A buffer is a solution encompassing a weak acid and its conjugate base in alike amounts. This combination reduces the pH change upon addition of strong acid or base by converting H1+ (or OH1-) to weaker acids or bases. This primarily consist of compounds that stabilize the pH of a solution by removing or replacing hydrogen ions. Also, substances that resist change in pH.
DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.
