The 2 main nucleic acrimoniouss within the stall ar deoxyribonucleic acid (desoxyribonucleic acid) and ribonucleic acid (RNA). desoxyribonucleic acid and RNA serve as t individuallying carrying systems; information on the management of the cell. The subunits of a nucleic acid are homes. each nucleotide has a 5 carbon cacography, a phosphate group on star side of the sugar and a nitrogenous base unit on the other side of the sugar.
desoxyribonucleic acid has deoxyribose as its sugar. Adenine, thymine, quanine and cytosine are the 4 possible bases. The nucleotides are attached by the phosphate of one nucleotide being bonded to the sugar of the adjacent nucleotide. This creates a iterate backbone of sugar, phosphate, sugar, phosphate, etc. The base units extend out from the sugars. DNA in the majority of all organisms is double stranded. The base units of each strand link up using hydrogen bonds; amp pairs with thymine and guanine pairs with cytosine. The appearance of the double stranded DNA molecule is like a ladder. The backbones of alternating sugar-phosphate form the uprights of the ladder, with the encumber base units forming the rungs. In nature though, DNA is not a flattened molecule. Because of the natural bond angles between the elements, the molecule takes on a twist and looks like a spiral staircase.
Each cell possess only a single feign of DNA. If this DNA molecule were to be destroyed or mutated, the cell would die or not function properly. In eucaryotic cells, the DNA is contained in the organelle called the nucleus. The nucleus and its nuclear gasbag or membrane protects the DNA. The function of the RNA molecules is to perform the day to day functions of the cell. When a copy of the RNA deteriorates, it is destroyed and a new copy made from the master template or blueprint, the DNA. Transcription is the process by which RNA is made from the DNA. The DNA is unzipped and the RNA molecule is built from the DNA one nucleotide at a time. Only one of the strands of the DNA is get down;...If you want to get a full essay, order it on our website: Ordercustompaper.com
