Q: What is a key difference between DNA and RNA?

Solution: RNA contains uracil (U) in place of thymine (T), which is found in DNA, making this a key difference between the two nucleic acids.

Steps: 5

Step 1: Understand that DNA and RNA are both types of nucleic acids.
Step 2: Know that DNA stands for deoxyribonucleic acid and RNA stands for ribonucleic acid.
Step 3: Learn that DNA has four bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
Step 4: Learn that RNA also has four bases: adenine (A), uracil (U), cytosine (C), and guanine (G).
Step 5: Notice that the key difference is that RNA has uracil (U) instead of thymine (T), which is found in DNA.
