What is genetic engineering?

• adapting an environment to an organism's strengths

• modifying an organism by changing its DNA

• driving a train

Selective Breeding is

• when a breeder chooses what traits s/he wants the offspring to have

• when the offspring chooses what traits s/he wants to have

• when it is selected by chance what traits an offspring will have

Some larger purebred dogs have hip problems because of

• hybridization

• PCR

• inbreeding

When DNA from different organisms are brought together, ___ is created

• transfer RNA (tRNA)

• recombinant RNA (rRNA)

• recombinant DNA (rDNA)

• ribosomal RNA (rRNA)

When an organism has genes from another organism it is

• transgenic

• purebred

• a clone

CRISPR is

• a new way of cooking

• used to change an individual's DNA

• when the DNA from multiple organisms are merged together

Restriction enzymes

• count DNA bases

• cut DNA bases

• stick to DNA bases

A forensic scientist is given a very small amount of DNA. What technique do will be used to make more DNA to do testing on?

• PCR

• plasmid

• inbreeding

• selective breeding

When an enzyme cuts a DNA strand at a specific spot it creates

• a plasmid

• an exact copy

• sticky ends

A clone is

• a similar copy to an original created from two sets of DNA

• an exact copy of the parents that donated their cells

• an exact copy of an individual made from an adult single cell
