Study Notes
- DNA falls under nucleic acids category along with RNA and serves to store and transmit hereditary information.
- Nucleic acids pass on genetic information based on the sequence of nucleotides.
- RNA and DNA are both polymers made of nucleotide monomers, but RNA is single-stranded while DNA is double-stranded.
- Nucleotide monomers consist of a five-carbon sugar, a phosphate group, and a nitrogen base.
- DNA nucleotides have four nitrogen bases (adenine, thymine, guanine, cytosine), while RNA nucleotides have uracil instead of thymine.
- Nucleic acids are composed of carbon, hydrogen, oxygen, nitrogen, and phosphorus elements.
- DNA and RNA share a sugar-phosphate backbone and nitrogen bases held together by hydrogen bonds.
- DNA is double-stranded and follows base pairing rules where adenine pairs with thymine and guanine pairs with cytosine.
- DNA strands run anti-parallel to each other, with one strand being upside down compared to the other.
- New nucleotides are added to the three prime end of growing DNA or RNA strands, following the five prime to three prime direction.
Test your knowledge on the structure, composition, and function of DNA and RNA. Learn about nucleic acids, nucleotides, nitrogen bases, sugar-phosphate backbone, base pairing rules, and the differences between DNA and RNA.
