Prediction of Nucleosome Positioning Using Machine Learning Methods
8
2019
Nucleosome is the basic structure of chromatin in eukaryotic cells. The location of nucleosomes plays an important role in gene transcriptional regulation. Knowledge of the detailed organization of nucleosomes in the genome and the mechanisms of nucleosome positioning is crucial for understanding gene regulation and expression.

In recent years, a large number of works in the field of bioinformatics, physics and biology have been devoted to the study and prediction of nucleosome positioning in the genomes of various organisms based on many factors (frequency of nucleotide k-mers, geometric and physic-chemical properties of dinucleotides, analysis of primary DNA sequences with convolution neural networks).

This work is devoted to the study and prediction of the nucleosome positioning in the human genome based on the structural properties and parameters of the electrostatic potential and bendability of the DNA sequence using machine learning models. Using the constructed model the generalizing probabilistic profile of nucleosome positioning was constructed and comparison of predictions in different types of tissues was made.

Student Theses at HSE must be completed in accordance with the University Rules and regulations specified by each educational programme.

Summaries of all theses must be published and made freely available on the HSE website.

The full text of a thesis can be published in open access on the HSE website only if the authoring student (copyright holder) agrees, or, if the thesis was written by a team of students, if all the co-authors (copyright holders) agree. After a thesis is published on the HSE website, it obtains the status of an online publication.

Student theses are objects of copyright and their use is subject to limitations in accordance with the Russian Federation’s law on intellectual property.

In the event that a thesis is quoted or otherwise used, reference to the author’s name and the source of quotation is required.
