DNA is a double stranded molecule while RNA single stranded
|
|
DNA has thymine while uracil replaces thymine in RNA
|
|
DNA has ribose as its sugar while RNA has deoxyribose
|
|
DNA codes for making one polypeptide chain while RNA codes for making thousands of proteins
|
Detailed explanation-1: -RNA contains uracil, while DNA contains thymine. Explanation: RNA is different than DNA in that it 1) is single stranded (DNA is double stranded), 2) contains uracil (DNA contains thymine instead), and 3) contains a ribose sugar (DNA contains a deoxyribose sugar).
Detailed explanation-2: -Explanation: RNA differs from DNA in that it contains a ribose instead of deoxyribose, uses uracil instead of thymine, and is not only found in the nucleus like DNA. In eukaryotes, RNA is transcribed in the nucleus, then it is exported into the cytoplasm where it binds to ribosomes during translation.
Detailed explanation-3: -Because thymine has a higher resistance to photochemical mutation and makes the genetic code more durable, DNA uses it instead of uracil. This is required to store all the data required for life to function.
Detailed explanation-4: -DNA is a double-stranded molecule that has a long chain of nucleotides. RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.
