DNA is made up of two strands and each strand of the original DNA molecule serves as a template for the production of the complementary strand, a process referred to as semiconservative replication.Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.NA 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. Nucleotides in DNA contain a deoxyribose sugar, a phosphate, and a nucleobase.
Initiation of DNA replication 1. Origins of replication a. Specific sequence of nucleotides b. recognized by proteins that bind to DNA-initiator proteins 2. DNA helix unwinds-caused by helicase enzymes 3. bacteria have a single origin of replication B. Initiation of DNA replication 1. Origins of replication a.
