Requirements to become an official Canadian border?
I read all the requirements to become an officer of the border and saying that you should be enrolled full time in an accredited post secondary education. I just found out that St. Clair College, offer a course Chatnam Border Services Canada. Does anyone know if this school is accredited by the CBSA?
Contact the Community College and ask them. It makes sense that the university structure the course to the employment needs of the CBSA standards, right? Jim B. Toronto.

What option should i choose for college?
Hey guys, I'm almost finishing my GCSE's from high school and need to know what i must choose other options besides doing a Media Course. I have two ideas .. Music technology – I chose this because I simply love music and I was trying to be part of the music business when I'm more. The problem is that i cannot sing and do music GCSE so I do not know what I expected. Travel and Tourism – I chose this because I want to travel the world when I'm n the experience of other ancient cultures. I'm just sure if I could do a good race this because Being an air hostess does sound really appealing. Right? : S Any advice would be helpful:)
Travel and tourism of this is much better and many so are children in music now that u probably will not find any work that has to do w / it

Definitions and examples of the four levels of protein structure (primary, secondary, tertiary, quaternary)?
I need a simple definition and example of each. My Chem book I left school and am having difficulty finding the information because my internet keeps freezing. Help?!
• Primary structure refers to the linear sequence of amino acids that make up the polypeptide chain. This sequence is determined by the genetic code the sequence of nucleotide bases in DNA. The bond between two amino acids is a peptide bond. This link is formed by the elimination of a molecule H20 from two different amino acids forming a dipeptide. The amino acid sequence determines the position of different R groups in relation to each other. This position, which determines the way the protein folds and the final structure of the molecule. • The secondary structure of protein molecules refers to the formation of a regular pattern of twists or turns of the polypeptide chain. The regularity is due to the formation of hydrogen bonds between atoms of the amino acid backbone of the polypeptide chain. The two most common types of secondary structure called the alpha helix and beta pleated sheet. • Structure Tertiary refers to the three-dimensional globular structure formed by bending and twisting of the polypeptide chain. This process often means that the linear sequence of amino acids folds into a compact globular structure. The folding of the polypeptide chain is stabilized by multiple weak noncovalent interactions. These interactions are: ◦ The hydrogen bonds that form when a hydrogen atom is shared by two other atoms. ◦ electrostatic interactions that occur between charged amino acid side chains. Electrostatic interactions are attractions between positive and negative sites in macromolecules. ◦ hydrophobic interactions: During folding of the polypeptide chain, amino acids with a polar (water soluble) of the side chain are often found on the surface of the molecule, while that amino acids with nonpolar (water insoluble) side chain are buried inside. This means that the folded protein is soluble in water or aqueous solutions. Covalent bonds may also contribute to the tertiary structure. The amino acid cysteine, has an SH group as part of their group R and therefore, the disulfide bond (SS) can be formed with an adjacent cysteine. For example, insulin has two polypeptide chains that are linked by two disulfide bonds. • Quaternary structure refers to the fact that some proteins contain more than one polypeptide chain, adding an additional level of structural organization: the association of chains polypeptide. Each polypeptide chain protein is a subunit call. The subunits may be the same or different polypeptide chain. For example, beta-galactosidase enzyme is a tetramer, that is, which is composed of four subunits, and in this case, the subunits are identical – each polypeptide chain has the same amino acid sequence. Hemoglobin, a protein that transports oxygen in the blood, but also a tetramer composed of two polypeptide chains of a type (141 amino acids) and two other (146 amino acids). In chemical shorthand, this is known as a2ß2. For some proteins, quaternary structure is required for full activity (Function) of the protein
