Quiz 9 Review - DNA History & Genetic Engineering

The term genetic engineering is best described as -

• Transferring genes from the genetic material of one organism to the genetic material of another organism

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

• Creating new DNA strands from old DNA strands

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

In the Midwest, corn has been altered to grow larger ears and be more drought tolerant. What is this called?

• mutation

• punctuated equilibrium

• genetic engineering

• gradualism

Identify the major goal of the Human Genome Project.

• Identify the approximately 20,000-25,000 genes in Human DNA

• prepare information for forensic shows on TV (CSI)

• discover the function of every human gene

• begin the process of cloning humans

All of the following, except one, are true statements about genetic engineering. Identify the false statement.

• Genetic engineering offers benefits, with no risks to society.

• Genetic engineering is used to increase food production.

• Genetic engineering can make plants more insect-resistant.

• Genetic engineering can reduce the amount of chemical pesticide needed for crops.

The process of cloning involves -

• breeding a plant or animal by artificially uniting an egg and sperm.

• creating a new cell, a group of cells, or an organism from a single ancestor.

• breeding a mixture of two different but related species

• combining either two eggs or two sperm together to produce a new organism

Which scientists were the first to develop an accurate model of the DNA molecule?

• Rosalind Franklin & Gregor Mendel

• Robert Hooke & Anton van Leeuwenhoek

• Gregor Mendel & Walter Sutton

• James Watson & Francis Crick

Rosalind Franklin created the above X-ray to examine the -

• division of DNA

• alleles of DNA

• structure of DNA

• chromosomes of DNA

Who is often referred to as the "Father of Genetics?"

• Rosalind Franklin

• Anton van Leeuwenhoek

• Charles Darwin

• Gregor Mendel

What is NOT an example of DNA technology currently used in agriculture?

• The development of frost resistant crop plants

• The use of growth hormones produced from recombinant bacteria to increase milk production

• The development of pesticide resistant crop plants

• The cloning of human nerve cells from corn plants

Which statement describes the process of cloning?

• Cloning is the creation of a new type of organism by artificially uniting an egg and a sperm.

• Cloning occurs by mating two different species.

• Cloning is the creation of a genetically identical copy of a cell or organism.

• Cloning is the creation of a new species of cell or organism.
