I saw some research papers, they had been reported the DNA cleavage by using several type of nanoparticles. What is the use of DNA cleavage?

Can I base on reverse DNA sequences to perform alignment, convert to amino acids and GenBank submission?

I have reverse sequences (AB1 format), can I base on reverse DNA sequences to perform nucleotide alignment, convert nucleotides to amino acids and deposit the sequence in GenBank database?

DNA cleavage can be a (geno-) toxic response to radiation or a chemical agent, resulting in cell death. If this can selectively induced in cancer cells, then it can be used as a therapy.

Thanks Hugh

@ Suresh, DNA cleavage is important in terms of its greater cell lethality than that from single strand cleavage.
