Area of Science:

  • Molecular Biology
  • Genetics
  • Cell Biology

Background:

  • DNA damage arises from environmental and internal sources.
  • DNA double-strand breaks (DSBs) represent the most hazardous DNA lesions.
  • Rapid activation of repair pathways is vital for cell survival.

Purpose of the Study:

  • To explore the function of ubiquitin and ubiquitin-like proteins in DNA damage response.
  • To elucidate the role of these proteins in DNA repair mechanisms.
  • To enhance understanding of DSB signaling pathways.

Main Methods:

  • Literature review on DNA damage response pathways.
  • Analysis of studies investigating ubiquitin and ubiquitin-like proteins.
  • Synthesis of current knowledge on DSB repair mechanisms.

Main Results:

Fixing Double-strand Breaks

The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

Homologous Recombination

The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Overview of DNA Repair

In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.
