"Advances in Genetics Research" presents original research results on the leading edge of genetics discovery. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum. In this continuing series compilation, the authors present and discuss varied topical data such as genetic modification of stem cells in ex vivo gene therapy; viral RNA polymerases; polymerase chain reactions; genetic modification to improve the therapeutic potential of oncolytic clostridia and cloning of the B2-microglobulin from sea bass.
