Study Notes
Components of a Nucleotide
- A nucleotide consists of three components: a sugar molecule, a phosphate group, and a nitrogenous base.
Nitrogenous Bases
- Purine bases in DNA are adenine (A) and guanine (G).
- Adenine (A) base pairs with thymine (T) in DNA.
Hydrogen Bonds in DNA
- Hydrogen bonds are weak chemical bonds that hold the two complementary strands of DNA together.
DNA Synthesis
- The function of DNA polymerase during DNA synthesis is to add nucleotides to a growing DNA strand.
- During DNA synthesis, an existing strand of DNA serves as a template for the creation of a new complementary strand.
- The two duplicate molecules formed during DNA synthesis are called identical sister chromatids.
Structure of DNA
- The structure of DNA is called a double helix.
Codon and Gene Function
- A codon is a sequence of three nucleotides that codes for a specific amino acid or stops protein synthesis.
- The function of a gene in DNA is to provide the instructions for creating a specific protein or performing a specific cellular function.
