Repetitive Sequences in Plant Nuclear DNA:Types, Distribution, Evolution and Function

引用

Genomics, Proteomics & Bioinformatics 2014年第4期12卷 164-171页

作者： Shweta Mehrotra Vinod goyal Department of Botany University of Delhi

Repetitive DNA sequences are a major component of eukaryotic genomes and may account for up to 90% of the genome size. They can be divided into minisatellite, microsatellite and satellite sequences. Satellite DNA sequences are considered to be a liist-evolving component of eukaryotic genomes, comprising tandemly-arrayed, highly-repetitive and highly-conserved monomer sequences. The monomer unit of satellite DNA is 150M00 base pairs （bp） in length. Repetitive sequences may be species- or genus-specific, and may be centromeric or subtelomeric in nature. They exhibit cohesive and concerted evolution caused by molecular drive, leading to high sequence homogeneity. Repetitive sequences accumulate variations in sequence and copy number during evolution, hence they are important tools for taxonomic and phylogenetic studies, and are known as ＂tuning knobs＂ in the evolution. Therefore, knowledge of repetitive sequences assists our understanding of the organization, evolution and behavior of eukaryotic genomes. Repetitive sequences have cytoplasmic, cellular and developmental effects and play a role in chromosomal recombination. In the post-genomics era, with the introduction of next-generation sequencing tech- nology, it is possible to evaluate complex genomes for analyzing repetitive sequences and decipher- ing the yet unknown functional potential of repetitive sequences.

Surging footprints of mathematical modeling for prediction of transdermal permeability

引用

Asian Journal of Pharmaceutical Sciences 2017年第4期12卷 299-325页

作者： Neha goyal Purva Thatai Bharti Sapra Pharmaceutics Division Department of Pharmaceutical Sciences Punjabi University

In vivo skin permeation studies are considered gold standard but are difficult to perform and evaluate due to ethical issues and complexity of process involved. In recent past, a useful tool has been developed by combining the computational modeling and experimental data for expounding biological complexity. Modeling of percutaneous permeation studies provides an ethical and viable alternative to laboratory experimentation. Scientists are exploring complex models in magnificent details with advancement in computational power and technology. Mathematical models of skin permeability are highly relevant with respect to transdermal drug delivery, assessment of dermal exposure to industrial and environmental hazards as well as in developing fundamental understanding of biotransport *** review focuses on various mathematical models developed till now for the transdermal drug delivery along with their applications.
