- Double-helical DNA has major and minor grooves becauseA. DNA-binding proteins twist the DNA into a specific shaveB. The A:T and G:C basepairs have different dimensionsC. Purines, being larger, form the major groove while pyrimidines, being smaller, form the minor grooveD. The phosphoribose backbones of the two strands are not diametrically oppositeE.The bases in the genetic material of Skrulls are named A, B, C and E. A pairs with E and B pairs with C. Therefore there are A-E base pairs and B-c base pairs. A human scientist has four sequences read 5’ to 3’. A single strand of the genetic material is given (assuming that Skrull genetic material is double stranded).
