Question

What is the difference between DNA and RNA??

Answer 1

DNA is deoxyribose and RNA is ribose.
in DNA thymine is present while in RNA uracil is present instead of thymine.
DNA follows CHARGAFF'S RULE while RNA does not.
DNA has the property of formation by self replication while in RNA formation is done by transcription(from DNA).

Answer 2

DNA means Deoxyribonucleic acid
RNA means Ribonucleic acid

RNA is found in every cell but DNA is found only in Eukaryoic cell.Actually u can say Dna is an advanced form of rna.

Answer 3

u may also refer to this link
it has a table of differences

Answer 4

Hi @Kritika_krits..

Just to add to what the others have said. Firstly, I guess that the most 'striking' difference lies in the names - Deoxyribonucleic acid for DNA and Ribonucleic acid for RNA. You should know that both DNA and RNA contain a sugar, a nitrogenous base and a phosphate group. The difference in the name is due to the sugar they contain. The DNA has the deoxyribose (due to the lack of an oxygen atom on the 2' carbon atom of the sugar) and RNA has the ribose sugar. Also, there is a difference in their bases. Both have adenine, cytosine and guanine but for the fourth base, DNA has thymine while RNA has uracil. Other differences include:
- DNA is found in nucleus, mitonchondria but never in cytoplasm while RNA is found in both nucleus and cytoplasm.
- DNA consists of 2 helical strands whilst RNA are single stranded but they can form double strands sometimes.
- There are A, B, C, D & E forms of DNA while RNA can be in the form of t-RNA, m-RNA, r-RNA.
- Under natural conditions DNA can form RNA but RNA cannot form DNA.

That's pretty much about the differences I think. I hope it helps.

@Ramsha_Shahid that link is really nice.. Thanks for sharing..

Answer 6

From how I understand it, RNA is the complementary gene sequence of DNA. And RNA have uracil instead of thymine (neglecting mutation factor)
