A normal protein can be composed of about 10000 amino-acid residues, that is something like 100000 atoms, but large proteins exist composed by more than 500000 atoms. All these atoms are not randomly distributed, but forms a complex and ordered structure, called the protein secondary and tertiary structure.
Just to make the situation more complex, several proteins sometimes join together to form protein complexes, like the heart Troponin complex.
As all biomolecules proteins react with other molecules in specific sites, called active sites for the considered reactant. Naturally different active sites exist, for different molecules with which the protein can react.
The possibility of a protein to react with a certain molecule depends not only from the presence of a suitable active site that binds with the considered molecule, but also from the protein shape, the so called steric factor. For example, if the protein shape enclosed the active site withing a sort of shell, that renders impossible to the other molecule to reach it, the reaction cannot happen even in the presence of a suitable active site.
last, but not least, reaction is possible frequently only in suitable environmental conditions like pH, reagents concentrations, presence of enzymatic catalysis and so on.
Such a complexity is very difficult to manage without the help of a computer that allows the huge number of possible situations to be managed.
Computer algorithm and software are being developed to handle tedious and carefully calculated experimental data.
Using computer models to study complicated events enables us to make a three dimensional structure of any event.
Computer models can analyze and process data at a stunning speed and accurate results are obtained.
Scientists use models in DNA because it helps them visualize what a DNA stem looks like.
better drawing and explaination of the structure
the computer is important for the new modern world they help as .. to comunicate ..
is that mean a computer is so important
because protein's are 3D!!!!
I really don't know
Plants need protein for their: growth formation of green leaf root development
because protein needs our body to make a move..

pepsinogens when pumped into the stomach and exposed to an acid environment form pepsin. pepsin is a protease breaking proteins down into amino acids.
Transcription of the DNA into messenger RNA (mRNA). mRNA contains the anti-codons for ribosomal binding, so the transfer RNA (tRNA) can add the corresponding amino acid. This part is known as translation.

the function of each protein is a consequence of its specific shape, which is lost when a protein becomes denatured.The shape of a protein determines its specific function within a cell. Denaturing a protein will alter its shape, thus it will no longer function.

Can you describe how the amino acid changes in the protein affects the function of the protein?
analysing the function of a particular protein is protein characterization.
The way that a polypeptide folds to form the protein determines the proteins function.
It is an arabidopsis plant with the AADL protein "turned off." Scientists insert a nucleotide into the gene sequence which stops the AADL gene from being able to function. The AADL gene tells a ribosome to make the AADL protein. With it being turned off, the AADL protein never gets made.
DNA sequences do not determine the function of any protein. DNA sequences determine the structure of the protein. That is particular amino acid sequence in protein only.
RNA manufactures protein
Proteins tend to have 3 or 4 structural levels, every protein has specific level, in which it can function. Denaturation brings protein back to the 1st structural level, so it can no longer function. For example, enzymes have the 4th structural level, then they can function. And when they are denaturated, they are brought back to the 1st level and cannot function.
Its function
The sequence of amino acids determines the specific function of a protein. The shape and structure of the protein determines where in the cell it can go.
