Ethics

4

The study of the ethical issues of biological research and applications, especially in medicine

Bioethics

5

The technique of managing biological systems for human benefit

Biotechnology

6

The science of improving the qualities of a breed or species by different strategies, such as the careful selection of parents or the use of genetic testing

Eugenics

7

The chemical inside the nucleus of a cell that carries the genetic instructions for making living organisms

DNA

8

What are the tools of molecular biology

DNA extraction, cutting DNA, separating DNA, reading the sequence, cutting & pasting, and making copies

9

What is DNA extraction

The cells are opened and the DNA is taken out

10

What is done in cutting DNA

When the DNA is to large to be analyzed the scientists cut it into smaller pieces

11

What is separating DNA

Scientists use gel electrophoresis

12

What is done in reading the sequence

Scientists read the bases and determining the order

13

What is done in cutting & pasting

Scientists change the strands by cutting old strands and replacing them by pasting new ones

14

What is done in making copies

Scientists copy a strand

15

What are some risks of genetic engineering

Birth defects, new diseases, and antibiotic resistance

16

What are some benefits of genetic engineering

Disease resistance plants, better vaccines, and you can remove hereditary diseases

17

What allows only the animals with desired characteristics to produce the next generation

Selective breeding

18

What happens when you cross dissimilar individuals to bring together the best of both organisms

Hybridization

19

What is the continued breeding of individual with similar characteristics

Inbreeding

20

What is a member of a population of genetically identical cells produced from a single cell

Clone

21

The functional and physical unit of heredity passed from parent to offspring

Gene
