Study Notes
Parkinson's Disease
- Caused by mutations in genes coding for alpha-synuclein.
- Symptoms include uncontrollable tremors, difficulty walking, and loss of coordination.
- Geneticists can identify mutations using gene mapping.
Starch vs. Glycogen
- Starch is an energy storage molecule in plants.
- Glycogen serves as an energy storage molecule in animals.
- Starch is a polymer primarily made of glucose.
Mitosis and Errors
- Error-free mitosis is essential to prevent healthy cells from becoming cancerous.
Interphase
- Prepares cells for mitosis through cell growth and DNA replication.
Limiting X-ray Exposure
- Wearing a protective vest reduces exposure to X-rays.
Phospholipid Bilayer Formation
- Phospholipids form a bilayer in water due to hydrophilic phosphate portions attracting water and hydrophobic lipid portions repelling water.
RNA Complementarity
- The complementary RNA strand for the DNA sequence GTTCCAGAG is CAAGGUCUC.
Cystic Fibrosis Mutations
- Cystic fibrosis arises from mutations in the CFTR gene, with nonsense mutations causing premature translation termination.
Protein Synthesis Site
- Ribosomes are the primary sites of protein synthesis.
Friedrich Miescher's Contribution
- Extracted and observed DNA for the first time from white blood cells.
Y-chromosome Analysis
- Y-chromosome analysis can identify a boy's parent using only paternal DNA samples.
Element in DNA and Protein
- Nitrogen is found in both DNA and proteins.
Initiation of Protein Translation
- A peptide bond formation between mRNA subunits is required to begin translation.
Immediate Energy Source
- Glucose serves as an immediate energy source for the body.
Lac Operon Hypothesis Testing
- Adding allolactose to E. coli growth media increases the rate of lactose metabolism.
Disease-fighting Proteins
- Antibodies are the type of protein that combats diseases.
RNA Coding Errors
- Errors in RNA coding lead to incorrectly formed proteins.
Human Genome Size
- The human genome consists of approximately 20,000-25,000 genes.
Diet and Cardiovascular Risk
- An increase in saturated fat consumption raises the risk of cardiovascular disease.
Chromosomal Changes and Disorders
- Robertsonian translocation is a chromosomal defect caused by chromosome fragment attachment.
DNA Technology and Consequences
- Long-term studies of DNA technology are necessary to understand potential outcomes.
Chromosomal Translocation
- A translocation occurs when part of a chromosome breaks off and attaches to another chromosome.
Genetically Engineered Medicine Risks
- Use of antibiotic-resistant gene markers may lead to increased antibiotic resistance in humans.
Molecules Lacking Carbon Atoms
- Water is a biological molecule that does not contain carbon atoms.
Radiation Exposure and Health
- Small amounts of radiation from X-rays typically do not significantly impact health.
