Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA is a polymer‚ which is a chemical compound or a mixture of compounds consisting of repeating structural units. These repeating structures are created through polymerization. The monomer‚ meaning one part‚ units of DNA are nucleotides. Each nucleotide consists of a five carbon sugar‚ also known as deoxyribose‚ and nitrogen containing base attached to the sugar

Sometimes‚ people don’t get along when they first meet‚ which is exactly the situation with Stewart and Ashley. In Susin Nielsen’s “We Are All Made of Molecules”‚ two families (the Inksters and the Andersons) move in together after the Andersons separate‚ and Stewart’s mom dies. It focuses on Stewart’s struggle to fit into his new school‚ and Ashley’s effort to maintain her reputation there‚ while coming to terms with her dad’s homosexuality. While Stewart changes immensely throughout the book‚ Ashley

If the temperature is increased‚ the molecules will gain kinetic energy allowing them to move a lot more frequently. Enzymes begin a reaction when they randomly collide with the substrate molecule‚ this is where the enzyme will react upon. The speed and frequency of these collisions is dependent on the temperature‚ so an increase in temperature will effectively increase the rate of reaction and allow more products to be made. Consequently‚ an increase in the temperature will make the vibrational

and the RNA World Learning Objectives: Students should be able to... • Sketch a nucleotide‚ label its three basic parts‚ and identify the 2’‚ 3’‚ and 5’ carbons. • Make another sketch showing the primary and secondary structures of DNA. • Describe the primary‚ secondary‚ tertiary‚ and quaternary structures of RNA‚ and explain in what ways RNA differs from DNA. • Explain why and how the secondary structure of DNA allows organisms to store and copy information. • Explain why RNA‚ and not

Objective : To extract the DNA from onion samples. Introduction : Nuclues has DNA molecule in it. It is packaged into thread like structure known as chromosomes. Each and every chromosome is made up of DNA tightly coiled many times around proteins which is known as histones. Histones supports the structure. Chromosome cannot be visible even under the microscope if the cells are not dividing. DNA consist of 2 long polynucleotide which is composed of 4 types of nucleotide units. Nucleotides

model can be used to explain why He2 molecules don’t exist. Combining a pair of helium atoms with 1s2 electron configurations would produce a molecule with a pair of electrons in both the bonding and the * antibonding molecular orbitals. The total energy of an He2 molecule would be essentially the same as the energy of a pair of isolated helium atoms‚ and there would be nothing to hold the helium atoms together to form a molecule. The fact that an He2 molecule is neither more nor less stable than

DNA Extraction Lab Problem Statement: Do you think you have ever eaten DNA? Background Information: DNA is too small to see under a regular microscope‚ so how can it be studied? DNA is a large molecule found in all living things; therefore it is possible to extract it from cells or tissues. All we need to do is disrupt the cell’s plasma membrane and nuclear envelope‚ make the DNA clump together and - voila! - DNA extraction is possible. DNA extractions from onion‚ bananas‚ liver‚ or wheat

Brain of the Cell The nucleus is literally a membrane-bound organelle and is surrounded by a double membrane. I feel that the nucleus is of the greatest importance in the cell because it is the control center that oversees the metabolic functioning of the cell and it directs all the cells activities. The nucleus is like the head of the cell and without a head the rest of the body is useless. It is the largest organelle and within the nucleus is the DNA responsible for providing the cell with its

is that RNA uses uracil instead of the thymine in DNA. DNA replicates itself and RNA is synthesized from RNA on an as-needed basis. Their stability and reaction is also different. DNA is more stable and less reactive than RNA because of the deoxyribose sugar’s C-H bonds. It is stable in alkaline conditions; DNA has smaller grooves‚ which makes it harder for enzymes to “attack.” RNA is more reactive because of the ribose sugar’s C-OH‚ hydroxyl‚ bonds. Unlike DNA‚ it is not stable in alkaline conditions
