NSG 530 EXAM 1 2026 QUESTIONS
AND ANSWERS | A+ GRADED | WITH
EXPERT SOLUTIONS
Interphase - correct answer-cell feeds, metabolizes and grows
while replicating DNA in preparation for mitosis
Prophase - correct answer-first appearance of chromosomes (will
be 92)
Metaphase - correct answer-Centrioles pull chromosomes to
opposite sides of cell (chromatid) - 46 each side
Anaphase - correct answer-Centromeres split and sister
chromatids are pulled apart
Telophase - correct answer-New nuclear membrane formed
around each group of 46 chromosomes *When it goes right,
euploid cells are produced*

Nondisjunction - correct answer-Error in meiosis in which
homologous chromosomes fail to separate.
Polyploidy - correct answer-condition in which an organism has
extra sets of chromosomes
Triploidy - correct answer-when an organism has three copies of
every chromsome instead of two
Tetrapoloidy - correct answer-euploid has 92 chromosomes and
fetus usually does not survive
Huntington's disease - correct answer-Single gene disorder
(trinucleotide repeat mutation)
Autosomal dominant (50% chance of passing it on)
Progressive neurologic disease with late onset (40s)
Prevention- genetic testing for pregnancy planning
