BSCI222 EXAMS 1, 2, & 3 NEWEST VERSION
QUESTIONS AND ACCURATE VERIFIED ANSWERS
GRADED A+
How do you calculate the degrees of freedom for independent
assortment? -Correct Answer- the number of phenotypes minus one
How do you calculate chi-square values regarding Mendelian
Independent Assortment? -Correct Answer-(actual - expected)^2 /
expected summed for each phenotype
Why can DNA polymerase enzymes not start a new strand during
replication? -Correct Answer-They can only synthesize DNA if there is
an existing 3' OH to work off of
How does DNA replication work around the process of DNA polymerase
being unable to begin the synthesis of a new strand? Correct Answer-
They utilize RNA primers, which do not need an existing 3' OH to work
off of
Do prokaryotic genomes, eukaryotic genomes, or both have
chromosomes that must include an origin of replication sequence?
Correct Answer-both
Do prokaryotic genomes, eukaryotic genomes, or both have very little
sequence on the chromosome outside of genes? -Correct Answer-
prokaryotes
Do prokaryotic genomes, eukaryotic genomes, or both have the ends of
the chromosome protected by shelterin proteins? -Correct Answer-
eukaryotes
, Do prokaryotic genomes, eukaryotic genomes, or both usually have
more than one chromosome? -Correct Answer- eukaryotes
Do prokaryotic genomes, eukaryotic genomes, or both have the ability
for their DNA to be condensed through supercoiling? -Correct
Answerboth
What characteristic of a karyotype would show XO sex determination? -
Correct Answer- Presence of only one sex chromosome
How does calculating multilocus probability account for independent
assortment? -Correct Answer- Multiplying shows the events occur
separately
Which enzyme involved in DNA replication is inactive if, in a
prokaryotic cell, the replication bubble cannot open? -Correct Answer-
Initiator proteins (DNA A)
Which enzyme involved in DNA replication is inactive if, in a
eukaryotic cell, the replication bubble cannot open at one single origin
of replication? -Correct Answer-licensing factors
Which enzyme involved in DNA replication is inactive if, in a
prokaryotic cell, primers are left in the newly synthesized strand?
Correct Answer-DNA Polymerase I
Which enzyme involved in DNA replication is inactive if, in a
eukaryotic cell, primers are made by elongation from the primer does
not occur? -Correct Answer-DNA Polymerase Delta
Which end of the mitotic spindle fiber is positive? -Correct Answer- The
end that connects to the DNA/centromere
