Flashcards in HEMA 2 LEC - Cytotechnology Deck (18):
1
Numeric abnormalities
– not a multiple of the haploid number
aneuploidy
2
ex of aneuploidy
ex. Trisomy, monosomy
3
– chromosome number higher than 46
polyploidy
4
ex of polyploidy
ex. Triploidy (3n), tetraploidy(4n) ,hypodiploid, hyperdiploid, high hyperdiploid
5
occurs after rearrangement of chromosomes
Structural Abnormalities
6
: portion of the chromosome is missing or deleted.
Deletions
7
Duplications:
portion of the chromosome is duplicated, resulting in extra genetic material.
8
In a _____, segments from two different chromosomes have been exchanged.
reciprocal translocation
9
A portion of the chromosome has broken off, turned upside down and reattached, therefore the genetic material is ..
Inversions:
10
Formed by the mirror image copy of a chromosome segment including the centromere.
Isochromosome:
11
A portion of a chromosome has broken off and formed a circle or ring.
Rings:
12
This can happen with or without loss of genetic material.
Rings:
13
technology that is used to analyse the physical and chemical characteristics of particles in a fluid as it passes through at least one laser.
flow cytometry
14
Cell components are fluorescently labelled and then excited by the laser to emit light at varying wavelengths.
flow cytometry
15
excitation happens by __ in FC
Laser
16
label of cell components in fc
fluorescent
17
characteristics analyzed by FC
physical and chemical
