Study Notes
Factors Affecting Development and Cloning
- Teratogens are substances that cause congenital disorders in a developing embryo or fetus, including alcohol, cigarettes, recreational drugs, medications, and infections/viruses.
- Thalidomide, a drug prescribed for morning sickness, caused mutations in the SALL4 transcription factor and changed the growth and development of new blood vessels, leading to birth defects.
- Tylenol exposure during pregnancy has been associated with higher rates of ADHD and ASD in children, but it is unclear if the medication itself causes these conditions.
- Progeria is a genetic disorder that accelerates aging and shortens lifespan, caused by a variant in the LMNA gene that prevents DNA repair.
- Longevity is influenced by various genes related to immune function, insulin secretion, stress response, cell cycle, DNA repair, lipid metabolism, nutrient metabolism, and antioxidant enzymes.
- Fragile X Syndrome is caused by a lack of the FMR1 protein needed for typical brain development, and epigenetic factors can influence the onset of mental illnesses like schizophrenia, bipolar disorder, Alzheimer's disease, autism spectrum disorders, cardiovascular disease, obesity, and diabetes.
- Clones are not exact replicas of their donors due to premature cellular aging, altered gene expression, more mutations, X chromosome inactivation, mitochondrial DNA, and environmental differences.
- Dolly the Sheep was the first mammal cloned from adult cells, but she had shorter telomeres and died young, highlighting the limitations of cloning.
- Cloning can be affected by epigenetic factors that alter gene expression and lead to differences in physical and behavioral traits.
- Human cloning is a controversial topic, with ethical concerns about the rights of clones and implications for generational wealth and crime.
- Development and aging are influenced by various factors, such as lifestyle choices, genetic predisposition, and environmental exposures.
- Understanding the role of genetics and epigenetics in development and cloning can inform medical treatments and ethical debates.
