Technologies

Question 1

Staining

Answer 1

Improves contrast in samples as the colour often binds differently to distinct parts of the sample

Question 2

Resolution

Answer 2

Ability to distinguish between two structures that are very close together

Question 3

Fluorescence Microscopy

Answer 3

type of spectroscopy in which fluorescing substances that exist on the surface will glow after being exposed to a uv light

Question 4

Confocal technology

Answer 4

Allows us to view living cells in three dimensions. A laser is used to light up sample

Question 5

GFP Technology

Answer 5

Utilizes a green fluorescent protein found in jellyfish, the protein can be attached to areas or organelles of interest within cells

Question 6

Electron Microscopy, TEM and SEM

Answer 6

Uses a beam of electrons instead of light to illuminate the specimen

TEM= Depends on beam of electrons passed through a thin section of fixed and strained tissue

SEM= Gives info about surface features of a specimen

Question 7

X-ray crystallography

Answer 7

Study of the structure of molecules by means of x-rays, special sensors that analyze patterns of x-ray scattering and computer technology (JJ thompson)
