BIOLOGY
Which nucleotides are purines? - CORRECT ANSWERS Adenine and Guanine
what nucleotides are pyrimidines? - CORRECT ANSWERS cytosine, thymine,
uracil
Guanine and Cytosine make what kind of bonds and how many? - CORRECT
ANSWERS 3 Hydrogen bonds
Adenine and thymine make what kinds of bonds and how many? - CORRECT
ANSWERS 2 Hydrogen bonds
What did Watson and Crick do? - CORRECT ANSWERS discovered the structure
of DNA (double helix)
What organism did Thomas Hunt Morgan study? why? - CORRECT ANSWERS
fruit flies, because they generated offspring quickly and abundantly, with
distinguishable phentotypes
What is Thomas Hunt Morgan known for discovering? - CORRECT ANSWERS
Genes are stored on specific chromosomes, sex chromosomes, and crossing-
over

One

BIOLOGY
What are the four systems of sex chromosomes? - CORRECT ANSWERS XX and
XY- humans and most animals
XX and X
ZW and ZZ
Haploid and Diploid- lots of insects
What is X-inactivation? - CORRECT ANSWERS X inactivation is when the X
chromosome compacts into a Barr body and genes within become
unexpressed. The Barr body lies along the nuclear envelope, and is more likely
in females.
What is nondisjunction? - CORRECT ANSWERS An error in cell division that
causes homologous chromosomes or sister chromatids to move to the same
side of the dividing cell
What is an aneuploidy? - CORRECT ANSWERS Abnormal number of
chromosomes.
What is polyploidy? - CORRECT ANSWERS extra sets of chromosomes
What is one common aneuploidy? - CORRECT ANSWERS Down syndrome,
trisomy on chromosome 21
What are possible sex chromosome aneuploidys? - CORRECT ANSWERS XXY,
XYY, XXX, XO (turner syndrome)

BIOLOGY
What is a deletion mutation? - CORRECT ANSWERS When one or more
nucleotides are lost (i.e., deleted)
What is a duplication mutation? - CORRECT ANSWERS a segment of a
chromosome is repeated
Which mutation is most likely harmful? - CORRECT ANSWERS deletion
What is inversion mutation? - CORRECT ANSWERS When a part of the
chromosome reverses direction
What is a translocation mutation? - CORRECT ANSWERS moves a segment
from one chromosome to another, nonhomologous one
what happens when translocation is bad? - CORRECT ANSWERS The zygote
will not grow
What are the exceptions to mendelian genetics? - CORRECT ANSWERS genetic
imprinting, organellar inheritance, and epigenetics
What is genomic imprinting? - CORRECT ANSWERS Similar to x-inactivation,
but smaller. A copy of a gene is turned off at the allele level
