Unit 10: Genetic Engineering

The term genetic engineering is best described as -

• creating new DNA strands from old DNA strands

• causing organisms to evolve by changing their nucleotide sequences in the zygote

• transferring genes from the genetic material of one organism to the genetic material of another organism.

• creating new organisms by combining the genes of several different organisms

Cloning is a process best described as -

• the combination of two different genomes into one new genome

• producing identical proteins

• the production of genetically identical cells or organisms

• removing unwanted genes from the genome

A scientist inserts a human gene into a cow in order to get the cow to produce human proteins in her milk. The cow is now classified as a -

• cloned animal

• mobile animal

• transgenic animal

• gene therapy animal

DNA formed by combining the DNA from two different species of organisms is called -

• recombinant DNA

• retroactive DNA

• restriction DNA

• ribosomal DNA

Which list shows the steps to genetic engineering in the correct order?

• Cut DNA - Screen - Make Recombinant DNA - Clone - Extract DNA

• Make Recombinant DNA - Cut DNA - Extract DNA - Clone - Screen

• Extract DNA - Cut DNA - Make Recombinant DNA - Clone - Screen

• Screen - Cut DNA - Clone - Extract DNA - Make Recombinant DNA

Genetic Engineering can be used in a variety of ways. If the methods of genetic engineering are used to insert human genes into the cytoplasm of bacteria, the bacteria will then -

• no longer be bacteria

• produce human proteins

• become a new species of bacteria

• destroy the foreign DNA

What is selective breeding?

• Humans cloning an organism because it has favorable traits

• Humans picking which organisms to make offspring based on their favorable traits

• Humans allowing natural selection to take its course, so that the "fittest" organisms survive

• Farmers crossing two different species to make a hybrid
