Mutagens and Mutations
This type of mutation involves a change in a single nucleotide.
What is point mutation?
This term refers to the total genetic information in a population.
What is gene pool?
This enzyme cuts DNA at specific sequences.
What is restriction enzymes?
This term refers to the use of living organisms in technology.
Biotechnology
This mutagen can cause thymine dimers to form in DNA.
This process involves the movement of alleles between populations.
What is gene flow?
This circular DNA molecule is used as a vector.
What is plasmid?
This reproductive technology introduces sperm artificially.
What is artificial insemination?
This type of mutation affects large sections of chromosomes.
What is chromosomal mutation?
This process introduces new alleles into a population.
What is mutation?
This famous sheep was the first cloned animal.
What is Dolly the Sheep?
This technique identifies individuals using DNA patterns.
What is DNA profiling?
This distinguishes somatic mutations from germ-line mutations.
Only germline mutations are inherited
This process causes random changes in allele frequency.
What is genetic drift?
This type of organism contains DNA from another species.
What is transgenic organism?
Explain one benefit of biotechnology in agriculture.
Increased yield; pest resistance ...
This can explain why mutations in non-coding DNA can still affect phenotype.
Non-coding DNA can regulate gene expression
This process increases genetic variation through the fusion of a random combination of gametes.
What is fertilisation?
Explain how recombinant DNA technology is used to produce useful proteins.
Insert gene into host → host produces protein
Evaluate one impact of biotechnology on biodiversity.
Genetic diversity may be reduced in the long term
