Types of DNA damage and research progress

DNA damage is a modification in the structure of DNA under the influence of endogenous or exogenous factors. DNA damage can cause different types of diseases and is closely related to genetic mutations, cancer, and aging. The cause of the corresponding reaction process is essential for the study of related cancers and other genetically related diseases. Therefore, it is essential to gain a deeper understanding of the various types of DNA damage. This paper provides a comprehensive review of recent advances in the types of DNA damage and associated reaction processes, including damage to DNA bases, nucleotides, and strands, as well as the biological implications of the damage.
