Study Notes
Genetic Disorders
- A mutation that occurs spontaneously before embryonic development is called a sporadic mutation.
- Mendelian disorders are the type of genetic disorders most commonly discussed when referring to disorders with a single genetic cause.
- There are approximately 6,000 known genetic disorders.
- Multifactorial disorders are caused by a mutation in multiple genes.
- Autosomal recessive inheritance occurs when a genetic disorder is inherited from two parents who are carriers of a faulty gene.
Polymers
- Polymerization is the process by which polymers are formed from many small molecules.
- Due to their large molecular mass, polymers possess high molecular weight, high viscosity, and high melting points.
- The term 'polymer' means 'many parts' in Greek.
- The term 'polymer' was coined by Jons Jakob Berzelius in 1833.
- The two types of polymers mentioned are natural polymers and synthetic polymers.
