Understanding the Functions of Proteins and DNA Ingrid Waldron‚ Biology Department‚ University of Pennsylvania‚ 2012 These key concepts and activities are suggested as part of an introductory unit on biological molecules (or as an introduction to a unit on molecular biology). The overarching goal is to help students understand that proteins and DNA are not just abstract concepts in biology textbooks but rather crucial components of our bodies that affect familiar functions and characteristics

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. * * There has been a major effort in the history of science to figure out the structure of DNA. Having a double standard helix DNA has a uniform a diameter in its entire length. The helixes fit within a defined three dimensional space because they are both right handed. Polynucleotide chains are held together by the bases in the (center) hydrogen bonding

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA really stands for Deoxyribonucleic acid. DNA is a right handed double helix. Nucleotides that mount together by phosphodiester bonds make up DNA. It also contains a spiral strand that is made of phosphate backbone and secure bases (Adenine‚ Guanine‚ Cytosine‚ Thymine). Cytosine and Thymine are Pyrimidines‚ while Adenine and Guanine are Purines.

Abstract This work describes the extraction of caffeine from tea leaves to determine its % caffeine. The extraction process selectively dissolves one or more compounds in a mixture into an appropriate solvent. In this experiment‚ it was visible in the process wherein the components of the tea leaves were dissolved in two solvents‚ water and dichloromethane (DCM)‚ with DCM used for multiple extractions. The organic layer was evaporated and the determined % caffeine was 0.12%. Furthermore‚ the purified

ABSTRACT The extraction of pectin from orange peels has been studied at different sample to solvent ratios‚ different PHs and with different extraction techniques using water. The amount of pectin extracted reduces as the PH increased. This research work is been carried out in order to determine the process condition that will result

How to make pencils? Background One of the oldest and most widely used writing utensils‚ the pencil originated in pre-historic times when chalky rocks and charred sticks were used to draw on surfaces as varied as animal hides and cave walls. The Greeks and Romans used flat pieces of lead to draw faint lines on papyrus‚ but it was not until the late 1400s that the earliest direct ancestor of today’s pencil was developed. About one hundred years later graphite‚ a common mineral occurring
