WebFeb 21, 2024 · INTRODUCTION. Homologous recombination (HR) is a DNA strands exchange process essential for multiple pathways of genome maintenance and plasticity in all kingdoms of life (1, 2).Defects in any of these pathways lead to deleterious consequences, such as cell death or various types of cancer ().HR relies on the pairing of … In polymer chemistry, polymerization (American English), or polymerisation (British English), is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. There are many forms of polymerization and different systems exist to categorize … See more Step-growth and chain-growth are the main classes of polymerization reaction mechanisms. The former is often easier to implement but requires precise control of stoichiometry. The latter more reliably affords high … See more • Cross-link • In situ polymerization • Metallocene • Plasma polymerization See more
