PACKAGING OF ORGANS = PRIMARY,SECONDARY AND TERTIARY STRUCTURE OR MOLECULES.

Biomolecular structure is the intricate folded, three-dimensional shape that is formed by a molecule of protein, DNA, or RNA, and that is important to its function. This useful distinction among scales is often expressed as a decomposition of molecular structure into four levels: primary, secondary, tertiary, and quaternary. The scaffold for this multiscale organization of the molecule arises at the secondary level, where the fundamental structural elements are the molecule's various hydrogen bonds. This leads to several recognizable domains of protein structure and nucleic acid structure, including such secondary-structure features as alpha helixes and beta sheets for proteins, and hairpin loops, bulges, and internal loops for nucleic acids.

The primary structure of a biopolymer is the exact specification of its atomic composition and the chemical bonds connecting those atoms (including stereochemistry). For a typical unbranched, un-crosslinked biopolymer (such as a molecule of a typical intracellular protein, or of DNA or RNA), the primary structure is equivalent to specifying the sequence of its monomeric subunits, such as peptides or nucleotides..

the primary structure of a protein is reported starting from the amino terminal (N) to the carboxyl terminal (C), while the primary structure of DNA or RNA molecule is reported from the 5′ end to the 3′ end.

The secondary structure is the pattern of hydrogen bonds in a biopolymer. These determine the general three-dimensional form of local segments of the biopolymers, but does not describe the global structure of specific atomic positions in three-dimensional space. secondary structure of protein is a TWO DIMENSIONAL(2D) OR PLANE STRUCTURE which includes alpha - helix and beta-strand or beta-sheets or beta-pleated structures.

3d structure starts(GLOBULAR - SPHERE OR CUBE) – The tertiary structure of a protein or any other macromolecule is its three-dimensional structure, as defined by the atomic coordinates.Proteins and nucleic acids fold into complex three-dimensional structures which result in the molecules' functions.

PACKAGING OF DNA(INFORMATION GOODS) In eukaryotes, nuclear chromosomes are packaged by proteins into a condensed structure called chromatin.This allows the very long DNA molecules to fit into the cell nucleus. (just to make sure that the information does not get overlapped on to each other because it would lead to agreat confusion they are wrapped around proteins called histone proteins) in to chromatin.
