resulting DNA molecule contains an original strand from the parent structure and a new strand.NA synthesis is initiated by the RNA polymerase primase, which makes an RNA primer with a free 3âOH. This primer is attached to the single-stranded DNA template, and DNA polymerase elongates the chain by incorporating nucleotides; DNA polymerase also proofreads the newly synthesized DNA strand.
