Q

DNA micro array

A

Target jeans embedded in or attached to a glass or plastic chip to which labeled CDNA pieces from a clinical sample bind and fluoresce. Micro array, show patterns of gene expression and gene variance present.

Q

RNA interference

A

Introduction of a small interfering RNA molecule that binds to and prevents translation of a specific mRNA

18
Q

suppressor tRNA’s

A

Transfer RNAs that change, premature stop codes into amino acid coding codons

19
Q

transcription activator like effector nuclease technology

A

A genome editing method that uses a bacterial restriction enzyme to cut DNA across both strands

20
Q

transgenic organism

A

an individual with a genetic modification such as a gene from another species in every cell

21
Q

zinc finger nuclease technology

A

A genome editing technique that uses protein motifs called zinc fingers to bind specific DNA triplets enabling a nuclease to cut the DNA across both strands
