Compare and contrast the similarities and differences between the DNA and RNA molecules.?

DNA has two nucleotide strands running anti parallel
DNA has A-T, G-C nitrogen base bonds
DNA is the molecule that codes for the genetic information

RNA is single a single stranded nucleotide
RNA has A-U, G-C nitrogen base bonds (uracil instead of thymine)
RNA strands are required for protein synthesis, they do not code for genetic information and they are formed as template strands of DNA

Differences>
- DNA - double stranded
- RNA - single stranded

- DNA - contains deoxyribose sugar
- RNA - contains ribose sugar

- DNA - nitrogenous bases are A , T , C,  and G.
- RNA - nitrogenous bases are  A, U, C and G.

- DNA - It serves as heriditary material in most of the organisms
- RNA - It is heriditary material for most of the viruses.

- DNA - It consists of large number of nucleotides [ about 4 million]
- RNA - it consists of less number of nucleotides [ about 12,000].

- DNA - Present in nucleus , mitochondria and chloroplasts
- RNA - present throughout the cytoplasm except vacoules.

- DNA - it is fuelgen +ve [ stain].
- RNA - it is fuelgen -ve [ stain].

Similarites
> Both are nucleic acids.> Both are found in the cell and are important part for the transmission of the genetic content.> Both are made of 4 bases, a sugar and a phosphate group (actual composition differs)
