Proteins are created
from amino acids in the ribosomes of cells by RNA strands cooperating
with enzymes (other proteins) that assemble and construct the sequence
of separate amino acid molecules on a chain
of amino acids.
Once
assembled, the chains of amino acids are
folded appropriately (by another enzyme) into the precise
shape of the new protein. The order of the
amino acids dictates the specific protein to be built. This partnership
among proteins and nucleic acids in the cells and on the sub-cellular
level causes me to suggest the term "genosystem" when describing
the complexity of the gene's many functions.
Of
these vital functions, the retention of essential protein construction
must be accompanied by conserving the capacity for generating variability.
The
term "genosystem" is used to suggest the complexity of feedback
response systems and the depth of cooperative functions among enzymes,
RNA and the cells organelles (such as ribsomes and golgi bodies) that
work in tandem or in a series of preceise maneuvers that regulate the
cell's internal conditions of existence and communication with adjacent
cells in the tissues of multicellular creatures.

The hemoglobin protein [ depicted
above ] that oxygenates (a structure in the protein brings oxyygen to the brain and organs because it binds to molecular oxygen) vertebrate
red blood cells is composed of
complex molecules and alpha-helices. Shown above, the protein structure can attach oxygen
to iron atoms held, in suspension at four areas within this large molecule's precisely folded structure.
It is the shape of the protein that allows molecules
within the structure to function and in that manner to assist in the regulation
of cells. In this sense the protein molecules are partners with organelles
that make up sub-cellular existence.

Proteins
are built of Amino acids, by
the action of RNA and other proteins. There are only twenty-two amino
acids, but they are arranged in a different sequence in the making of over 100,000
proteins. By arranged in a certain order, scientists mean that the sequence of nitrogen
base pairs on the DNA or RNA can be translated into one of the 22
amino acids listed in the chart below. WHen arranged in sequence the amino acids create
a precise order in a chain of amino acids. This chain forms the basis
of a much larger protein which is then folded into a shape that can function in a cell.
U or Uracil in RNA is the equivalent
of T or Thymine in the DNA molecule's nitrogen
bases.
Amino
Acids are built of sequences of nucleic acid, called base pairs. The molecules that make up these base pairs are represented in this diagram by blue spheres:

Sequenced
base pairs of nucleic acid code for
amino acids, such that three nitrogen
base pair sequences (trios) match precise amino acidsand no others.
cytosine to guanine
adenine to thymine
Base
pairs refer to five nitrogen bases found in the chromatin material of
cells. In eukaryotic organisms the chromosomes are in the pouch of the
cell's nucleus. The nitrogen base (N-base) pairs
are arranged by cellular proteins in a sequence that can be translated
by other proteins into an appropriate amino acid, a signal to start
to stop transcription, or prion.
These
nitrogen base pairs contain to the following molecular components of
DNA sequences:

Nitrogen Bases
Adenine and Thymine
Nitrogen Bases
Guanine and Cytosine
The (macro) molecules of DNA and RNA are built up of millions of nitogen base pairs drawn above to identify
their atomic elements and hydrogen bonds.
