Introduction
The Human Genome Project (HGP) stands as one of the most monumental scientific undertakings in history.Launched in 1990, this ambitious international endeavor aimed to map and sequence the entire human genome, comprising approximately 3 billion base pairs.The project's primary objective was to unravel the genetic blueprint of humanity, providing a comprehensive understanding of our genetic makeup.The HGP was not only a scientific milestone but also held immense promise for advancing medical research, personalized medicine, and understanding the genetic basis of various diseases [1].
Over the course of thirteen years, through collaborative efforts involving researchers from around the globe, the Human Genome Project was successfully completed in 2003.The significance of this achievement cannot be overstated, as it opened the floodgates to an unprecedented era of genomic exploration and analysis.The knowledge acquired from the HGP has transformed how we perceive human biology, evolution, and the genetic underpinnings of health and disease [2][3].

Explosion of Genomic Data and the Need for Advanced Analysis Techniques:
The successful completion of the Human Genome Project marked the beginning of a new era in genomics.Since then, advances in DNA sequencing technology have led to an exponential increase in genomic data generation.The cost of sequencing a genome has plummeted dramatically, making it more accessible to researchers, clinicians, and even consumers through direct-to-consumer genetic testing services.This explosion of genomic data has resulted in an overwhelming amount of genetic information that necessitates sophisticated analysis techniques to extract meaningful insights.Traditional methods of manual analysis are no longer sufficient, given the sheer volume and complexity of genomic data.Consequently, the integration of advanced computational tools and machine learning techniques has become essential to navigate this genomic data deluge effectively.Machine learning, a subset of artificial intelligence, has emerged as a transformative force in genomics research.Its ability to analyze vast datasets, identify patterns, and make predictions based on learned patterns makes it well-suited for genomic analysis.Machine learning algorithms can uncover hidden associations between genetic variations and diseases, accelerate drug discovery processes, and aid in personalized medicine initiatives [4] [5].

Human Genome Structure
The human genome is the complete set of genetic information encoded within the DNA of human cells.It contains all the genetic instructions required to develop, function, and sustain a human being.The structure of the human genome is organized in a highly coordinated and intricate manner [6].Here's an overview of the human genome structure.

DNA Molecule:
The human genome is primarily composed of DNA (deoxyribonucleic acid).DNA is a double-stranded helix, resembling a twisted ladder or a spiral staircase.Each DNA strand is made up of four nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T).The sequence of these bases along the DNA strands carries the genetic code.

Chromosomes:
The human genome is distributed across 23 pairs of chromosomes (22 pairs of autosomes and 1 pair of sex chromosomes).Chromosomes are thread-like structures made up of tightly coiled DNA and associated proteins.They are located in the cell nucleus.Each chromosome contains many genes, which are specific regions of DNA that code for proteins or functional RNA molecules [7].

Genes:
Genes are the functional units of the human genome.They are specific sequences of DNA that carry the instructions for producing proteins or functional RNA molecules.Proteins are essential for the structure, function, and regulation of cells, tissues, and organs.Some genes are involved in regulating other genes or have non-coding functions, such as regulatory elements or non-coding RNAs [8] [9].

Non-Coding DNA:
While genes make up a relatively small portion of the human genome (about 1-2%), the majority of the genome consists of non-coding DNA.Non-coding DNA does not directly code for proteins but plays critical roles in gene regulation, chromosome structure, and other cellular processes.

Introns and Exons:
Within genes, there are regions called exons that code for proteins and regions called introns that do not.Pre-mRNA, the initial RNA transcript of a gene, contains both exons and introns.During RNA processing, introns are spliced out, and exons are joined together to form mature mRNA, which then serves as a template for protein synthesis.

Repetitive Elements:
The human genome contains repetitive DNA elements, which are sequences that occur multiple times throughout the genome.These repetitive elements play various roles, such as stabilizing chromosome structure, regulating gene expression, and contributing to genomic evolution.

Telomeres and Centromeres:
At the ends of each chromosome are telomeres, which protect the chromosomes from degradation and fusion with other chromosomes.Centromeres are specialized regions within chromosomes that play a role in the proper segregation of chromosomes during cell division.

Genome Organization:
The human genome is organized into functional units, including topologically associated domains (TADs) and chromatin loops.These structures help regulate gene expression and ensure proper interactions between distant genomic regions.
