Q

what tests uses fluorescent dyes combines with multiple nucleotide probes to visualize specific genes or portions of genes in a cell

A

fluoresce in situ hybridization (FISH)

17
Q

what are some examples of how FISH testing is used

A

screening for cancer
screening for HIV
prenatal diagnostic testing

18
Q

what is the importance in FISH testing

A

it can test for specific biomarkers in solid and hematological neoplasms

19
Q

what are some advantages of autoradiograph

A

provides high sensitivity and resolution
can be used to analyze the length and number of DNA fragments after they are separated from one another by gel electrophoresis

20
Q

what are some advantages of expansion microscopy

A

chemicals are inexpensive
can be used with ordinary microscopes
superior resolution
expansion capability up to 20 times

21
Q

what is the purpose of anchoring in expansion microscopy

A

reagents bind the proteins or molecules of interest to the probes with fluorescent label

22
Q

what is the purpose of technical homogenization in expansion microscopy

A

the ultrasonic homogenizer and proteinases digests or breaks-down the structural molecules of the cell to prepare the tissue to receive the expander solvent

23
Q

what can cause variances in resolution

A

type of optical system
wavelength
thickness of specimen
fixation
staining intensity

24
Q

what is the method of specimen illumination used for transmitted and reflected light optical microscopy that reduces light source interference

A

Kohler illumination

25
Q

what are some advantages of Kohler illumination

A

even illumination of sample
reduces image artifacts
provides high sample contrast

26
Q

when would you use a phase contrast microscope

A

when examining unstained cells or living cells

27
Q

what is a common microscopic technology used in pathology that transmits over mobile devices uses a slide scanner

A

virtual microscope

28
Q

which structure in the cell makes ribosomes

A

nucleolus

29
Q

what are the three components of the cell membrane

A

lipids
proteins
carbs

30
Q

what are the three purposes of linker proteins

A

provides structure to cells
helps to provide movement to cells
may link cells together

31
Q

what binds mRNA and tRNA

A
