Rotavirus infects mature endothelial cells at the tip of the villi‚ which are present in the lumen of the small intestine. Prior to infection‚ the VP4 spike protein was cleaved into VP5 * 75‚ the body of the spike protein‚ and VP8 *‚ the head of spike proteins‚ by proteolysis with trypsin-like proteases present in the small intestine 75. In the endoplasmic reticulum‚ a cascade of processes is little known‚ with the assembly of VP4 and VP7 on the double layer particle and the removal of the transient

Introductory Life Science INTRODUCTORY LIFE SCIENCE At our 3rd lecture‚ we want to discuss • The building blocks of biological organisms – Carbohydrates‚ proteins‚ lipids and nucleic acids • Cell structure and function – Cell membrane‚ ER‚ Golgi‚ cytoskeleton‚ nucleus – Plant cell vs. animal cell Simple Chemistry for Life Science • Each element consists of one kind of atom. – An atom is the smallest unit of matter that still retains the properties of an element. – An atom contains

Chapter Four DEFINITIONS nucleic acid – polymers specialized for the storage‚ transmission between generations‚ and use of genetic information. There are two types‚ DNA and RNA nucleotides – monomers that compose nucleic acid‚ consist of a pentose sugar‚ a phosphate group‚ and a nitrogen containing base. DNA - – a macromolecule that encodes hereditary information and passes if from generation to generation. RNA and the bonds that stabilize them Purine - one of two chemical forms

move on to another organelle. What’s that system of membranes that I’m thinking of? Oh yea‚ the endoplasmic reticulum. Its job is to transport proteins and other materials. It’s made of rough proteins and other smooth materials. The Golgi apparatus what a cool name is that? It’s made up of things like membrane vesicles and sacks That store package proteins which are sent out of the cell Through vesicles that travel to organelles that need help. Now we’re at the lysosome‚ what does

is needed (carry proteins). Smooth Endoplasmic Reticulum- another industrial site which creates packages to send and communicate with other cities (steroids). Mitochondria- the electricity generator which creates energy for the city (ATP). Golgi Apparatus- the postal system of the city‚ collecting‚ processing and transporting (molecules) around and out of the city. Chloroplasts- the food manufacturing plant in a city! Plasmodesma- roads connecting the cities along which communication can occur

and genes is passed from parents to offspring in the family. 3. Nucleolus is like WATER PIPES ... Nucleolus produce proteins which are very important to the cell just like the water pipes produce water that is very important to the house. 4. Golgi apparatus is like a MAIL BOX ... Just like the mail box it processes and packages proteins for delivery to other organelles in the cell after they have been synthesized. 5. Endoplasmic Reticulum is like the KITCHEN ... where we made food and deliver it
