Flashcards in 9- Biotechnology And Gene Manipulation Deck (13):
1

Autoradiography

A technique that uses film sensitive to radiation, most commonly X rays, to visualise the molecule(s) fragments that have been labelled with a radioactive isotope.

2

Genetic engineering

Techniques using recombinant DNA to produce organisms with different genes

3

Genetic fingerprint

A process that is able to identify natural variations that exist within everyone's DNA, using the polymerase chain reactions and gel electrophoresis

4

Genome

The total DNA of the haploid Ste of chromosomes in a na organism

5

Plasmid

A piece of DNA found in bacteria and yeast that is able to replicate independently of the main chromosomes of the cell.

6

Recombinant DNA technology

Transferring a gene from a cell of a member of one species to the cell of a different species

7

Stem cells

Unspecialised cells with the potential to develop into many different types of cells.

8

Amplification

Unknown

9

Biotechnology

The branch of science that deals with the manipulation of biological processes

10

Blunt end

Ends produced when restriction enzymes cut down DNA at the same position on both anti-parallel strands, leaving no overhanging edges.

11

Denaturing (DNA)

The process of heating up DNA which cause the hydrogen bonds between the bases to break leaving the two stands apart.

12

DNA ligase

An enzyme that synthesises bonds between adjacent nucleotides.

13

DNA polymerase

The enzyme used that catalysed the assembly of fragments of DNA
