What is the three dimensional Structure of Keratin?
Keratin is a protein, so it has both a primary and secondary structure. In fact, all proteins have a primary and secondary structure, along with a tertiary and quaternary structure. There are many different ways proteins can be structured and shaped, so biochemists divide proteins into 4 separate parts or structures.
What are the links between DNA genes chromosomes and proteins?
Chromosomes are long strands of DNA which are held together by proteins.
What chemical links the worlds of DNA and proteins?
The chemical link between DNA and proteins is messenger RNA (mRNA). mRNA carries the genetic information from DNA to the ribosomes, where proteins are synthesized by a process called translation. This enables the interaction between the genetic code in DNA and the amino acid sequence in proteins.
What is one reason that some tissues become stiffer as they age?
when glucose is haphazardly added to proteins inside and outside cells, forming irreversible cross-links between adjacent protein molecules. The more cross-links the stiffer the tissues get with the lack of elasticity.
What does functional protein look like?
Briefly, proteins (polypeptides) look like amino acids chained together; look at the link below for a detailed description of proteins' appearance. Proteins have a couple different levels of structure including the primary, secondary, tertiary, and quaternary. At the primary structure, proteins are just linked amino acids through peptide bonds. Amino acids have the same general structure with a variable R-group. At the secondary structure, the chemical properties of the amino acids form hydrogen bonds with each other and give shape to the protein. The two general shapes of proteins at the secondary structure: alpha helices and beta-pleated sheets. An alpha helix looks like a spiral while a beta-pleated sheet looks like stairs. See the related links below for images. The tertiary structure is characterized by further interactions by the R-groups on the amino acids. Various bonds can distort the alpha helix or beta-pleated sheet such as ionic bonds, disulfide bridges, covalent bonds, and hydrophobic interactions. The complete protein is seen at the quaternary structure, which is the arrangements of polypeptides into a single macromolecule.
What is the structure inside the cell that links amino acids to perform proteins?
Endoplasmic reticulum
What is a temporary structure made on the outside of a building?
A temporary structure made on the outside of a building is called scaffolding. Scaffolding is used to provide support for workers and materials during construction, maintenance, or repair work on the building.

What is is cell membrane?
The membrane that surrounds the cytoplasm of a cell; it is also called the plasma membrane or, in a more general sense, a unit membrane.

How do disulfide bonds contribute to the structural integrity of keratin proteins?
Disulfide bonds in keratin proteins help to strengthen and stabilize the protein structure by forming cross-links between different protein chains. This contributes to the overall structural integrity of keratin, making it more resistant to breaking or damage.

Functional group links amino acids together to form proteins?
Peptide bonds.
What links together to make proteins?
They are the amino acids. Peptide bonds hold them together
