About the Lecture
The lecture Genetics - Mutations by Jonathan Clark is from the course Biology: Basic. It contains the following chapters:
- Changes in the Gene Pool
- Mutation
- Population Genetics
- Cloning and Detection of Gene Mutations
- Cell Genetics and Genetic Engineering
- Summary
Included Quiz Questions
Down's syndrome is caused by the :
- presence of one extra chromosome number 21
- Three chromosomes number 21
- absence of one chromosome number 21
- absence of both chromosomes number 21
- Four chromosomes number 21
Gene mutations maybe detected by the use of
- a hybridisation probe
- a complementary base sequence to the mutant gene sequence
- electrophoresis
- non-coding repeating sequences
- RNA polymerase enzyme
A mutation can be defined as
- a permanent change in the sequence of bases of an organism
- a substitution, deletion or insertion of a base or bases
- a temporary change in the sequence of bases of an organism
- a change to the sugar-phosphate DNA backbone
- formation of a triple DNA helix
Down's syndrome is an example of a ------- mutation
- trisomy
- chromosomal
- monosomy
- gene
- protein
A clone is defined as an organism that
- has exactly the same DNA as another organism
- has been produced through asexual reproduction
- has exactly the same appearance as another organism
- has been produced through sexual reproduction (with the exception of monozygotic twins)
- is a virus or non-living particle
Since the 1970s human insulin has been produced in large quantities by
- recombinant DNA technology
- genetic engineering of human genes into bacterial cells
- growth of genetically recombinant bacteria carrying the human insulin gene
- stem cell technology
- tissue culture
