the vacuole‚ it’s very large. It stores water and food and it’s in charge Of foods and wastes. It’s enclosed in the cell. Now let’s 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

Vacuoles | Both | Plants have a large central vacuole. Animal cells have smaller ones. | Used to store nutrients and water in the cell. | Vesicles | Both | Similar structure to a vacuole. | Transports materials throughout a cell. | Rough Endoplasmic Reticulum (rER) | Both | Network of membrane tubes which branch from the nuclear envelope. Covered in ribosomes. More prominent in cells that make large amounts to be exported from the cell‚ or inserted into the cell membrane. | Makes proteins. |

RPL12 silencing‚ and SiRNA-mediated silencing of ribosomal stalk proteins‚ among other things. RPL12 knockdown confirmed the relevance of RPL12 silencing on correcting misprocessing of ΔF508-CFTR and increased the ΔF508-CFTR efficiency at the Endoplasmic Reticulum. RPL12 silencing in combination with VX-809‚ a corrector drug‚ increased the functional expression of ΔF508-CFTR in “immortalized and primary human bronchial epithelia.” And last but not least‚ SiRNA-mediated silencing of ribosomal stalk proteins

The Central Nervous System (CNS) The CNS is responsible for coordinating and controlling the activities of our body such us control of the muscles and the mental activity. The main organs of the CNS is the brain‚ spinal cord‚ and nerves. These organs mostly consist of Nervous Tissues. http://www.nlm.nih.gov/medlineplus/ency/images/ency/fullsize/19588.jpg Nervous Tissues Nervous tissues are made up of two main types of cells: nerve cells/neurons and neuroglia.

making sure of target specificity. Once the peptide containing the signal sequence has bound to the respective receptor‚ the peptide is transferred through the lipid bilayer through the translocation channel. For example in case of 1. Endoplasmic reticulum- ER signal sequence is about 16- to 30- residues in length and they are located on the N-terminal of the protein. Two important components in targeting the protein to the ER membrane include signal-recognition particle (SRP) and its receptor
