The meaning of DOUBLE HELIX is a helix or spiral consisting of two strands in the surface of a cylinder that coil around its axis; especially : the structural arrangement of DNA in space that consists of paired polynucleotide strands stabilized by cross-
In biology, "double helix" is a term used to describe the structure ofDNA. A DNA double helix consists of two spiral chains of deoxyribonucleic acid. The shape is similar to that of a spiral staircase. DNA is anucleic acidcomposed of nitrogenous bases (adenine, cytosine, guanine, and thymi...
While they recognized that many details remained to be discovered, they suggested that the double helix could answer one of the fundamental questions of biology: that is, what happens at the molecular level to provide a template for the accurate replication of genetic information 展开 ...
