Proteins have up to four levels of organic structure.
1.Primary structure - the linear arrangement of amino acids.
2. Secondary structure - areas of folding or coiling within a protein.
3. Tertiary structure - the final three dimensional structure of a protein.
4. Quaternary structure - non covalent associations that bind multiple polypeptides into a single larger protein. E.g. hemoglobin has four polymers, two alpha and two beta chains. They are non covalently bound to each other to form a single large protein - hemoglobin.
Data shows results of an experiment which was added to each peptide to culture the TRAP. Mutants of S. aureus and culture of the Agr. mutant of s. aureus.
Peptide 1 and three blocks Agr pathway
Peptide 2 blocks TRAP pathway
This is because the mutants are already blocked for one of the pathways.
Therefore it gives way to determine which pathway each peptide act on.
Answer:
photosynthesis is a process by which plants use sunlight,water,and carbon dioxide to create oxygen and energy in the form of sugar
Answer:
b, c, and f
Explanation:
Since it is type A it will have antigen A on it's surface and only antigen A it will contain anti-B antibodies as that's the incorrect protein. These anti-B antibodies will cause agglutination with blood type B
Specific proteins are made only at certain times in certain cells.
