Study Notes
DNA Replication
- DNA polymerase recognizes the RNA primer and extends it with DNA during DNA replication.
Transcription
- RNA polymerase controls transcription.
Duchenne Muscular Dystrophy
- A mutation in the promoter region of the gene encoding dystrophin in a four-year-old boy with Duchenne muscular dystrophy would likely result in reduced or absent dystrophin production. This could lead to muscle weakness and degeneration, characteristic of the disease.
Human Genome
- The human genome consists of approximately 3 billion base pairs of DNA.
Promoter Region Mutations
- A mutation in the promoter region of a gene can significantly affect the rate of transcription, potentially leading to increased or decreased gene expression.
