Rna Vs Dna

Both of them are nucleic acids. And that is about the only similarity they share. ;)
One of the major differences between the two is that DNA is double-stranded and RNA is single stranded. Also, DNA contains the nucleotide T whereas RNA contains U.
RNA copies the genetic information found within DNA and uses it to assemble protein, as well as ribosomes. Hence, RNA is a crucial part in protein synthesis, being directly involved in it, whereas DNA is indirectly involved in this process.
There are three types of RNA: mRNA (messenger RNA), rRNA (ribosomal RNA) and tRNA (transfer RNA). As far as DNA is concerned, there is only one type of DNA. ;) Another difference.
Also, in some viruses the RNA replaces the DNA but the DNA will never replace the RNA. Yet another difference.
Hope that helped!

DNA carries the genetic information of a cell and consists of thousands of genes. Each gene serves as a recipe on how to build a protein molecule. Proteins perform important tasks for the cell functions or serve as building blocks. The flow of information from the genes determines the protein composition and thereby the functions of the cell.
The DNA is situated in the nucleus, organized into chromosomes. Every cell must contain the genetic information and the DNA is therefore duplicated before a cell divides (replication). When proteins are needed, the corresponding genes are transcribed into RNA (transcription). The RNA is first processed so that non-coding parts are removed (processing) and is then transported out of the nucleus (transport). Outside the nucleus, the proteins are built based upon the code in the RNA (translation).
The document has two levels, basic and advanced. This page is an introduction to both levels. You start at the basic level, then you can advance if you want more and deeper information.

There are two major chemical differences between DNA and RNA.
1. DNA molecules contain Deoxyribo sugars (which the number 2 carbon bonded with Hydrogen atom (-H).
RNA molecules contain Ribo sugars (which the number 2 carbon bonded with hydroxyl group (-OH)
2. DNA has Thymine (U). RNA has Uracil (U). Uracil is the same as Thymine but one of the Uracil's carbons lack a methyl group (-CH3).
Other differences people have already discussed which are:
1. DNA has two strands. RNA has one strand.(notes: there are viral DNA that have single strand DNA)

There is a hydroxyl group missing from the 2' carbon in deoxyribose. RNA contains ribose, which has the hydroxyl group. They also have different functions in the body.

DNA (deoxyribonucleic acid) is double stranded (double helix) and the two strands are comlementary to each other (G with C and A with T). DNA codes for everything, sometimes directly, but often indirectly. It even codes for RNA.
RNA (ribonucleic acid) is single stranded. RNA is made up of base pairs (so is DNA). 3 base pairs comprise a codon, which codes for different amino acids, which make up proteins. So with the help of ribosomes, RNA makes proteins. Also there are thre types of RNA, rRNA (ribosomal RNA) mRNA (messenger RNA) and tRNA (transfer RNA) which are complementary to eachother when making a protein, this time however the A is not complementary with T, but instead it is complementary with U.
Hope this helps!

in DNA, one of the carbons on the ribose ring has a hydrogen in place of a hydroxyl group
