Overview

DNA replication is the biological process through which a cell creates an exact copy of its DNA. It occurs in all living organisms to ensure the accurate transmission of genetic information. It takes place during the S phase of the cell cycle, before cell division. The process begins at specific locations called origins of replication, where the DNA double helix is unwound by the enzyme helicase, creating two single strands. Each strand serves as a template for the formation of a new complementary strand, facilitated by the enzyme DNA polymerase. The result is two identical DNA molecules, each containing one original and one newly synthesized strand, ensuring genetic consistency in daughter cells. DNA replication is crucial for growth, development, and tissue repair in multicellular organisms, and for reproduction in single-celled organisms. This book presents the complex subject of DNA replication in the most comprehensible and easy to understand language. The topics covered in this extensive book deal with the core topic of replication of DNA. For all those who are interested in molecular and cellular biology, this book can prove to be an essential guide.
