Chapter 15 genetics

Its main goals is sequencing all 3 billion base pairs of human DNA and identify all human genes

Farmers choose __________ because they produce higher yields, reducing the amount of land used

The process by which an absent or faulty gene is replaced by a normal, working gene

A piece of DNA is heated, which separates its two strands, this is which step in PCR?

Making copies of _______, would increase the food supply and could help save endangered species

This makes it possible to change the genetic composition of living organisms:

Scientists can use this technique to separate and analyze the differently sized fragments:

They can be produced by the insertion of recombinant DNA into the genome of a host organism:

Takes advantage of genetic variation to pass wanted traits to the next generation of organisms

The extracted DNA can be cut into fragments of manageable size using:

Roughly one fifth of the known genes in the human genome are now ________ commercially.

This biologist at Woods Hole Oceanographic Institute in Massachusetts, wanted to find GFP

A cell takes in DNA from outside the cell,that added DNA becomes a component of the cell’s own:

By using tools that replicate DNA scientists can now read the base sequences in DNA, used to:

Its main goal is to gain a better understanding of the nature of life.

Breeders often use________, the continued breeding of individuals with similar characteristics.

Used to study hundreds or even thousands of genes at once to understand their activity levels.

Method created crossing dissimilar individuals to bring together the best of both organisms:

Known as the application of a technological process, invention, or method to living organisms:

Once biologists find a gene, this technique allows them to make many copies of it:

Drugs that prevent the separation of chromosomes during meiosis are very useful in:

In addition to their chromosomes, some bacteria contain small circular DNA molecules known as:

Used to identify individuals by analyzing sections of DNA that may have little or no function

Harmless to humans and most other animals, but it converts into a form that kills the insects:

Which are the two more common methods of selective breeding?

Their goal is largely to develop profitable new crops, drugs, tests, or other products.

Is the source of some of the most important advances in the prevention and treatment of disease

Many bacteria produce_______that cut DNA molecules into precise pieces (restriction fragments)

How do people increase genetic variation?

Botanist that developed more than 800 varieties of plants using selective breeding methods:

This combines molecular biology with information science:

Today it is often quicker and less expensive for scientists to search for genes in computer:
