The sequence of nitrogenous bases (A, T, G and C) forms a code for the sequence of amino acids in a protein.
The code is a triplet code. This means that three bases code for one amino acid.
So, the order of the bases in a gene determines the order of the amino acids in a protein.

How does the sequence of DNA affect the function of a protein?
The sequence of nucleotides in DNA molecule is equivalent and is closely related to an amino acid sequence in the protein molecule. If for any reason the sequence of DNA nucleotides changes it will be reflected in amino acid sequence in the protein. Moreover, the correct sequence of amino acid in the protein will form the correct three-dimensional structure, or tertiary structure, that will confer the biological activity to protein. If a wrong amino acid is translated from a mutated gene in the DNA could change the spatial structure of the protein and therefore modify or erase its biological function.
Which level of protein structure is most related to specificity?
The tertiary structure of a protein is most related to specificity. This level of structure is where the unique three-dimensional arrangement of amino acids within a protein allows it to interact specifically with other molecules, such as enzymes with their substrates.
What is the four levels of proteins?
Proteins have primary structure, which is their amino acid sequence, secondary structure, which is either the alpha helix or the beta pleated sheet, tertiary structure, the protein's geometric shape, and quaternary structure, the arrangement of multiple protein subunits.
What is distinctive about primary vs secondary protein structure?
The primary structure of a protein is just an amino acid string; a polypeptide. The secondary structure of a protein is the hydrogen bonding of the side chains that form the polypeptide chain into alpha helices and beta sheets.
How does the structure of macromolecules such as proteins act as an index of relatedness between species?
Organic molecules that just so happen to weigh more than 100,000 daltons, are from that point on then referred to as macromolecules which is related between the species.

How are proteins related to the coded hereditary message on DNA?
The sequence of a gene's DNA leads to the synthesis of an RNA molecule. The RNA is the instruction manual for a Ribosome to make a specific amino acid sequence. When the amino acids are put together, the protein is made. So from this process, you can see that a protein's structure depends on the DNA code.

How does the variation in protein reflect changes in a species DNA?
As new species evolve they build up differences in the DNA from related species, as a result of mutation and selection. The role of DNA is to encode the structure of proteins. The DNA code defines the sequence of amino acids in each protein. So if the sequence of bases in the DNA changes, the sequence of amino acids in the proteins can also change as a result. If we compare closely related species there should be fewer differences in their DNA and so fewer differences in their proteins than between distantly related species. By comparing amino acid sequences we can therefore estimate how closely or distantly related two species are to each other. (see related links)

What is secret pseudo protein code?
Secret pseudo protein code (SPPC) is a method used to conceal the true amino acid sequence of a protein by encoding it using a different set of codons. This can be useful for protecting intellectual property related to protein sequences or for creating synthetic proteins with specific properties without revealing the exact amino acid sequence.
What determines the different shapes and functions of proteins?
A protein's structure is determined by:- the amino acid sequences of its polypeptide chains;- hydrogen bonds between amino acids in polypeptides;- other bonds (e.g. hydrophobic interactions, disulphide bridges) between side chains in the polypeptides; and- the arrangement of polypeptides (in a protein that contains more than one polypeptide)Scientists have mapped the structures of several proteins; however, scientists are still unsure as to how proteins actually form their final structures.The function of a protein is directly related to its structure. For example, a protein that fights a certain bacteria might have a shape that allows it to bind to the bacteria and then destroy it.
How is Protein Structure related to its function?
Protein structure is directly related to its function because the three-dimensional shape of a protein determines its ability to interact with other molecules. This shape allows the protein to perform specific functions, such as enzymatic reactions, signal transduction, or structural support. Any changes in the protein structure can alter its function and potentially lead to dysfunction or disease.
What is a helical protein?
"Helical" refers to its structure -- a helix (a spiral). See the related link below for an image.
