1. There are different types of nucleic acids, each having its own characteristic function.
2. DNA has a structure different from RNA. Structurally there are 3 forms of DNA. Structures of mRNA, rRNA and rRNA have been described. RNA has primary, secondary and tertiary level structural organization.
3. Nucleic acids are polymers of nucleotides. There are two types of nucleic acids, DNA and RNA.
4. The DNA is further subdivided into three (3) forms namely: A form, B form and Z form.
5. DNA can be denatured and renatured. DNA is highly condensed in the chromosome and its size can be determined under centrifugal field.
6. RNA has a primary, secondary and tertiary structures. DNA and RNA have differences and similarities. DNA serves in storage and transmission of genetic material from one generation to another or from parents to offsprings.
7. Messenger RNA carries genetic information from nucleus to the cytoplasm.
8. Transfer RNA carries amino acids to the site of protein synthesis. Ribosomal rRNA serves as the structural framework of the ribosome.
