adv. bio. chromosome Test Flashcards
(31 cards)
highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus
Chromatin strands
the reproducible patterns of dark and light bands
G-banding
measures specific proteins found in the blood of a pregnant women (“testing”)
Screening
miscarriage risk of 1% or less/a device to locate the fetus and identify a safe entry point for the needle
Ultrasound
may indicate a particular cancer/how fast the cancer spreads
Metastasizes
mistake
Anomaly
standard representations for chromosomes
Ideograms
the maternal and paternal chromosomes of a pair
Homologous Chromosomes
sex cells
Gametes
DNA wraps around scaffolding proteins
Histones
wrapped histones are then coiled into larger groups which stack together to form chromatin strands
Nucleosomes
father sperm
Paternal
2 copies of each chromosome
Sister chromatids
very close to the center and with arms of almost equal lengths
Metacentric
not far off the center
Submetacentric
far off the the center (p arm is very short)
Acrocentric
protective tip on a chromosome
Telomere
is an organized profile of an individual’s chromosomes
Karyotype
identifies each one, and confirms that its structure appears normal
Cytogeneticists
three complete sets of 69 chromosomes
Triploidy
is an abnormality that occurs when a piece of a chromosome is missing
Microdeletion
subunit of DNA
Nucleotides
each set of chromosomes includes one sex chromosome and 22 other chromosomes (body cells)
Autosomes
Male has XY and Female has XX
Sex chromosome
