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.

How does transcription differ from DNA synthesis? The primary difference between transcription and DNA replication is that only a single strand of mRNA is produced during transcription. During DNA replication both strands need to be copied and DNA polymerase needs to work on both strands at the same time.Because DNA polymerase can only add new bases onto the free 3â end of a molecule the two strands cannot be synthesized in the same way. The leading strand is synthesized as a continuous chain.uring DNA replication both strands need to be copied and DNA polymerase needs to work on both strands at the same time.
