Biol 189 Final Exam | Verified study set | Questions and
Answers | 2026 Updates
ATP - ANSWER- is the energy currency of cells
genetics - ANSWER- The study of physical inheritance among living things is
A, T, G, or C - ANSWER- The information used to make proteins is encoded by the four
bases
The result of an error in anaphase that failed to separate a pair of sister chromatids would result
in - ANSWER- One cell would have an extra chromosome, and one cell would lack a
chromosome
are aligned at the equator of a cell during metaphase - ANSWER- Chromosomes
during prophase - ANSWER- The chromosomes become visible and the nucleus starts to
break up
during anaphase - ANSWER- Sister chromatids are separating from each other
How do daughter cells at the end of mitosis and cytokinesis compare with the parent cell before
DNA replication occurs? - ANSWER- The daughter cells have the same number of
chromosomes and the same amount of DNA
an organism that would reproduce by binary fission - ANSWER- Bacteria
zygote - ANSWER- The fertilization of an egg by a sperm produces a cell called
The products of meiosis - ANSWER- four haploid cells
What is the result of recombination (crossing over) during meiosis? - ANSWER- It creates
chromosomes that are a new combination of paternal and maternal material
What is the result of independent assortment during meiosis? - ANSWER- Genetically
diverse gametes are produced
An autosome - ANSWER- is one of the non-sex chromosomes
A human egg - ANSWER- contains 22 autosomes and one X chromosome
phenotype - ANSWER- is the term for an observable trait of an organism
, Mendel crossed true - ANSWER- breeding pea plants and found?- the dominant trait
always appeared in the F1 generation, but it appeared in a 3:1 ratio of dominant to recessive in
the F2 generation
The Law of Segregation - ANSWER- states that differing characters in organisms result
from two alleles that separate in gamete formation, such that each gamete gets only one of the
two alleles
homozygous - ANSWER- When two identical alleles for a character are present, the
genotype is referred to as
Let S = smooth pea and s = wrinkled pea Y = yellow pea and y = green pea. What are the
different possible genotypes of the gametes produced by a plant that is heterozygous for both
characters? - ANSWER- SY, Sy, sY, sy
Crossing two pink snapdragons yields some seeds that produce red-flowering plants, some
seeds that produce white-flowering plants and some seeds that produce pink-flowering plants.
If this trait operates by incomplete dominance and the allele R represents red flowers and the
allele r represents white flowers, what genotype would a plant with pink flowers have for this
trait? - ANSWER- Rr
If a person is unable to clot blood properly - ANSWER- platelets are lacking
A heart murmur would be associated with - ANSWER- the malfunction of the
atrioventricular valves
The left atrium - ANSWER- chamber of the heart receives blood from the lungs
The tiny air sacs of the lungs are called - ANSWER- alveoli
Most of the oxygen in human blood is carried in - ANSWER- hemoglobin
What do hemophilia, Duchenne muscular dystrophy, and red-green color blindness have in
common? - ANSWER- They are X-linked
A pedigree is a representation of - ANSWER- a genetic family tree
What single attribute determines that a human fetus is male? - ANSWER- the presence of
a Y chromosome
If the sequence TCGTA was used as a template in DNA replication, what would be the sequence
of bases on the newly synthesized strand? - ANSWER- AGCAT
