What can happen if there is one wrong amino acid in a protein?
I feel like there are conflicting answers to this, probably because both play a role...tertiary structure is the actual 3-D structure, which dictates how the protein interacts on a molecular level, but primary structure ultimately determines tertiary...a recent practice question said primary structure, but I've seen tertiary as the answer before...Does anyone have a clear answer/reasoning for that answer?? interesting question. what happens if you change an important catalytic residue but maintain tertiary structure? no function. what if you denature something and it loses shape? no function. both are right. a question like this on the MCAT would definitely be more explicit, examples: it is found that a patient has a single amino acid mutation resulting in the change in activity of phosphofructokinase. this mutation most directly affects? -answer: primary structure, its a single amino acid mutation, the rest of the protein is probably the same. urea, a denaturing agent and byproduct of amino acid metabolism is found abnormally in other parts of the body. enzymes in this part of the body are unable to function properly most likely due to a change in: -tertiary structure. overall shape has changed.
Body structures that don't seem to have a function?
the appendix has no function There was an article on the internet recently that said that scientists think that the function of the appendix is that it stores bacteria so that if one's system is cleared of all "good" bacteria, the appendix can then start a new supply of those necessary bacteria. If this is true, then the appendix DOES have a function.
What is the effect of temperature on protein shape and give an example?
In most cases, extremes of temperature denature (alter the 3D structure of) proteins. In biological systems that denaturing temperature may be fairly mild. Another term for protein denaturing is coagulation which is what happens to the proteins of a boiled egg.
When a protein loses its natural shape it is said to be what?
When a protein has lost its 3D structure it becomes polypeptide chain with some secondary structure elements are they may simply degraded to it primary structure which is polypeptide chain.3D structure is a native structure of protein molecule where it can have the correct folding stabilized by its intra and inter molecular interactions among its residues.Proteins can loose its structure when they are exposed to a denaturing condition which is change in buffer environment such as pH, temperature,ion salts, metals and detergents such as SDS can unravel the proteins structure. Reducing agents such as DTT or 2-mercaptoethanol or often used with heat (95 degrees) to denature the protein completely while resolving them on the gel.
Identify two of the three assumptions in the Cell Theory?
1. Cells are the basic unit of structure in all living things.2. Cells carry on all life processes.even though you only said two...3. Cells are produced by other living cells.
What is a structure in similar organisms that once had a function but is no longer used today is said to be?
vestigial
What does it mean when dinosaurs have homologous structure?
Two samples are said to homologous, in this context, when they are both very similar in structure and shape and more than likely function.
What is the definition of Conscientious?
Influenced by conscience; governed by a strict regard to the dictates of conscience, or by the known or supposed rules of right and wrong; -- said of a person., Characterized by a regard to conscience; conformed to the dictates of conscience; -- said of actions.
What structure connets the right and left cerelobarl himispheres?
Within the human brain, the structure that connects the right and left cerebral hemispheres is called the corpus collosum. There is said to be strong bilateral symmetry in both function and structure of the two hemispheres.
Describe in brief your current your current position reporting structure responsibilities under the finance function finance team structure?
To know how much training will be needed a person will need to know what the exact job is. Since there is not anything said about what the exact job is a person will no know the answer.
Function of the government?
If you are referring to the jobs of the three branches, the legislative branch makes laws, the judicial branch interprets said laws, and the executive branch enforces them.
What is the meaning of conscientious?
Influenced by conscience; governed by a strict regard to the dictates of conscience, or by the known or supposed rules of right and wrong; -- said of a person., Characterized by a regard to conscience; conformed to the dictates of conscience; -- said of actions.
