what determines the structure and function of a protein?
433376
Proteins are linear polymers built of monomer units called amino acids. ... The function of a protein is directly dependent on its threedimensional structure (Figure 3.1). Remarkably, proteins spontaneously fold up into three-dimensional structures that are determined by the sequence of amino acids in the protein polymer.

Describe the structure and function of DNA. FUNCTION: Holds genetic code/info/ genes and instructions for making proteins. What is the process of DNA replication? The double Helix unzips and new nitrogen bases are added to create a new strand of DNA to create a new cell.

Proteins are fundamental structural and functional elements within every cell of the body and are involved in a wide range of metabolic interactions. All cells and tissues contain protein, therefore protein is essential for growth and repair and the maintenance of good health.

A "structural" protein is usually something that provides scaffolding or something that give the cell or one of it's organelles shape. A "functional" protein is usually something like an enzyme, a protein that catalyzes a reaction of some kind. Examples of functional proteins are immunoglobulins and avidin.

Answer and Explanation: The relationship between DNA and protein is that DNA has the code, or instructions, for making protein. DNA is the genetic material of the cell.

Which statement best describes the relationship between cells, DNA, and proteins? (1) Cells contain DNA that controls the production of proteins. (2) DNA is composed of proteins that carry coded information for how cells function. (3) Proteins are used to produce cells that link amino acids together into DNA.

Structural genes are genes that code for proteins in the body needed for structure or function. Proteins are the building blocks of our cells. They create physical structures inside cells like the cytoskeleton, which gives our cells shape and support. Proteins also do important jobs inside the cell.

The Three-Dimensional Structure of Biological Macromolecules Determines How They Function. It is the three-dimensional shape of proteins and nucleic acids that endows them with their biological activities.

The four levels of protein structure are primary, secondary, tertiary, and quaternary. It is helpful to understand the nature and function of each level of protein structure in order to fully understand how a protein works. By Tracy Kovach.

DNA contains the genetic information of all living organisms. Proteins are large molecules made up by 20 small molecules called amino acids. All living organisms have the same 20 amino acids, but they are arranged in different ways and this determines the different function for each protein.

['Specific activity = total units of desired protein / mg of total protein.', 'Purification = final specific activity / initial specific activity.', 'Yield (%) = (final total units / initial total units) x 100.']

['Each amino acid contains a central C atom, an amino group (NH2), a carboxyl group (COOH), and a specific R group.', 'The R group determines the characteristics (size, polarity, and pH) for each type of amino acid.']

The relationship between the primary and tertiary structure of a protein is the both have a sequence of amino acids in a polypeptide chain. The sequence of amino acids in a primary structure determines its three-dimensional shape.

The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below).

In turn, proteins account for more mass than any other component of living organisms (with the exception of water), and proteins perform virtually every function of a cell. The process of translation, or protein synthesis, involves the decoding of an mRNA message into a polypeptide product.

By definition, the primary structure of a protein is the linear sequence of amino acids. Together, this linear sequence is referred to as a polypeptide chain. ... They can read the mRNA sequence and create a protein (polypeptide) from individual amino acids. This process is called translation.

Which level of protein structure do the α helix and the β pleated sheet represent? The tertiary structure of a protein is the: a) organization of a polypeptide chain into an α helix or β pleated sheet. b) bonding together of several polypeptide chains by weak bonds.
