Genet

What is a benefit of selective breeding?

• Gets desired traits from parents

• Gets rid of undesired traits

• Allows harmful recessive traits to be passed down.

• Takes a lot of time and is expensive.

What is the unknown genoytpe?

• BB

• Bb

• bb

• bB

"The modification of characteristics in an organism through the manipulation of genes," describes which term?

• Genetic engineering

• DNA fingerprinting

• Gel electrophoresis

• Cloning

Inserting human DNA into a bacterial plasmid to create insulin-producing bacteria is an example of:

• Recombinant DNA

• Bacterial Transformation

• Cloning

• Selective breeding

When fragments of DNA are connected from different sources, this creates:

• A plasmid

• A clone

• Recombinant DNA

• Fragmented DNA

Bacterial DNA that is often circular or in the shape of a ring is called a:

• Clone

• Plasmid

• Fragment

• Recombinant DNA

An alternative to genetic engineering is carefully choosing the parent organisms and breeding them to arrive at desired traits in the offspring. This is called:

• Genetic engineering

• Bacterial Transformation

• Cloning

• Selective breeding

Organisms that have had DNA from other organisms inserted into their DNA to produce certain traits are called:

• Plasmids

• Clones

• Transgenic organisms

• Recombinant organisms

Which of the following means of genetic engineering would have the greatest impact on world hunger?

• Inserting human DNA into bacterial DNA for insulin production

• Manipulating DNA in trees to require less water

• Engineering crops for greater nutritional content

• Modifying genes to achieve a desirable phenotype
