Questions & Step-by-Step Solutions
Which of the following is not a component of DNA? (2018)
Step 1: Understand what DNA is. DNA stands for deoxyribonucleic acid, which is the molecule that carries genetic information.
Step 2: Identify the components of DNA. DNA is made up of nucleotides, which consist of three parts: a phosphate group, a sugar called deoxyribose, and a nitrogenous base.
Step 3: Compare DNA and RNA. RNA stands for ribonucleic acid, and it has a different sugar called ribose instead of deoxyribose.
Step 4: Determine which option is not a component of DNA. Since ribose is found in RNA and not in DNA, it is the correct answer.
