Study Notes
Nucleic Acids
- Nucleic acids are biological polymers
- They store & transmit genetic info
- Two main types: DNA & RNA
- DNA: deoxyribonucleic acid
- RNA: ribonucleic acid
DNA Structure
- DNA is a polymer of Deoxyribonucleotides
- Deoxyribose sugar
- Phosphate group
- Nitrogenous bases (adenine, guanine, cytosine, thymine)
- Double helix structure
- Bases pair: A-T, G-C
RNA Structure
- RNA is a polymer of Ribonucleotides
- Ribose sugar
- Phosphate group
- Nitrogenous bases (adenine, guanine, cytosine, uracil)
- Single-stranded
- Types: mRNA, tRNA, rRNA
Differences Between DNA and RNA
- DNA: double-stranded, deoxyribose sugar, thymine
- RNA: single-stranded, ribose sugar, uracil
Genetic Material
- DNA is genetic material in most organisms
- Some viruses have RNA as genetic material (e.g., HIV)
- Amount of genetic material varies depending on the species, some viruses have circular DNA others linear
Nucleotide
- A nucleotide is the monomer of nucleic acids
- It's composed of a sugar, a phosphate group, and a nitrogenous base.
- The phosphate group is an acidic part, thus DNA & RNA are acidic in nature
