Selective breeding

Process by which desired traits of certain plants and animals are selected and passed onto their future generations

1

Hybridization

Crossing parent organisms with different forms of a trait to produce offspring with specific traits

2

Inbreeding

Process in which two closely related organisms are bred to have the desired traits and to eliminate the undesired ones in future generations

3

Transgenic organism

Organism that is generally engineered by inserting a gene from another organism

4

Bioinformatics

Involves creating and maintaining databases of biological information

5

Genetic engineering

Technology that involves manipulating the DNA of one organism in order to insert exogenous DNA

6

Gene cloning

Process in which large numbers of identical bacteria, each containing the inserted DNA molecules, can be produced.

7

DNA ligase

An enzyme normally used by cells in DNA repair and replication

8

Recombinant DNA technology

The newly generated DNA molecule with DNA from another source (fragments from gel and DNA fragments and another source)

9

Polymerase chain reaction

Once the sequence of a DNA fragment is known, this technique can be used to make millions of copies of a specific region or a DNA fragment

10

Gel electrophoresis

A process in which an electric current is used to seperate DNA fragments according to the size of fragments

11

DNA sequencing

Four reaction mixtures include unknown DNA fragment, primer, DNA polymerase, the four nucleotides, and a different tagged nucleotide
