DNA and RNA Flashcards
1
Q
What is the type of sugar in DNA and RNA?
A
• It’s deoxyribose in DNA.
• It’s ribose in RNA.
2
Q
What does a purine and pyrimidine base contain?
A
• A purine base contains two carbon-nitrogen rings joined together.
• A pyrimidine base only has one carbon-nitrogen ring. So a pyrimidine base is smaller than a purine base.
3
Q
What are the purine bases in DNA and RNA?
A
Adenine and Guanine in both.
4
Q
What are the pyrimidine bases in DNA and RNA?
A
• Cytosine and thymine in DNA.
• Cytosine and uracil in RNA.
5
Q
What are the number of polynucleotide strands in DNA and RNA?
A
• DNA contains two.
• RNA contains one.
6
Q
What is the location of DNA and RNA in eukaryotic cells?
A
• DNA is in the nucleus, chloroplast and mitochondria.
• RNA is in the nucleus and cytoplasm.
