Lecture 11: Cytoskeleton in Action Slide 2: Mysoin V can walk a lot faster than Myosin 2. Saccharomyces Cerevesiae is a type of yeast. Myosin V interacts with one end of the nucleus‚ and another binds to the other side to orient the nucleus. Slide 3: The entire cytoplasm moves in one side: “streaming”‚ what happens is that very close to the membrane‚ the chloroplast are not moving and close to it are the actin filaments that are not moving. Then everything else is on the Myosin V which is moving

INTRODUCTION Levels of organization (cell to biosphere) and characteristics of life Levels: Cells->tissue ->organs & organ systems->organisms->populations->communities->ecosystems-> biosphere Characteristics of life: Cell and Organization: Each cell can only do the job it is tasked with. Example: brain cells Energy Use and Metabolism: Energy is needed many organisms. Energy is utilized in chemical reactions Response to Environmental Changes: responds to stimuli Regulation and Homeostasis: ex:

Article Review: Cancer 1. Gibbs‚ W W. "Untangling the Roots of Cancer." Scientific American July 2003: 56-65. Print. 2. In the human body‚ cells are constantly going through the cell cycle. An important step of the cell cycle is called mitosis‚ in which the cell (referred to as the parent cell) undergoes a series of steps that lead to the formation of two daughter cells. This process only occurs in somatic cells‚ which are any non-gamete cells. Gametes are haploid (containing only half of a full

The Genetics of Parenthood Abstract: Why do people‚ even closely related people‚ look slightly different from each other? The reason for these differences in physical characteristics‚ or appearance‚ (called phenotype) is the different combination of genes (the genotype) possessed by each individual. All of your genes are segments of DNA located on your chromosomes. To illustrate the tremendous variety possible when you begin to combine genes‚ you and a classmate will establish the

RANELLE JANINE L. ASI BIO 120 S-5L EXERCISE 9. Genomic DNA Isolation & Exercise 10. Polymerase Chain Reaction (PCR) Cell and molecular biology is a science based on the various systems of a cell resulting to its regulation‚ maintenance and function. Many of these systems involve genetic information hence the study of the DNA is an essential part of this field. To able to analyze DNA‚ it must first be isolated and purified from its natural environment filled with biological molecules and compounds
