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.
If we have a laboratory test for bacteria in our water supply, these common water bacteria would probably show up in the test. 1. Coliform bacteria. Coliform bacteria are the most common strains of water bacteria. They live in the soil and in the intestinal tracts of animals.They can get into the water supply through direct disposal of animal waste into the water or by runoffs from wooded areas, septic tanks and sewage.acteria are common in the home water supply. Just because the water that comes from our tap looks clear and does not smell funny does not mean that it is pure. There is actually no such thing as âpureâ water.
