If the base pairs in a dna strand were held together with covalent bonds instead of hydrogen bonds, how would cells have to operate differently? a) new dna would need to be made each time the strand was opened. b) the cell would have to take in and use more energy in order to break the covalent bonds. c) each time the dna strand opened the cell would need to replace the nitrogenous bases. d) the cell could only open and close the dna strand when it replicated.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
