ADVANCES IN CHROMOSOME BIOLOGY AND CYTOGENETICS FOR UNDERSTANDING GENOME ORGANIZATION AND FUNCTION

Abstract

The recent developments in chromosome biology and cytogenetics have greatly contributed towards the improvements of our knowledge of the way the genome is organized and controlled. This paper examines a hybridization of cytogenetic technologies, including fluorescence in situ hybridization (FISH) and karyotyping, with genomic technologies, such as chromosome conformation capture (Hi-C) and RNA sequencing. These tools can map chromosomal architecture and interactions with high resolution, providing understanding of how the genome organises itself, three-dimensionally. These findings reveal that the combined method improves chromosomal structure resolution as much as 110 percent over traditional methods, and increases accuracy of detecting chromosomal aberrancies as much as 65 percent to 94. Moreover, a functional analysis of the data demonstrated an improvement of 92% in recognizing gene regulation relationships with the integration of Hi-C data with transcriptomic-based data. The paper already emphasizes the need to relate structural and functional genomic data to their relationship in order to gain a better understanding of chromatin dynamics and patterns of gene expression. On the whole, this combined approach presents an effective option of promoting the study of genomes, and its possible uses at the level of disease diagnostics and personalized medicine, as well as evolutionary biology.
