Nucleic Acids are the sole reason we human beings are different from a banana, from an elephant, or from a chimpanzee. All living things in this world are unique because of the order of 4 bases arranged in different patterns to form DNA. DNA is the blueprint for every organism. The blueprint needed to build us resides in most of our cells. This information is a sequence of four nucleotides arranged in a specific pattern. For example, cows have 80% of a human's DNA. DNA provides the map of the proteins and genes we express in each individual, and without it, we would be a totally different person. Besides DNA, nucleic acids also perform other functions in our body, but the role it plays in the formation of DNA is the most important.
Let's break down what DNA really is. DNA stands for Deoxy-ribo Nucleic Acid. Deoxy means that there is a missing oxygen atom in the sugar on the second carbon in DNA. It is the only chemical difference between the sugar molecule Deoxy-ribose and the regular sugar ribose. Ribo means that there is a sugar. Now, what does the word Nucleic mean? The word comes from a German word Nuklein, meaning comes from the nucleus. Therefore, DNA is an acid that has sugar, but has no oxygen. DNA is made of nucleotides, but what does that really mean? There are only 4 types of nitrogenous bases in DNA: adenine, thymine, cytosine, and guanine. All 4 of these are nucleic acids. These bond together with a Hydrogen bond. Adenine bonds with thymine, and cytosine bonds with guanine. The “backbone” of the DNA is the phosphate group and the ribo group bonded by covalent bonds. What is the difference between RNA and DNA? Well, as discussed before, there is one oxygen atom missing from the sugar in DNA, but there are more di...

Living things are only each different because of the order of the 4 bases arranged in different patterns to form DNA, our genetic material. The blueprint of DNA that is needed to build us is in most of our cells. These directions are sequences of four nucleotides arranged in a pattern. DNA gives us the map of our proteins and genes we have. Besides just DNA and RNA, nucleic acids also do other things in our body, but the role it plays in the formation of DNA is the most important.

The Midwife’s Role in Informing Pregnant Women of the Importance of Folic Acid

- How the provision of information in the antenatal period can positively affect health and life style choices in the pregnant woman and her family. It is a recognised certainty that nutrition is a fundamental requirement to sustain a healthy lifestyle and is also extremely valuable when recovering from an illness or an injury. Nutrients are absorbed in the body and this physiological process is essential for homeostasis and ensuring equilibrium is sustained within the body as without enough food and drink the body will not function correctly (Edwards & Thomas, 2009)....   [tags: Importance of Folic Acid]

Essay on A Structure For Deoxyribose Nucleic Acid

- There is a popular saying that states: “Two heads are better than one.” Many believe that human beings work more efficiently and make more reasonable decisions when working in a group. Collaboration is an action that is present in every social group, in every workplace, and in every field. However, human beings are also highly competitive. Like collaboration, competition is present in every aspect of life. Undoubtedly, collaboration and competition have provided a path to innumerable achievements in many fields, and science is not an exception....   [tags: DNA, Francis Crick, James D. Watson]

Notes On Deoxyribose Nucleic Acid Essay

- ... The tRNA travels to the P-site of the ribosome where protein synthesis begins.2 The ribosome moves along the mRNA and creates a polypeptide chain. Translation is a 3 step process consisting of initiation, elongation, and termination. Initiation is the process where the mRNA and tRNA creates the first two amino acids.2 The first codon for protein synthesis is always AUG, which is start codon that codes for Methionine. During elongation, amino acids are added onto the growing peptide chain. Termination occurs when the ribosome reaches a stop codon on the mRNA (either UAA, UAG, or UGA), which causes the polypeptide chain to break away from the ribosome.2 The process of transformation ener...   [tags: Protein, DNA, Nervous system, RNA]

The Utility of Nucleic Acid Hybridisation and Nucleic Acid Probes In Molecular Biology

- The unique property of nucleic acids to pair with each other through complementary base pairing is the lifeblood of genetic engineering. A single strand of DNA can pair up with another strand of DNA or RNA if its base pairs are complementary to those of the other strand, under the right conditions of temperature and pH. This phenomenon is called nucleic acid hybridisation. It is possible to exploit this mechanism for the detection of one nucleic acid strand from a mixture of many other strands....   [tags: Molecular Biology]

Essay about Haematological Malignancies and Nucleic Acid Therapeutics

- It’s Not Just a Nucleic Acid - Aptamer conjugates,Systemic delivery would be advantageous and provide more clinical appeal, in spite of the above mentioned limitations, and it is now becoming more common to link the RNAi to compounds, such as ligands or peptides to achieve target specificity and nuclease resistance, thereby eliminating some of the non-targeted effects (Bhindi et al 2007). Aptamers represent a unique alternative in the ability to specifically target cancer cells. Aptamers have been developed that target both extracellular protein ligands, as well as intracellular proteins....   [tags: Biology, RNAi]

The Structure of Nucleic Acid Chains Essay

- The Structure of Nucleic Acid Chains Nucleotides are joined together in DNA and RNA by phosphate ester bonds between the phosphate component of one nucleotide and the sugar component of the next nucleotide. An ester bond is a bond which occurs between a Carbon atom and an Oxygen atom. More and more nucleotides can be added on by the same process of forming ester bonds until an immense chain is formed. But no matter how long a polynucleotide chain is, one end of the nucleic acid molecule always has a free -OH group on the sugar at the Carbon known as C3' (called the 3' end) and the other end of the molecule always has a phosphoric acid group at C5' (the 5' end)....   [tags: Papers]

Chemistry of PNA Peptide Nucleic Acid Essay

- Abstract For this report I chose to study PNA, or peptide nucleic acid, a biological polymer that was related to the biomedical field of research. I was very interested in this synthesized molecule because of its inimitable and remarkable properties, comparatively to other nucleic acids such as the more commonly known DNA, or deoxyribonucleic acid, and RNA, or ribonucleic acid. I also wanted to understand its uses and possible uses in everyday life. My main goal was to learn about the structure, significance, and clinical applications of PNA....   [tags: Biology Polymer Medical Biomedical]

A Short Note On Non Coding Nucleic Acid Regulators Of Messengerrna Essay

- As mentioned earlier, miRNAs are short, non-coding nucleic acid regulators of messengerRNA (mRNA) stability and translation that play diverse roles in development and disease. MicroRNAs are highly conserved RNAs, 18–25 nucleotides in length, that regulate gene expression. A highly conserved gene does not change from one species to another. It has the ability to remain unaltered in its genetic makeup. This generally suggests that the species are closely related. MicroRNAs are effective at adjusting or modifying proteins that are responsible for cell signaling pathways and involved in cellular and developmental processes....   [tags: DNA, Gene, RNA, Molecular biology]

Chloroplast Fractionation : Nucleic Acid And Protein Analysis Via Gel Electrophoresis

- Chloroplast fractionation: Nucleic acid and protein analysis via gel electrophoresis ABSTRACT: Chloroplasts carry out photosynthetic processes to meet the metabolic demands of plant cells (Alberts, 2008). They consist of an inner thylakoid membrane and a stroma. (Parent et. al, 2008).In this experiment we demonstrate the unique protein compositions of isolated thylakoid and stromal fractions from broken and whole spinach chloroplasts. Because these compartments carry out different metabolic processes, we confirm our hypothesis that performing SDS-PAGE on these fractions will result in distinct patterns on the gels....   [tags: DNA, Molecular biology, Polymerase chain reaction]
