WebSep 26, 2008 · Alkali denaturation changed most negative superhelical turns and knotting of the DNA molecules into double strand unwinding, and it shrank circular molecules with topological constraint. These results suggested that the plasmid DNA had ever been a stable conformation of single strand DNA due to alkali denaturation. WebTHE reaction of a solution of DNA with an alkylating agent such as dimethyl sulphate results in the production of acid as the alkylating agent is hydrolysed by water.
WebHemoglobin Rainier, a new hemoglobin variant associated with erythrocytosis, was found in six members of a Caucasian family.
