Which of the following statements are correct :

A、The determination of nucleic acid commonly used ultraviolet spectrophotometry, phosphorus determination method and sugar determination method.;
B、When renaturation of DNA, if different DNA molecules or DNA and RNA molecules are placed in the same solution, as long as there is a certain degree of base pairing relationship between these single-stranded nucleic acid molecules, hybridization can be formed between different molecules Double-stranded, this phenomenon is called nucleic acid molecule hybridization.;
C、The dideoxy method can measure the sequence of nucleic acid;
D、Western blotting can be used for DNA molecular detectionSouthern Blotting can be used for homology analysis between DNAs to determine the size and gene location of specific DNA sequences. Western blotting is commonly used in protein research
