Adhesion How does temperature change affect surface tension? As the temperature of a liquid increases‚ its surface tension decreases. When water heats up‚ the movement of its molecules disrupts the imbalanced forces on the surface of the water and weakens its sheet-like barrier of tightly bound molecules‚ thereby lowering the surface tension. This is why hot water is more effective when cleaning; its low surface tension allows it to more easily penetrate the fibers of a material like fabric

Transcription and Translation The function of DNA in the living world is at once strangely complex and surprisingly simple. The genetic code carried in molecules of DNA is responsible for a spectacular variety of life forms. Plant life in the Amazon‚ creatures on the ocean floor‚ and animals in the Serengeti have all arisen‚ and survive and thrive in their respective environments‚ because of the function of DNA. Inside every living cell‚ DNA directs vital activities‚ such as growth‚ division‚ movement

TUTORIAL 9 - Student Genetics: Transcription and Translation AIMS: 1. To understand keywords and use them as an aid to study facts 2. To get a better understanding of transcription and translation LEARNING OBJECTIVES: 1. Comprehensive reading 2. To associate certain facts with each other‚ therefore creating a bigger picture Exercise 1a: Firstly‚ fill in the structure names for each picture. Secondly‚ describe in a short paragraph what u looking at‚ where u find it and the

antiparallel double helix molecule with sugar-phosphate backbone on the outer side and nitrogen bases in the inner side. The bases are paired specifically‚ also known as complementary pairing‚ Adenine (A) with Thymine (T)‚ and Guanine (G) with Cytosine (C) by two and three hydrogen bonds‚ respectively. DNA is a long polymer of nucleotides (a polynucleotide) that transfers the information to RNA (mRNA) that in turn controls the sequence of amino acid residues in proteins‚ using the genetic code

DNA Research Paper DNA Structure: DNA (deoxyribonucleic acid) is the code for life; it makes up the genetic material of living organisms. DNA is a long molecule made up of many subunits‚ or monomers‚ called nucleotides. Nucleotides are made up of three parts: a sugar‚ a phosphate group‚ and a nitrogenous base. Nucleotides contain a sugar-phosphate backbone and bases. There are four bases in DNA: adenine‚ cytosine‚ guanine‚ and thymine. A (adenine) always pairs with T (thymine)‚ and C (cytosine)

Experiment 2: Transcription and Translation 1. Use a pen or pencil to write a five word sentence using no more than eight different letters in the space below. Tea is a never ever 2. Now‚ use the red‚ blue‚ green‚ and yellow beads to form “codons” (three beads) for each letter in your sentence. Then‚ create codons to represent the “start‚ “space” and stop” regions within your sentence. Write the sentence using the beads in the space below: E: red:green:red I: Blue:red:blue T: blue:yellow:green

2 Production of Protein from Cloned Genes Now that we have covered the basic techniques involved in gene cloning and DNA analysis and examined how these techniques are used in research‚ we can move on to consider how recombinant DNA technology is being applied in biotechnology. This is not a new subject‚ although biotechnology has received far more attention during recent years than it ever has in the past. Biotechnology can be defined as the use of biological processes in industry and technology

Study Guide 3/1/11 1. Describe the three parts of a nucleotide and how they bond to form a nucleotide. The three parts of a necleotide are a carbon sugar‚ a phosphate group and a nitrogenous base. The carbon sugars bond to the phosphate groups by covalent bonds while the nitrogenous base bonds with it’s compliment by hydrogen bonds. 2. Summarize the role of covalent bonds and hydrogen bonds in the structure of DNA. The role of covalent

Produced by cell clusters in the pancreas called the Islets of Langerhans‚ insulin is a hormone that regulates glucose concentration in the blood. It is a protein synthesised and stored by beta cells‚ which secrete it in surges responding to changes in glucose levels. (Hardin‚ Bertoni and Kleinsmith‚ 2012) Fig 1.
