Question

For a single stranded DNA. if the fractions of deoxyguanylate and deoxycytidylate are 0.23 and 0.25, respectively, one could determine the fraction of the following nucleotide within the single DNA strand: A) Both A and T B)T C) Neither A nor T D)A DNA binding proteins recognize the in DNA because of its A) Sugar-phosphate backbone, sequence-independent chemical characteristics B) Major groove, sequence-dependent chemical characteristics C) Minor groove, sequence-dependent chemical characteristics D) Major groove, sequence-independent chemical characteristics E) Minor groove, sequence-independent chemical characteristics DNA melting refers to the following process: A) The double helix loses the hydrogen bonding within each basepair without losing the base stacking. B) The glycosydic bond linking the deoxyribose and the nitrogeneous base breaks and the nucleotides lost their bases. C) The double helix loses not only the hydrogen bonding within each basepair but also the base stacking. D) the phosphodiester bonds breaks and the DNA strand dissolves into individual nucleotides
