Abstract

ABSTRACT: RNA is the second major form of nucleic acid in human cells that play intermediary role between DNA and functional protein. Several classes of RNA's are found in cells, each with distinct function. Understanding of storage and utilization of a cell's genetic information is based on the structure of RNA. Many experimental results have shown that RNA plays a greater role in the cells. RNA sequences contains signals at the structure level can be exploited to detect functional motifs common to all or a portion of those sequence. Different types of analysis of a structure can provide functional information in different degrees of detail. In this paper various types of RNA secondary structure representation has been discussed and in which appropriate structure has been adopted for probabilistic approach that shows un-ambiguity.
