Document Summary

Biol 005a lecture 24: biotechnology, molecular tools used in biotechnology. Selective breeding : the process by which desired traits of certain plants and animals are selected and passed on to their future generations. Breed only those plants or animals with desirable traits. People have been using selective breeding for thousands of years with farm crops and domesticated animals. Hgp = map of all 30,000 genes on the 46 human chromosomes (1988-2003) Information has led to many advances in the fields of medicine, agriculture and bio-engineering. An organism"s genome is the total dna in the nucleus of each cell. Biotechnology refers to technology used to manipulate dna. The procedures are often referred to as genetic engineering. Dna is the genetic material of all living organisms. All organisms use the same genetic code (a,t,c,g)\ Can be used for creating transgenic organisms, gene therapy, and cloning. Recombinant dna refers to the dna from the two different organisms.

What is the difference between genetically-modified and transgenic crops?

Transgenic crops are a type of genetically-modified crops, in which scientists have inserted genes from another species.

Transgenic crops are illegal, while genetically-modified crops are not.

Genetically-modified crops are produced using modern techniques, while transgenic crops are produced through classical breeding.

They are the same.

Genetically-modified crops are a type of transgenic crop specifically bred for high yield.

Vavilov hypothesized that in a crop plant's area of origin we should expect:

Lower genetic diversity than in areas outside of the plant's area of origin.

Greater genetic diversity than in areas outside of the plant's area of origin.

Greater diversity for trans-domesticated species, but lower diversity for species domesticated in their area of origin.

Greater herbivore damage because of increased genetic diversity.

Lower diversity for trans-domesticated species, but greater diversity for species domesticated in their area of origin.

In what way did Harlanâs theory give rise to Diamondâs theory?

It recognized that agricultural societies were healthier and better fed than hunter-gatherer societies.

It recognized agriculture might have developed by different mechanisms in different parts of the world.

It is a basic case of scientific plagiarism - Diamonds theory is identical to Harlans theory.

It recognized the reason agriculture did not develop in certain parts of the world was because people lacked the intelligence or skill.

Both make the assumption that hunter-gatherers were (and still are) superior to agriculturists.

-----------

What is the difference between classically bred varieties and landraces?

Landraces are grown in dry conditions; classically bred crops are wetland species

Landraces cannot be harvested using domesticated animals; classically bred crops can be harvested using domesticated animals.

Landraces are often (though not always) developed by unintentional processes; classically bred crops are developed by intentionally breeding for desired traits using modern techniques

Landraces are not edible by humans; classical bred crops can be eaten

Landraces have no means of seed dispersal; classically bred crops can readily disperse their seeds

The inability of plants to move makes it difficult for them to:

Defend themselves.

Disperse seeds.

Create oxygen.

Disperse seeds, defend themselves, and create oxygen.

Disperse seeds and defend themselves.

Norman Borlaug won the 1970 Nobel Peace Prize for:

Producing the first transgenic plant.

His discovery that plant secondary metabolites play a role in defending plants from insects and diseases.

His work to create improved, high yield crop varieties that helped to prevent starvation.

Creating the FlavrSavr tomato.

His discovery of the area of origin for maize.

If a plant can grow well all by itself in the wild, yet still retains desirable agronomic traits, the plant is ____________________.

In discussing the origin of agriculture, the term demographic stress refers to:

A higher incidence of religious practice in societies following the transition from hunting and gathering to agriculture.

Lower productivity of un-cultivated plants due to late-Pleistocene cooling.

Hobbes's assertion that hunter-gatherer groups did not posses the knowledge or skills to develop agriculture.

The situation where human populations are greater than the carrying capacity of the environment.

That the stresses on pre-domesticated plant species led to the development of traits that result in the "domestication syndromeâ

------------------

The repeated domestication of grasses (i.e., cereals) and legumes across the globe is likely because:

Human populations were often starving, and needed an additional food source

Only grasses, not legumes, were repeatedly domesticated

Both contain almost all of the amino acids our bodies need to build proteins.

Early technologies allowed early agriculturalists the ability to communicate with each other over long distances to discuss what plants were best for domestication.

Both already possessed all of the traits needed for domestication
