1. Ribonucleotides in DNA - Application in genome-wide DNA polymerase tracking and physiological role in eukaryotes
Abstract : The genetic code in the eukaryotic cell is stored in the form of DNA, which is more resistant to hydrolysis than RNA. Replication fidelity and DNA repair mechanisms are in place to ensure genomic integrity to preserve the information encoded. READ MORE

2. The consequences of DNA lesions for mitochondrial DNA maintenance
Abstract : Eukaryotic cells have their own energy-producing organelles called mitochondria. The energy is stored in the adenosine triphosphate (ATP) molecule and is produced via the oxidative phosphorylation process inside the mitochondria. Thirteen of the essential proteins required for this process are encoded on the mitochondrial DNA (mtDNA). READ MORE

3. Development of benzoquinoquinoxaline derivatives as triplex-specific probes : Recognition of DNA structures at repeats sequences
Abstract : Repeat sequences are associated with several human diseases, such as Friedreich’s ataxia, polycystic kidney disease and cancer. These sequences can form non-B-DNA structures, including triplex (H-DNA) DNA, and are associated with genomic instability and altered gene expression. READ MORE

4. Role of Non-Homologous End-Joining in Repair of Radiation-Induced DNA Double-Strand Breaks
Abstract : Efficient and correct repair of DNA damage, especially DNA double-strand breaks (DSBs), is vital for the survival of individual cells and organisms. Defects in the DNA repair may lead to cell death or genomic instability and development of cancer. READ MORE

5. Chromosomal Instability and Genomic Amplification in Bone and Soft Tissue Tumours
Abstract : Acquired genetic abnormalities are found in all types of malignant tumours and may contribute to neoplastic processes by altering protein structure or dosage. Many bone and soft tissue tumours (BSTT) are characterised by complex patterns of chromosome changes, including extensive intratumour heterogeneity and amplification of DNA sequences. READ MORE
