Q: Which of the following bases is found in RNA but not in DNA?
Solution:
RNA contains uracil instead of thymine, which is found in DNA.
Steps: 7
Show Steps
Step 1: Understand that both RNA and DNA are types of nucleic acids.
Step 2: Learn that nucleic acids are made up of building blocks called nucleotides.
Step 3: Know that each nucleotide contains a sugar, a phosphate group, and a nitrogenous base.
Step 4: Identify the nitrogenous bases: DNA has adenine (A), thymine (T), cytosine (C), and guanine (G).
Step 5: Identify the nitrogenous bases in RNA: RNA has adenine (A), uracil (U), cytosine (C), and guanine (G).
Step 6: Compare the bases: Notice that RNA has uracil (U) instead of thymine (T), which is found in DNA.
Step 7: Conclude that uracil is the base found in RNA but not in DNA.
