    Area of Science:

    • Biochemistry
    • Molecular Biology

    Background:

    • Polyamines like spermine and putrescine play crucial roles in cellular processes.
    • Nucleases are enzymes essential for nucleic acid metabolism and regulation.
    • Understanding polyamine-nuclease interactions is vital for molecular biology research.
