Science and DNA
Technically, science is a systematic study about physical and natural phenomena that includes all aspects of which. It is acquired through observation and experiments.
One very important part of science is the thing called deoxyribonucleic acid (DNA) that is present is most living organisms. It is a type of organic substance called nucleic acid, and contains instructions about the genes of living organisms that are vital for their functions, development, and growth.
It is known that all things, from bacteria to humongous trees, contain these DNA. Some of the viruses that attack man and bring harmful causes also contain their own DNA.
The most important job of DNA in cells of organisms is to contain genetic information for a very long time. People usually term DNA as the "blueprint of life", because it stores orders that build up other parts of cells, like the proteins, that are important for the making of the whole organisms.
DNA are usually arranged into segments, which together pack up DNA information and carry them. These segments are called genes. Not all DNA segments do this job, however. Because some help in the structure of the cells and eventually contribute to the expression of the information contained in several genes.
Eukaryotes, which are organisms that contain true nucleus like plants and animals, hold these DNA inside their nucleus. On the other hand, organisms that do not have real nucleus like archaea and bacteria, contain their DNA in the cytoplasm of their cell.
Enzymes, as we know, speed up chemical reactions and therefore act on other molecules. DNA, however, does not do the same job. Instead, different enzymes help DNA to replicate its information into another DNA, or for the process of DNA replication, or for its transcription into proteins of cells.
Proteins help pack up DNA and also help repair DNA damages that may cause mutation to the cell and eventually affect the whole organism.
DNA is made of one tiny units called nucleotides, which makes it a polymer. These units are linked together by a backbone consisting sugars and groups of phosphates. These backbone contain four different types of bases. The arrangement of these bases is the reason why DNA information are encoded.
DNA is the one that encodes the units of proteins that are called amino acids. This is its main purpose. It makes use of the entire genetic code. In order to comprehend the genetic code, DNA are copied through riboxynucleic acids. These copies of RNA are then utilized to direct the synthesis of protein molecules. Moreover, RNA can be also be useful as parts of ribosomes which are another type of organelle vital for the cell.
DNA is very important as it determines the uniqueness of every organism that is living. To test the DNA, DNA kits are used. In the world of science, DNA identification entails DNA size selection and DNA extraction as well as purification.
