Study Notes
Nucleotide Structure
- Nucleotides are composed of three primary components: a nitrogenous base, a phosphate group, and a five-carbon sugar.
- Ribose is the sugar component found in RNA; it is a pentose sugar with a hydroxyl group at the 2' carbon.
- Deoxyribonucleic acid (DNA) features deoxyribose as its sugar, which lacks one oxygen atom compared to ribose.
Nucleic Acids Function and Types
- Nucleic acids play crucial roles in the storage and transmission of genetic information within cells.
- DNA serves as the genetic material, carrying hereditary information necessary for the growth and reproduction of organisms.
- RNA functions in various roles including messenger RNA (mRNA), which conveys genetic information from DNA for protein synthesis.
Base Composition
- Both DNA and RNA contain four bases: adenine (A), guanine (G), cytosine (C), and thymine (T) is exclusive to DNA.
- Uracil (U) is a base found only in RNA, replacing thymine.
Structural Characteristics
- RNA is characterized by a single-stranded structure, leading to a flexible formation of polynucleotide chains.
- DNA typically has a double-stranded helical structure, with base pairs formed between complementary nucleotides (adenine with thymine, and guanine with cytosine).
Unique Components
- The nucleotide component unique to DNA is thymine, differentiating it from RNA where uracil takes its place.
