what is artificial twinning ?
The artificial production of monozygotic twins from the manual splitting of the early embryo
what are aseptic techniques?
A range of techniques used to culture microorganisms under sterile conditions in order to minimise contamination.
What is batch fermentation?
An industrial method of fermentation that runs for a set period of time. the culture broth is not removed until the fermentation is complete
What is bioremediation?
The use of microorganisms to remove soil and water pollutionThe use of microorganisms to remove soil and water pollution
What is biotechnology?
The field of biology involving the use of living systems to produce or transform materials. Applications include agriculture, medicine and food science.
What is brewing?
The production of beer from the steeping of barley in water, and the fermentation of the resulting product with yeast.
What are clones?
The genetically identical offspring produced as a result of cloning.
What is cloning?
A method of producing genetically identical offspring by asexual reproduction
What is continuous fermentation?
An industrial method of fermentation in which culture broth is continuously removed and extra nutrient medium is added. The fermentation conditions
remain relatively constant
In biology, what is a culture?
The growth of living matter in vitro in suitable conditions.
in biology, what is cutting?
A small section of the root or stem of an adult plant that is used in horticulture to produce natural clones.
What is enucleation?
The removing of the nucleus
What is fermentation?
A type of anaerobic respiration that does not involve an electron transport chain
What is an immobilised aminoacylase?
An immobilised enzyme that is used to produce pure samples of L-amino acids.
What are immobilised enzymes?
Enzymes which are attached to an inert, insoluble material over which the substrate passes and the reaction takes place
What is immbolilised glucoamylase?
An immobilised enzyme that can be used to breakdown dextrins into glucose
What is immobilised glucose isomerase?
An immobilised enzyme that is used to convert glucose to fructose.
What is immobilised Lactase?
An immobilised enzyme that hydrolyses lactose to glucose and galactose in the production of lactose-free mil
What is immobilised penicillin acylase?
An immobilised enzyme that is used to produce
semi-synthetic penicillins from natural penicillins.
What is micropropagnation?
The production of large numbers of clones from one parent plant using tissue culture.
What are monozygotic twins?
Identical twins formed from one fertilised egg that splits to form two embryo
What is natural cloning?
A form of asexual reproduction that takes place in plants in which a new genetically identical plant grows from a structure of the parent plant.
What are examples of where natural cloning takes place?
Stem
Leaf
Root
Bud
What is penicillin?
The first conventional, effective and safe antibiotic
What is somatic cell nuclear transfer?
The production of an embryo from the transfer of the nucleus of an adult animal cell to an enucleated egg cell in the laboratory. The nucleus and egg are fused and stimulated to divide
What sia tissue culture?
The growth of cells or tissues outside of an organism in an artificial culture medium.
