DESCRIPTION:DNA is a biological polymer which basic function in the cell i
 s to encode the genetic material. DNA molecules can be considered to be a 
 mechanical structure on the nano-level. There are different approaches to 
 studding the mechanical properties of the DNA molecule (experimental\, the
 oretical modeling). A number of mechanical models of the DNA double helix 
 have been proposed so far. Different models are focusing on different aspe
 cts of the DNA molecule (biological\, physical and chemical processes in w
 hich DNA is involved). A number of models have been constructed to describ
 e different kinds of movements in a DNA molecule: asymmetric and symmetric
  motion\; movements of long and short segments\; twisting and stretching o
 f dsDNA\, twist-opening conditions. Some models have\, for example\, been 
 made for circular double-stranded DNA molecules in viral capsids. We are d
 iscussing here polymer models\, elastic rod models\, network models\, tors
 ional springs models\, soliton -existence supporting models and multi pend
 ulum/multi chain models\, emphasizing specifies of each model. Hedrih  (S
 tevanović) and Hedrih\, gave several mechanical models of double DNA. In 
 their models DNA is in a form of homogenous multi-chain/multi-pendulum sys
 tem which oscillatory signals can be considered trough a system with fixed
  and with free ends. The models differ in the way of coupling between the 
 material (mass) particles. They’re several types of these models: Model 
 with ideally elastic properties\, Model with hereditary properties and Fra
 ctional order model. \n\nhttps://indico.ipb.ac.rs/event/144/
