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.

While the DNA remains in the nucleus, it controls most of the processes that occur in the cytoplasm of the cell. Information from the DNA can be transcribed to mRNA and transmitted to other cellular synthesis processes, and information from the cytoplasm can provide feedback to the nucleus.The nucleolus is the central portion of the cell nucleus and is composed of ribosomal RNA, proteins and DNA.It also contains ribosomes in various stages of synthesis. The nucleolus accomplishes the manufacture of the ribosomes.he nucleolus is the central portion of the cell nucleus and is composed of ribosomal RNA, proteins and DNA.
