What must be done to a polypeptide chain to make it a functioning protein?
Wiki User
∙ 12y ago
A protein becomes functional only when it folds itself into a three dimensional form or tertiary structure.
More information -
All amino acids have the same basic structure - an amino group, a carboxyl group and a hydrogen atom but they differ due to the presence of the side chain. The sequence of amino acids in a protein determines it's primary structure

∙ 9y agoThere is a few things that causes polypeptide chain to fold into functional proteins. The things that causes this are chemical properties and its affinities for other amino acids.

If proteins were rigid why would they make poor reseptors?
Proteins have a lot of roles in the body. Proteins functioning as receptors have to bind securely to another molecule (usually another protein). Protein structure is defined by the amino acids that make up the protein (primary structure), then two levels of the folding the protein undergoes to get its final shape (ending with tertiary structure). The tertiary structure of protein receptors have to be very complicated to be unique enough to be effective receptors. Therefore, tight binding between the two proteins often requires some amount of rearrangement before the two molecules 'lock' into place. The 'locking' is also done at many locations and doesn't happen all at once. If the molecules were rigid they would have to 'lock' all at once, and spacial rearrangement would be harder.
What does tethered mean?
Tether means a rope, chain, or similar restraint for holding something (like an animal) in place, allowing a short radius in which it can move about. Like a dog chained up. So tethered means this has been done.

What structure describes the alpha-helices and beta-sheets that are formed by hydrogen bonding vetween backbone atoms located near each other in the polypeptide chain?
This bonding is done in the secondary structure of the protein.
How are amino acids transfered to the ribosome into a growing polypeptide chain?
The ribosome uses tRNA that matches the current codon (triplet) on the mRNA to append an amino acid to the polypeptide chain. This is done for each triplet on the mRNA, while the ribosome moves towards the 3' end of the mRNA.
Why do cells nedd ribosomes?
Ribosomes are used in protein synthesis. It's the site where the nucleotide code of the mRNA strand is read, in sets of three, and the matching tRNA, each carrying a specific amino acid, assemble the polypeptide chain. When the chain is done, the ribosome detaches from it and attaches to another mRNA to begin the process all over again.
Difference between gene therapy and protein therapy?
at the gene level gene therapy is done and at the the protein level protein therapy is done
What is the role of tRNA in translation?
tRNA is used to carry the 20 different amino acids dissolved in the cytoplasm to the ribosomes to help build the polypeptide chain for proteins to be synthesized. Each tRNA molecule attaches to one type of amino acid.
Are there timing chain guides in a 1993 ford escort?
No, there are no guides and the timing is done with a belt, not a chain.
