Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA molecules are composed of two strands that form a helical ascending spiral. They fit together like the opposing teeth of a zipper and are held together by weak interactions called hydrogen bonds. These two strands is a long string of subunits called nucleotides‚ each attached to the one immediately about it and the one immediately below it to form a long chain. Each

Digestive system 6.1.1 explain why digestion of large food molecules is essential * Large food molecules are polymers‚ broken down into monomers in order to be absorbed into the blood * Humans eat substances by other organsims‚ many which are not suitable for human tissues therefore they must be broken down and reassembled in a form that is suitable * Many molecules in foods are too large to be absorbed by the villi in the small intestine‚ the large molecules have to be broken down

Biology Fermentation Practical "A comparison of the respiration of yeast in different sugar substrates" Aim: The aim was to compare the respiration of yeast in different substrates of sugars‚ i.e. between a monosaccharide (glucose) and a disaccharide (maltose) Theory: There are three types of Carbohydrates‚ monosaccharides‚ disaccharides‚ and polysaccharides. The two‚ which I will be looking at‚ are‚ monosaccharide (glucose) and the disaccharide (maltose) Classification and major properties of

self-replicating molecule‚ and describe at least one piece of experimental evidence that supports this hypothesis. Lecture Outline I. What Is a Nucleic Acid? A. What is a nucleic acid made of? 1. A nucleic acid is a polymer that is made up of monomers called nucleotides. 2. One nucleotide consists of a phosphate group‚ a sugar‚ and a nitrogenous base. (Fig. 4.1a) 3. The sugar can be either ribose or deoxyribose. (Fig. 4.1b) a. Ribonucleotides contain the sugar ribose; deoxyribonucleotides

Subject Content Most of the objectives specified in this section relate to Knowledge with Understanding‚ although some indication has been given as to where the skills of Handling Information and Solving Problems may be developed. Teachers are reminded that‚ in the written papers‚ 40% of the marks are allocated to these higher ’thinking’ skills. In almost every section‚ students should therefore be given practice at dealing with unfamiliar situations so that these higher thinking skills can be developed

Scientist say they can break down peel into simple monomers that can be used to make plastics and that there is no reason why the technology could not be in the wide use soon. The research team subjected orange peel to microwaves to
