This book “Advances in Horticultural Crops” has been design to provide overall understanding of all aspects related to the study of horticultural crops. Hybridization is the process of combining two complementary single-stranded DNA or RNA molecules and allowing them to form a single double-stranded molecule through base pairing. All elements around us, behave in strange yet surprising ways. Electrons like to be in pairs, so these atoms, called free radicals, scavenge the body to seek out other electrons so they can become a pair. Ans. The electronic configurationof these elements, along with their properties, is a unique concept to study and observe.
