Question

What is difference between RNA and DNA ?

Answer 1

Step-by-step explanation:

DNA

1- Made up of deoxyribose sugar

2- Double-stranded

3- Chemically and structurally stable

4-Nitrogenous bases- adenine guanine cytosine and thymine

5- A slower rate of variation (through recombination)

RNA

1- Made up of ribose sugar

2- Single-stranded

3- Chemically and structurally unstable (presence of 2′ hydroxyl group in ribose sugar make it more reactive and hence unstable)

4- Nitrogenous bases— adenine, guanine, cytosine & uracil

5- A faster rate of variation (through mutation)

Answer 2

While both DNA and RNA are used to store genetic information, there are clear differences between them.

Step-by-step explanation:

1. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring.
2. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.
3. DNA is stable under alkaline conditions, while RNA is not stable.
4. DNA and RNA perform different functions in humans. DNA is responsible for storing and transferring genetic information, while RNA directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins.
5. DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. Uracil differs from thymine in that it lacks a methyl group on its ring.
