The volcanic eruption is a natural phenomena that results in the liberation of the lava from the heap of the earth along with the gases. The volcanic eruption causes major damages to the vegetation lying above the erupted crater of the volcano.

DNA ligase is an enzyme that repairs irregularities or breaks in the backbone of double-stranded DNA molecules. It has important role in the process of DNA replication and DNA repair. It has three general functions: It seals repairs in the DNA, it seals recombination fragments, and it connects Okazaki fragments (small DNA fragments formed during the replication of double-stranded DNA). DNA ligase functions by forming a bond between the end of a “donor” nucleotide and the end of an “acceptor” nucleotide.
