Segmentation of DNA sequences into twostate regions and melting fork regions.
The accurate prediction and characterization of DNA melting domains by computational tools could facilitate a broad range of biological applications. However, no algorithm for melting domain prediction has been available until now. The main challenges include the difficulty of mathematically mapping a qualitative description of DNA melting domains to quantitative statistical mechanics models, a...
متن کاملSegmentation into Fuzzy Regions Using Topographic Distance
This paper exposes an algorithm which leads to a fuzzy segmentation. This algorithm performs, as in the watershed method, a progressive flood of the gradient image from pixels of lowest gradients. It uses a new distance, called topographic distance. Any local minimum of the gradient norm image constitutes a seed for the region growing, avoiding the use of a marker image. These seeds constitute ...
متن کاملLocalization of low-melting regions in phage T7 DNA.
Specific fragmentation of T7 DNA at glyoxal-fixed denatured regions by the S1 endonuclease followed by restriction analysis made it possible to localize four low-melting regions in phage T7 DNA. These regions have the following coordinates:0.5-1.2;14.8+/-0.3;46.3+/-0.5; 98.4+/-0.3 (in T7 DNA length units). The location of the low-melting regions was refined by means of electron-microscopic dena...
متن کاملa fast algorithm for exonic regions prediction in dna sequences
the main purpose of this paper is to introduce afast method for gene prediction in dna sequences based on the period-3 property in exons. first, the symbolic dna sequences are converted to digital signal using the eiip method. then, to reduce the effect of background noise in the period-3 spectrum, we use the discrete wavelet transform (dwt) at three levels and apply it on the input digital sig...
متن کاملLocating regions of differential variability in DNA and protein sequences.
In the comparison of DNA and protein sequences between species or between paralogues or among individuals within a species or population, there is often some indication that different regions of the sequence are divergent or polymorphic to different degrees, indicating differential constraint or diversifying selection operating in different regions of the sequence. The problem is to test statis...
