Question

what is RNA explain in breaf and what is difference between RNA and DNA

Answer 1

RNA- Ribonucleic acid. It is a nucleic acid present in all living cells.RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). A central tenet of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins.
Difference between RNA & DNA-
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.

Answer 2

RNA stands for ribonucleic acid. It is an important molecule with long chains of nucleotides. A nucleotide contains a nitrogenous base, a ribose sugar, and a phosphate. Just like DNA, RNA is vital for living beings.
Function of RNA is the main job of RNA is to transfer the genetic code need for the creation of proteins from the nucleus to the ribosome

Difference between RNA and DNA
DNA in propagation is self replicating.
RNA in propagation is synthesized from DNA on an as needed basics.
DNA  in base pairing is AT(adenine thymine)GC(guanine cytosine)
RNA in base pairing is AU(adenine uracil)GC(guanine cytosine)
