Resource summary

Genes, Alleles, & The Central Dogma
1 Transcription occurs in the nucleus of the cell. (DNA -> mRNA)
2 Translation occurs in the cytoplasm of the cell. (mRNA -> protein)
3 Structural Gene
3.1 Regulatory Region
3.1.1 Determines when and how often transcription occurs
3.1.2 Transcription factors bind
3.2 Protein-encoding Region
3.2.1 Specifies the amino acid sequence of the protein
3.3 RNA polymerase binds to a special DNA sequence called the promoter
4 DNA
4.1 The basic unit of DNA is the nucleotide
4.1.1 A nucleotide consists of a phosphate, sugar, & nitrogenous base
4.1.1.1 Sugar
4.1.1.1.1 Deoxyribose in DNA
4.1.1.1.2 Ribose in RNA
4.1.1.2 Nitrogenous Bases
4.1.1.2.1 Adenine, Thymine, Guanine, & Cytosine; Uracil instead of Thymine in RNA
5 Post-translational modification of proteins
5.1 Folding, addition of sugars and/or lipids, shortening, linking to other proteins
6 Protein Targeting
6.1 A short amino acid sequence in the protein (signal sequence) directs the protein to various locations in the cell
