In the context of the molecular life of organisms, genomics helps to understand how genetic information is encoded and how it is implemented at the molecular level, ensuring the vital activity and characteristics of each organism. In the structure of genomes, DNA sequences, the arrangement of genes, regulatory elements and other molecules that make up the genome are studied. Gene functions determine how genes encode proteins and other molecules, their role in metabolism, growth, development and interaction with the environment. Studying changes in the genomes of different species, which helps to understand the origin and adaptation of organisms. The use of modern sequencing, analytics and bioinformatics methods is important for the rapid and accurate study of the molecular basis of life. Molecular mechanisms help to uncover processes such as replication, transcription and translation that underlie the functioning of cells. Overall, informative genomics provides a deep understanding of the molecular basis of life, allowing us to trace how genetic information controls all aspects of the existence of organisms - from the simplest bacteria to complex multicellular creatures. Informative genomics is the foundation for maintaining the life of an organism at the molecular level, the development of biotechnology, genomic medicine, ecology and evolutionary research.

The informative nature of genomics allows not only to store and process huge amounts of data, but also to extract knowledge from them about the molecular mechanisms of life, evolution and interactions of organisms with the environment [1,2]. This is the foundation for the development of personalized medicine, biotechnology and systems biology.

Genomics studies the structure, function, evolution, and relationships of genes and genomes of organisms. It combines knowledge from molecular biology, genetics, bioinformatics, and other sciences to understand the full picture of genetic information and its role in the life of organisms.

5. Drug Development: Understanding the genetic basis of diseases helps to create targeted drugs that attack specific molecular targets. 

6. Genomic Diseases: These are inherited diseases caused by abnormalities in the number or structure of chromosomes, in particular, changes in the entire genomic set (for example, aneuploidy). These diseases occur as a result of errors in cell division, leading to an increase or decrease in the number of chromosome sets. The main types of genomic diseases: 

6.1. Trisomies - the presence of a third copy of one of the chromosomes: 

- Down syndrome (trisomy 21) is the most common genomic disease, characterized by mental retardation, characteristic facial features, heart defects and other disorders. 

- Edwards syndrome (trisomy 18) is a severe condition with multiple abnormalities, high mortality at an early age. 

- Patau syndrome (trisomy 13) - severe malformations, low survival. 

6.2. Tetraploidy and polyploidy - an increase in the full set of chromosomes: - Usually incompatible with life in humans, with the exception of some cases in the embryonic stage. 

6.3. Aneuploidy - the presence of an extra or missing chromosome: - For example, monosomy X (Turner syndrome) — in women, characterized by underdevelopment of sexual characteristics, short stature and other features. - Multifollicular syndromes and others. 

6.4 Causes: - Errors in meiosis or mitosis, leading to incorrect distribution of chromosomes. - The age of the parents (especially the age of the mother during pregnancy) increases the risk of such errors. 

6.5 Diagnostics and treatment: - Genetic counseling. 

- Karyotyping, molecular diagnostic methods.

It is important to understand that genomic diseases require a comprehensive approach to diagnostics, support and correction of patients' condition. In general, genomics is a powerful tool for revealing the causes of many diseases and developing effective methods for their prevention, diagnosis and treatment.

4.1 The process of transition of normal cell into malignant cell 

The process of transition of a normal cell into a malignant cell is a complex and multi-stage biological process, including sequential genetic and epigenetic changes. Below is a description of the main stages and mechanisms of this transformation: 

1. Genetic and epigenetic changes: 

- Mutations and chromosomal abnormalities: ** occurrence of point mutations, deletions, duplications, translocations, inversions leading to activation of oncogenes or inactivation of tumor suppressor genes. 

- Epigenetic changes: hyper- or hypomethylation of DNA, histone changes, which affect the expression of genes associated with the control of growth and proliferation. 

2. Activation of oncogenes and inactivation of suppressor genes: 

- Oncogenes: genes that stimulate cell growth and division (e.g., *RAS*, *MYC*, *EGFR*). Their activation leads to uncontrolled proliferation. 

- Suppressor genes: genes that suppress growth and prevent tumor transformation (e.g., *TP53*, *RB*). Their inactivation removes control over cell division. 

3. Changes in cell cycle regulation: 

- Dysregulation of cell cycle checkpoints, which leads to uncontrolled division. 

4. Formation of abnormal cellular characteristics: 

- Eutolyzation of apoptosis: decreased sensitivity to programmed cell death. –

 Migration and invasiveness: acquisition of the ability to penetrate into surrounding tissues and metastasize. - Angiogenesis: stimulation of the formation of new blood vessels to feed the tumor. 5. Mechanisms of resistance and survival: 

- Providing resistance to stresses such as hypoxia, nutrient deficiency, therapy. 

6. Mechanisms and factors involved in transformation: 

- Genetic instability: increased probability of new mutations. 

- Environmental influences: carcinogens, radiation, toxic substances, viruses. 

- Viral infections: e.g. human papillomavirus (HPV), hepatitis B and C viruses, which can integrate into the genome and activate oncogenes or inactivate suppressor genes. 

7. Summary model: 

- The process of cell transformation involves the accumulation of mutations, changes in gene regulation, activation of oncogenes and inactivation of suppressor genes, which leads to loss of control over growth, invasion and metastasis. This process is often multifactorial, and its gradual nature allows for early detection and potential interruption.

4.2 Molecular pathways and genes of malignant tumor formation

The formation of malignant tumors (cancer) is a complex multi-stage process that includes the activation of oncogenes and the inactivation of tumor suppressor genes. The main molecular pathways and genes involved in oncogenesis are listed below:

2. PI3K/AKT/mTOR pathway: 

- Genes: PIK3CA, AKT1-3, PTEN (inhibits the pathway), mTOR 

- Role: Controls cell growth, survival and metabolism. Activation promotes oncogenesis. 

3. Tumor suppressor genes (growth inhibition signals): 

- Genes: TP53, RB1, CDKN2A (p16INK4a, p14ARF), PTEN 

- Role: Provides control over division and prevents uncontrolled proliferation. Their inactivation leads to tumor development. 

4. Nuclear factors and the Wnt/β-catenin pathway: 

- Genes: APC, CTNNB1 (β-catenin), TCF7L2 

- Role: Regulates cell differentiation and growth. Mutations lead to constant activation of the Wnt signal and tumor growth. 

5. Growth factors and their receptors: 

- Genes: HER2 (ERBB2), EGFR, MET 

- Role: Mutations or expression enhance signaling, stimulating tumor growth. 

6. Involvement in angiogenesis:

- Genes: VEGFA, VEGFR 

- Role: Provide blood supply to the tumor, promoting its growth and metastasis. 

7. General mechanism: 

- Mutations and changes in these pathways lead to disruption of cell cycle regulation, increased proliferation, resistance to apoptosis and promote metastasis. 

- Modern therapies are aimed at these molecular targets.
