Hi , please I need a comment and question for this post.

Examine three (3) differences between DNA and RNA then explain two (2) main reasons why DNA is the most favorable molecule for genetic material. Next suggest how RNA compares to DNA in regards to genetic material.

DNA is a deoxyribonucleic acid, whereas, RNA is a ribonucleic acid. Although three of the bases (adenine, cytosine, and guanine) are the same in RNA and DNA nucleotides, the fourth base in RNA is uracil (U), not thymine as it is in DNA. Last difference is that the basic component in DNA is genes, whereas, RNA is the messenger of those genes. One main reason why DNA is the most favorable molecule is because it stores cell's heritable information. Another is because enzymes use the gene's DNA sequence as a template to assemble a strand of RNA. DNA and RNA are long linear polymers, called nucleic acids, that carry information in a form that can be passed from one generation to the next. Genetic information is stored in the sequence of bases along a nucleic acid chain. Although RNA probably functioned as the genetic material very early in evolutionary history, the genes of all modern cells and many viruses are made of DNA. DNA is replicated by the action of DNA polymerase enzymes.
