Question

What are three key differences between DNA and RNA?

Answer 1

1. DNA stands for Deoxyribonucleic Acid. The sugar portion of DNA is 2-Deoxyribose.

RNA stands for Ribonucleic Acid. The sugar portion of RNA is Ribose.

2. The helix geometry of DNA is of B-Form (A or Z also present).

The helix geometry of RNA is of A-Form.

3. DNA is a double-stranded molecule consisting of a long chain of nucleotides.

RNA usually is a single-strand helix consisting of shorter chains of nucleotides

Answer 2

dna:
1. found in nucleus

2. sugar is deoxyribose

3. bases are a,t,c,g

rna:
1. found in nucleus and cytoplasm

2. sugar is ribose.

3. bases are a,u,c,g
