Nucleic acid Essays

gnment 1 pass 1 Nucleic Acid Structure Similarities Differences DNA It has a double helix structure with phosphate and sugar molecules along the side and the nitrogenous bases up the centre which include adenine cytosine thymine and guanine. DNA and RNA are both found inside the nucleus. Like DNA, RNA is a linear polymer made of four different types of nucleotide subunits linked together by phosphodiester bonds DNA is the only double stranded nucleic acid. DNA is also only found in the

Concept 3.1: Nucleic Acids are Informational Macromolecules Nucleic acids are polymers and there are two types, Dna and Rna. Dna is where the information is stored and determines how functions in the body is carried out and Rna how mediates the information. The monomers of nucleic acids(polymers) are made up of nucleotides. Nucleotides are made up of three parts:nitrogen containing base, a pentose sugar and anywhere from 1 to 3 phosphate groups. Nucleosides are molecules that have a pentose and

1) How does RNA differ from DNA? RNA is different from DNA in many ways. Firstly, DNA is double stranded whereas RNA is only a single strand. The sugar present in RNA is ribose whereas it is deoxyribose (one more OH) in DNA. Also, Bases in RNA are A, U, C, G (adenine, uracil, cytosine, guanine) whereas bases in DNA are A, T, C, and G (adenine, thymine, cytosine, guanine). Where DNA contains genetic material, RNA copies the material and helps to synthesize it into protein. Also, DNA has deoxyribose

Forensic sciences is the term given to an examination and investigation of a crime using scientific means. Forensic science is a fundamental instrument for the recognition or investigation of crime and the ruling of justice, depending on data and information about the evidence found at crime scene. The validity of those results relies on the knowledge, abilities, and experience of the forensic scientist attempting to get them. A forensic researcher must be equipped for incorporating learning and

for a single amino acid because the DNA has 4 letters (A, T, G &C), which have to specify the twenty different amino acids that create up proteins. One DNA letter for one amino acid can only code 4 maximum amino acids, if 2 letters could code up to 16 amino acids, however 3 DNA letters are more than enough combination which can code for all 20 amino acids, and this is why it is a triplet code. The order and number dictated by the number of the the base triplet create an amino acid. The degenerate code

1. alpha helix- A type of secondary structure that looks like a spring. 2. amine- the generic name for molecules that contain an amino group 3. amino acid- Molecules that contain both an amino group and a carboxyl group. 4. amino group- When a carbon skeleton has a nitrogen bonded to two hydrogens. 5. anabolic steroids- Man-made versions of testosterone. 6. carbohydrate- A macromolecule that includes monosaccharides, disaccharides and polysaccharides. 7. carbon skeleton- Carbons, when bonded

Proteins, starches, lipids and nucleic corrosive. I will likewise depict the capacities and why they are critical in our bodies. Proteins Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then collapsed into a three-dimensional structure one of a kind to every sort of protein. The covalent linkage between two contiguous amino acids in a protein (or polypeptide) chain is known as a peptide bond. There are twenty amino acids that make up proteins. Every amino

Proteins and Nucleic acids are two different macromolecules that are not similar in structure and function.Proteins are a polymer of amino acids. Nucleic acids,on the other hand is a polymer of nucleotides composed of a pentose sugar , a nitrogenous base and a phosphate group.proteins play many important roles in human body including maintenance of structure of cells,regulating mitosis and meiosis,and also controlling body’s metabolism.Main role of nuclec acids(DNA & RNA) is to store the genetic

DNA stand for deoxyribonucleic acid. RNA stands for ribonucleic acid. They share some similarities, such as both being nucleic acids. Nucleic acids are long macromolecules that consist of a long chain of nucleotides. Both DNA and RNA have five carbon sugar and four nitrogen containing bases. In addition, DNA and RNA can be found in the nucleus of the cell. They are also vital to organisms. They are key to genetic information being created and distributed to various parts for the cell.

titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌ H2CO3 The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due

waters (Environment Canada 2012). Through a dual oxidation process, Nitrate is formed in a reaction of Nitrogen with Ammonium ion producing fertilizer and manure. The oxidation state of a nitrate compound is 1- . Nitrate is the conjugate base of nitric acid (HNO3), a strong

role of stomach acid Chapter 14 section 1 Noopur Rajendra Grade – 11AA 25/04/2016 Ms. Sara Kassem Sharjah American International School Discuss the role of hydrochloric acid in the digestion of foods. Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produces. Abstract Hydrochloric acid, which is also called HCl, is a highly corrosive acid. It is a strong

oxygen in extreme cases it could cause death. It could react with other chemicals causing more sickness. If you consume nitrate then you could just get small stomach flu, but when pregnant, or a baby it could cause much worse because your stomach acids are different.

The aim of the investigation was to determine the effect of pH on the rate at which catalase decomposes hydrogen peroxide and consequently answer the researchable question “How does pH influence cells and consequently an organism”. The hypothesis, “As the pH deviates from 7 the initial rate of oxygen production will decrease” is supported by the results. The trend displayed in Figure 3 is, as the pH deviates from 7 the initial rate of reaction decreases. Figure 3 shows that the rate of reaction (%O2/s)

The temperature of the water was then recorded to the nearest 0.1⁰C. Then the melting points of phenylacetic acid, o-anisic acid, and benzilic acid were determined by the use of a Mel-Temp. The unknown sample was obtained from the chemical stockroom. A small scale of crystals from unknown was placed in a test tube with the following solvents: cyclohexane, hexane, toluene, diethyl

The objective of the Bromocresol Green Equilibrium System Lab was to determine if the equilibrium constant, K, was a true constant at constant temperature. To determine this, the value of the constant was found at different concentrations of HIn, HIn-, and at varying pH, which was used to determine the concentration of H+. K was found using the equation K= [HIn]/([In-][H+]). In order to be a true constant, none of the values of K found should differ from the average by more than two standard deviations

hydoxyproline, Serum ascorbic acid, Serum calcium, Urinary calcium, Serum sialic acid, Serum hexosamine, Serum inorganic phosphate were estimated by spectrophotometic method. Result: The study

This 1938 Palmolive soap bar advertisement utilizes its art style along with rhetorical devices such as logos, pathos and ethos. Logos is being utilized through the doctor 's recommendation as well as mentioning on how it helps reduce dry skin. The advertisement also cites the rhetoric device of pathos by using scare tactics to convince its readers to use Palmolive soap. Ethos is presented to encourage the use of Palmolive soap through the notion that women are wanting to look beautiful for their

The Gatorade ad is effective because it appeals to sports fans and athletes and self-actualization needs.It features a basketball player, Dwyane Wade, drinking a bottle of Gatorade.He takes up the entire page and has his back to the camera. Wade is looking up towards something in the distance. The orange color of the Gatorade bottle stands out against the background, which is faded. There is a gym in the background with a window at the top left of the page , with a faded Miami Heat logo near the

Discussion: In this experiment, freezing point depression was used to determine the molar mass of three unknown solids. First, the freezing point of the mixture of ice and water was determined, as freezing occurs when both the solid and liquid phases pre-present together. The temperature when the ice and water mixture reached equilibrium was recorded. Then, the solution of the unknown solids was prepared and its freezing point was determined. Then the equation of molarity allowed the experimenters
