Andrew Eguia Dr. Harjani Medical Biology P5 2/14/12 Chapter 11 Review P216 1. DNA consists of subunits called nucleotides. Each subunit consists of three parts: sugar (deoxyribose)‚ phosphate‚ and base. 2. The subunits of DNA are assembled by linking the sugar of one nucleotide to the phosphate of the next. As it is found in chromosomes‚ two DNA polymers are bound together into a structure called a double helix. 3. The “base-paring rule” in DNA is that adenine pairs with thymine

Final Biology Exam Review Unit One: Cellular Processes Definitions: Apoptosis – Known as cell suicide‚ lysosomes break open and decompose the entire cell. Triglyceride – A lipid molecule composed of glycerol and three fatty acids. Simple diffusion – Movement of particles from an area of high concentration to an area of low concentration. It goes through the phospholipid bilayer. Facilitated diffusion – Diffusion of particles through the cell membrane‚ assisted by transmembrane proteins

little but the BMR of the normal rat was still bigger and so the dose was too small. 10. The hypophysectomized rat’s BMR increased from the TSH‚ but yet again‚ the normal rat’s BMR was still more‚ so the TSH dose was again too small. Part 4: 11. The normal rat’s BMR decreased from the PTU injections and it developed the palpable goiter because of build up of the precursors to thyroxine. 12. The thyroidectomized rat’s BMR was not effected by PTU injections. In this case‚ the BMR is still
