Update ) with Verified Answers
100 % Correct [Grade A]
Centrosome - correct answer a region of the cell that functions to organize
microtubules for cell division.
Composed of several filaments and micortubule fibers, with a pair of centrioles located
in the center of the centrosome.
Centrioles - correct answer a short, cylindrical protein filament composed of tubulin
that plays a role in the formation of the mitotic spindle.
M-phase consists of what 5 subphases? - correct answer 1) Prophase
2)Prometaphase
3) Metaphase
4) Anaphase
5)Telophase
,Cyclin - correct answer a protein that fluctuates in concentration at different phased of
the cell cycle.
How are cyclins named? - correct answer They are named after the phase in which
they are associated.
Gregor Mendel - correct answer an austrian monk who is credited for uncovering
genes and the fundamental principles of inheritance while working with pea plants
(1830's - 1880's)
True-Breeding - correct answer these plants will continue to display the same
characteristics as the parent plant over several generations of offspring.
Hybridization - correct answer when two true-breeding plants are crossed.
Alleles - correct answer different versions of the sae genes (human eye color, blood
type, etc.)
, monohybrid cross - correct answer when only a single trait is being studied during a
cross.
How does Cystic Fibrosis occur? - correct answer Cystic fibrosis results from a mutation
in the Cystic Fibrosis transmembrane conductance regulator gene (CFTR) on the long
arm (q-arm) of chromosome 7.
Compare and contrast purines and pyrimidines provide examples of each - correct
answer Purines contain two carbon-nitrogen rings and four nitrogen atoms (Adenine
and Guanine)
Pyrimidines contain one carbon-nitrogen ring and two nitrogen atoms (Thymine and
Cytosine)
Describe the structure and arrangement of DNA - correct answer DNA is a double
helix, which means it is composed of two helical strands. The two strands are held
together by the 'rungs', which are made of complementary pairs. The pairs are held
together by weak hydrogen bonds.
