How are RNA and DNA different and similar?

1. The RNA molecule is a shorter polymer than DNA. She is responsible for the transfer of biological information stored in DNA molecules, which store information and transmit it by inheritance. DNA is a double strand and RNA is a single strand. RNA is found in ribosomes, and DNA is in the nucleus, in mitochondria, in chloroplasts. RNA is made up of ribonucleotides, DNA is made up of deoxyribonucleotides.
2. DNA and RNA are present in all living cells. Both of these terms refer to nucleic acids.
