Dna structure and replication essay
Dna is well-suited to perform this biological function because of its molecular structure, and because of the development of a series of high performance enzymes that are fine-tuned to interact with this molecular structure in specific ways. The process of dna replication the process of dna replication plays a crucial role in providing genetic continuity from one generation to the next knowledge of the structure of dna began with the discovery of nucleic acids in 1869. Dna replication to understand the process of dna replication, you much first be familiar with the structure of dna resembling a twisted ladder, dna is a double helix formed with nucleotides, a phosphate and sugar backbone, and nitrogenous bases.
Dna topoisomerases unwind the dna strand and counteract the excessive winding that may result if a replication fork is to be created thus dna topoisomerases unzip the double helix in order for the rest of the enzymes to attach to the replication fork.
