DNA ligase

DNA ligase is an enzyme that plays a crucial role in the process of DNA replication and repair. It acts like a molecular glue, connecting fragments of DNA by forming bonds between them. This is particularly important when cells replicate their DNA, as the strands often break into smaller pieces. By sealing these gaps, DNA ligase ensures the integrity and continuity of genetic information, which is essential for proper cell function and reproduction. Without DNA ligase, the DNA would remain fragmented, leading to errors and potential issues in cell growth and division.
