Heat and steam j. Liquid e. Freezing t. UV The physical control of microbes is made up of [1] that can have an affect on their growth. By far the most effective one is the use of [2], which can [3] proteins at relatively [4] temperatures. A machine called an [5] is used in labs and clinical settings to [6] equipment, effectively eradicating all life on it. Some substances cannot handle moisture or heat, so instead a [7] such as [8] can be used. This is most often seen used with paper products. Some physical control methods are [9] meaning they kill microbes, while others are considered [10] meaning that they halt their reproduction but don't necessarily kill them. [11] is an example of a process that is often used to preserve bacterial specimens by removing all of the water from the cells at low temperatures. [12] can be used as a physical control in some cases, and it affects the cells exposed to it at the DNA level of organization. [13] light and [14] rays are commonly used from this category. Finally, [15] is the process of physically straining a [16] or even air through a substance with [17] that trap particles including bacteria and viruses, like a strainer.
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
