Explanation: DNA is double stranded helix structure that is made up of a phosphate group, a Nitrogenous base which include the purine and pyrimidime and a 5 carbon deoxyribose sugar. Between the strand is an hydrogen bond that hold them together
DNA replication occur by the unwinding of this double helix strand and the breaking of the hydrogen bond by the enzyme helicase.
The double-helix shape allows for DNA replication and protein synthesis to occur. In these processes, the twisted DNA unwinds and opens to allow a copy of the DNA to be made. ... As the new strands form, bases are paired together until two double-helix DNA molecules are formed from a single double-helix DNA molecule.
Nitrates are used by plants to make amino acids and proteins. Most of the phosphorus cycle takes place at ground level. Phosphate is released by the slow breakdown of rocks. What two main biological processes are responsible for the cycling of oxygen?
