1) What is the name of the company or institution that has access to the health,
genealogical, and genetic information of approximately 270,000 residents of Iceland?
A) National Institutes Of Health
B) Decode
C) Gattaca
D) Biogen
E) American Cancer Society
ANSWER: B)
Rationale:
B) decode is the correct answer because it is the company that has been involved in
collecting and analyzing genetic information from the residents of Iceland, as part of a
large research project.
A) national institutes of health (NIH) is a U.S. Government agency focused on medical
research, not directly involved in collecting Icelandic residents' data.
C) Gattaca is a fictional company from the movie "Gattaca," which is unrelated to real-
world genetic research.
D) Biogen is a biotechnology company, but it primarily focuses on neurological
diseases, not the collection of genetic data from Icelandic residents.
E) American cancer society is a nonprofit organization focused on cancer research and
advocacy, not genetic information from Iceland.
2) A biotechnology company, decode, is in the process of creating a database that
contains ______.
A) the gene sequences of all newborns in the United States beginning in 2006
B) a compilation of all the known genes in humans throughout the free world
,C) health, genealogical, and genetic information of approximately 270,000 residents of
Iceland
D) a complete sequence of the human genome
E) all the information available on the human genome project
ANSWER: C)
Rationale:
C) decode is building a database containing health, genealogical, and genetic
information from Icelandic residents, focusing on the Icelandic population's unique
genetic background.
A) refers to a hypothetical scenario but is not accurate for decode's project, which is
specific to Iceland.
B) is too broad. Decode's database is not about every gene worldwide, but rather
focuses on the Icelandic population.
D) refers to the human genome project, which has completed sequencing the human
genome but is not specific to decode’s database.
E) refers to the human genome project, not decode's specific database, which is more
focused on genetic data from a specific population.
3) Why did decode select Iceland for its ambitious research project?
A) a relatively low degree of genetic diversity
B) frequent and extensive mutational bursts
C) high genetic diversity
D) lack of genealogical information
E) virtual absence of mutation
ANSWER: A)
Rationale:
A) a relatively low degree of genetic diversity is the correct answer because iceland’s
population is relatively homogenous, with fewer genetic variations, which makes it
,ideal for genetic research and identifying connections between genetics, disease, and
inheritance.
B) frequent mutational bursts are not the reason iceland was selected; iceland is
known for its genetic stability.
C) high genetic diversity would have made it more difficult to trace hereditary patterns
and genetic markers in a population.
D) iceland has extensive genealogical records, not a lack of them.
E) the presence of mutations in iceland’s population is typical and not absent, so this is
not the reason for the selection of iceland.
4) The genetic material DNA consists of basic subunits called ______.
A) mitochondria
B) lysosomes
C) centrioles
D) nucleotides
E) none of the answers listed is correct.
ANSWER: D)
Rationale:
D) nucleotides is correct. DNA is composed of nucleotides, which consist of a sugar,
phosphate group, and a nitrogenous base (adenine, thymine, cytosine, guanine).
A) mitochondria are organelles responsible for energy production, not basic units of
DNA.
B) lysosomes are organelles involved in digestion and waste removal, not involved in
DNA structure.
C) centrioles are structures involved in cell division, not part of DNA.
E) this is incorrect since nucleotides are the correct basic subunit of DNA.
5) The immediate product of transcription is ______.
A) a phospholipid
, B) an amino acid
C) a protein
D) a carbohydrate
E) RNA
ANSWER: E)
Rationale:
E) RNA is correct. Transcription is the process where DNA is used to synthesize
messenger RNA (MRNA), which is the immediate product.
A) phospholipids are not involved in transcription, which deals with RNA.
B) amino acids are the building blocks of proteins, but they are not produced directly
by transcription.
C) proteins are synthesized in translation, not transcription.
D) carbohydrates are energy molecules, not products of transcription.
6) In many species, there are two representatives of each chromosome. In such species,
the characteristic number of chromosomes is called the ______ number. It is usually
symbolized as ______.
A) haploid; n
B) haploid; 2n
C) diploid; 2n
D) diploid; n
E) none of the answers listed is correct.
ANSWER: C)
Rationale:
C) diploid; 2n is correct. In species with two representatives of each chromosome, the
total number of chromosomes is diploid, represented by 2n.
A) haploid refers to a single set of chromosomes (n), not two sets.
