Answer by Ridens. Confidence votes 2.8K. They are both nucleic acids. Regarding structure, DNA and RNA are similar because they are both built of nucleotides, structures consisting of one nucleobase, a sugar (ribose or deoxyribose respectively) and a phosphate group.For both of them, their function is mainly containing information in the form of code, using 4 different bases.nswer by Ridens.

The most common non-pathogenic bacteria found in water is iron bacteria. Iron bacteria can be readily identified by the red, feathery floc that forms overnight at the bottom of a sample bottle containing iron and iron bacteria.acteria are tiny organisms occurring naturally in water. Not all types of bacteria are harmful. Many organisms found in water are of no health concern since they do not cause disease.
