anonymous · Answer

YOU MUST NOTE THAT NO SUCH PAIR (ADENINE AND GUANINE) EXIST...IT WOULDNT BE ABLE TO FIT INTO THE STRAND..YOU DO KNO THAT BOTH OF THIS NITROGEN-CONTAININGG BASES ARE PURINES(DOUBLE RING BASE)...THEY CANNOT FIT, IT WOULD BE TO WIDE, NEITHER CAN THYMINE AND CYTOSINE FIT, IT WOULD BE TOO NARROW...THE BASE PAIR THAT EXIST IN THE T-RNA ARE U WITH A AND G WITH C...RNAS DONT USE THYMINE, DNA DOES THAT. INSTEAD THEY MAKE USE OF URACIL..AGAIN WHAT EXACTLY DO YOU SPEAK OF?
