Genetics Jeopardy4/24/2015

Round 1 Each question is worth 50

points

Question #1 All living organisms store certain information in

DNA. Which of the following organic bases is not found in DNA?A. ADENINE

B. CYTOSINE

C. GUANINE

D. URACIL

Question #2 Gene expression is regulated to control the

development of an organism. At any given time, only a fraction of the total number of genes is expressed. How is gene transcription regulated?A. mRNA contains a special sequence of nucleotides

called initiators that signal when to begin transcription.

B. A sequence of nucleotides is “dropped” from the DNA chain, signaling mRNA to begin transcription.

C. RNA polymerase binds only to promoters on DNA that indicate where to begin transcription.

D. DNA polymerase unzips the part of the double helix to signal where to begin transcription.

Question #3 Groups of genes that work together in

prokaryotes are called operons. What role does an operon have in a prokaryotic cell?A. An operon halts DNA replication.

B. An operon regulates gene expression.

C. An operon destroys foreign DNA.

D. An operon creates new DNA.

Question #4 DNA stores the information for an organism’s

proteins. Molecular biologists can manipulate DNA to change these proteins are expressed in an organism. How can manipulation of DNA be used to improve agriculture?A. DNA manipulation can help engineers design

better harvesting equipment

B. DNA manipulation can lead to increased crop yields

C. DNA manipulation can help scientists receive more grant funding

D. DNA manipulation can help meteorologists influence weather patterns thereby helping crops grow.

Question #5 The study of DNA began long before Francis Crick

and James Watson developed the double helix model of the DNA structure. The basic structure of the nucleotides, which make up a DNA molecule, was discovered in 1919 by Phoebus Levene. Levene discovered that nucleotides consisted of three parts. What are the three parts of every nucleotide?A. A nitrogenous base, a 5-carbon sugar, and a

phosphate group

B. A glycerol molecule and one to three fatty acids

C. An amino group, a carboxyl group, and a side chain called an R-group

D. Carbon, hydrogen, and oxygen atoms

Round 2 Each question is worth 150

points

Question #6 Proteins have an important role in producing the traits

of an organism. How does DNA guide the synthesis of protein?A. The DNA copies the sequence of amino acids found on

the mRNA and arranges then to form proteins which control the production of traits.

B. The DNA copies the sequence of nucleotide bases on the ribosomes. The ribosomes convert the nucleotide bases into proteins through respiration

C. The DNA transforms into RNA, which carries out the synthesis of proteins as specified by the ribosomes.

D. The DNA contains a sequence of nucleotide bases that specify amino acids that are used to synthesize proteins.

Question #7 Advances in DNA technologies have allowed

scientists to sequence small genomes such as that of viruses and bacteria. In 1990, scientists from the United States and from other countries began the Human Genome Project. The goal of the Human Genome Project is to-A. Create a new organism using human genetic

material

B. Find cures for the most common genetic illnesses in humans

C. Develop a world-wide fund to pay for genetic research in humans

D. Analyze the human DNA sequence

Question #8 Genes that carry traits passed from one

generation to the next are made of DNA. The components of DNA carry the information which specifies the traits in an organism. Which diagram shows the sequence in which the components are assembled to form a polypeptide that determines a trait?A. Amino acid-> nucleotide-> protein

B. Nucleotide-> amino acid-> protein

C. Protein-> amino acid-> nucleotide

D. Nucleotide-> protein0-> amino acid

Question #9 A change in the DNA sequence can occur

because of mistakes in the replication of DNA or because of effects from chemicals or radiation in the environment. These types of changes may or may not affect an organism’s phenotype, and they can be the source of genetic variation that eventually results in evolution. This change in the DNA sequence is called?A. Re-sequencing

B. Genetic drift

C. A mutation

D. Gene flow

Question #10 What is the process that takes place in DNA

translation?A. An mRNA attaches to a ribosome where tRNA

brings the proper amino acid that is added to a growing polypeptide chain

B. An mRNA removes an amino acid from a ribosome and adds the amino acid to a floating polypeptide chain

C. A tRNA attaches to a ribosome where a moving mRNA binds with tRNA and forms an amino acid

D. A tRNA removes an amino acid from an mRNA and attaches it to a ribosome, where the ribosome converts the amino acid into a polypeptide.
