BIO 111 PURDUE EXAM 1 TEST QUESTIONS WITH ACCURATE SOLUTIONS
Which process describes cell division in prokaryotic organisms?
binary fission
Disruption of the signaling of growth factors will directly affect which of the cell cycle check
points?
G1
Which of the following conditions is required to proceed from metaphase to anaphase?
seperase is active
Which two processes are most similar compared to each other?
meiosis II and mitosis
A cell starts with 40 chromosomes (20 homologous pairs). After meiosis I what is the
arrangement of chromosomes in each cell?
20 chromosomes; each with two nonidentical chromatids
Which of the following is true regarding chromosomes during different forms of cell
division?
None of the above are true
, At what point of cell division are the nuclei of cells undergoing meiosis first considered
haploid nuclei?
After telophase of meiosis I
A toxin that prevented the formation of vesicles inside of a cell would most disrupt which
process?
cytokinesis in plants
What do we mean when we use the terms monohybrid cross and dihybrid cross?
a dihybrid cross involves organisms that are heterozygous for two characters, and a
monohybrid cross involves only one
What was the most significant conclusion that Gregor Mendel drew from his experiments
with pea plants?
traits are inherited in discrete units, and are not the results of "blending"
Which of the following differentiates between independent assortment and segregation?
The law of independent assortment requires describing two or more genes relative to one
another
Two plants are crossed, resulting in offspring with a 3:1 ratio for a particular trait. What
does this suggest?
