Elements in Genomic DNA.

DNA usually exists as a double-stranded structure, with both strands coiled together to form the characteristic double-helix. Each single strand of DNA is a chain of four types of nucleotides: adenine, cytosine, guanine, and thymine. DNA replication, the basis for biological inheritance, is a fundamental pro- cess occurring in all living organisms to copy their DNA. The book has been designed for university students and teachers dealing with genetics, molecular biology, genetic engineer- ing and biochemistry.
