Document Summary
Cytoskeleton is made up of microtubules, microfilaments and intermediate filaments. Protein filaments allow cell to transport materials, intracellularly, change shape, interact mechanically with their environment and move within their environment. Microtubules are long, hollow proteins built from repeating structural units called tubulin dimers. A tubulin dimer is composed of alpha or beta tubulin. The plus end is built faster then the minus end. Eukaryotic flagella: highly specialized structures used for cell motility. Pythium ultimum: micro-organism and a common plant pathogens. Cycloheximide is a well-known inhibitors of protein synthesis located from the bacteria streptomyces griseus. It binds to the eukaryotic ribosome and blocks the elongation phase of translation (elongation factor 1,2) Binds to microtubules and interferes with cell division and intracellular transportation there inhibiting the growth. Chlamydomonas rheinhaedtii were grown the bold"s basal medium (bbm) Control culture is de-flagellated and treatment culture cycloheximide and de- flagellated. Count the cells and determine the portion that have flagella.
