Focused Finish: Mutations, Punnett Squares, Transgenic Organisms

Front

What is Selective Breeding?

Back

Selective Breeding is the process by which humans choose specific plants or animals to breed based on desired traits.

Front

What are restriction enzymes?

Back

Restriction enzymes are proteins that cut DNA at specific sequences, creating DNA fragments.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in an organism's traits.

Front

What type of mutation is represented by the change from T-G-A-C-C-A to T-G-A-G-C-A?

Back

Substitution mutation, where one base is replaced by another.

Front

What is the purpose of pedigrees in genetics?

Back

Pedigrees are used to track traits and inheritance patterns in families.

Front

What is a transgenic organism?

Back

A transgenic organism is one that has been genetically modified to contain DNA from another species.

Front

What is gel electrophoresis used for?

Back

Gel electrophoresis is a technique used to separate DNA fragments based on their size.

Front

What is the role of DNA helicase?

Back

DNA helicase is an enzyme that unwinds the DNA double helix during replication.

Front

What is the difference between insertion and deletion mutations?

Back

Insertion mutations add one or more nucleotides to the DNA sequence, while deletion mutations remove nucleotides.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.
