• two X chromosomes; X and Y chromosome

During gene therapy, bone marrow stem cells are removed from the individual. What must happen to those cells before they are injected back into the individual?

• The cells are treated with high doses of radiation to destroy any faulty genes. Then, viruses act as vectors to replace those faulty genes with normal ones.
• The DNA of the stem cells is removed completely and replaced with a new genome that carries the normal gene.
• The mRNA of the stem cells is completely removed and used to create new normal genes that are then injected into the nucleus of the stem cells.
• Viruses act as vectors to carry the normal gene into the genome of the stem cells.

Select all of the following statements that describe the structure of a molecule of DNA.
Check All That Apply

• twisted double helix twisted double helix
• single-stranded single-stranded
• contains the nitrogenous bases, adenine, thymine, cytosine, and guanine contains the nitrogenous bases, adenine, thymine, cytosine, and guanine
• contains deoxyribose sugar contains deoxyribose sugar
• contains the nitrogenous bases adenine, uracil, cytosine, and guanine

Which of the following best describes the overall goal of transcription?

• To edit the mRNA strand and make it ready to leave the nucleus.
• To create a mRNA copy of a segment of DNA to take outside the nucleus.
• To retrieve amino acids and bring them to the ribosome for assembly into a polypeptide.
• To unpackage and unwind DNA so that enzymes can access the individual genes.

True or False: Gene therapy has been used for years to treat or cure sickle-cell disease.

• False
• True

DNA replication is considered to be _____ because the end product consists of one old strand and one newly synthesized strand.

• semiconservative
• relaxed
• dispersive
• conservative
• stringent

Describe the movement of oxygen and carbon dioxide during gas exchange.

• Oxygen diffuses out of the lungs into red blood cells and carbon dioxide diffuses out of red blood cells and into the lungs.
• Oxygen diffuses out of the lungs into red blood cells and carbon dioxide diffuses out of red blood cells into the kidney nephrons.
• Carbon dioxide diffuses out of the lungs into red blood cells and oxygen diffuses out of red blood cells and into the lungs.

RNA polymerase has several jobs during the transcription process. Which of the following is not a job that it performs?

• RNA polymerase binds to the promoter region to start transcription.
• RNA polymerase makes a complementary mRNA strand by adding RNA nucleotides.
• RNA polymerase edits the mRNA strand by removing some sections and splicing together remaining sections.
• RNA polymerase unwraps small segments of DNA to expose the template strand to be transcribed.

Which of the following best describes how the environment may play a role in the expression of our genes.

• The environment is not able to alter genes or their physical expressions. Genotypes and phenotypes are both completely independent of environmental changes, unless in the form of mutations.
• All genes are directly influenced by the environment, even if only in minor ways, so the environment will always alter phenotype for all genes.
• Some phenotypes, including skin color, can be influenced by the environment. The genotype still determines some aspect of skin color, but the interaction with the environment, in the form of sun exposure, can cause variations in the resulting phenotype.
• The environment can alter an individual’s appearance, but because these changes are temporary and unable to be inherited, they have no impact on the genotype or the expression of that genotype.

Variations in genes are called _____. Examples of these variations include eye color. There are blue eyes, green eyes, brown eyes, and several combinations of these.

• traits

Familial hypercholesterolemia is a disease that is incompletely dominant. This means that

• multiple alleles exist for this trait, so multiple phenotypes are possible. In the case of familial hypercholesterolemia, heterozygotes can have a range of cholesterol levels depending on which combination of alleles exists.
• the dominant allele completely masks the recessive allele, so the dominant phenotype is displayed. In the case of familial hypercholesterolemia, heterozygotes will have extremely high levels of cholesterol, identical to those seen in homozygous dominant individuals.
• the dominant allele is equally dominant with a second (or third) dominant allele, so both phenotypes are displayed. In the case of familial hypercholesterolemia, heterozygotes have moderately higher levels of cholesterol compared to normal.
• the dominant allele does not fully mask the recessive allele, so an intermediate phenotype is displayed. In the case of familial hypercholesterolemia, heterozygotes have moderately higher levels of cholesterol compared to normal.

What is the role of the enzyme ligase in DNA replication?

Sickle-cell disease causes hemoglobin proteins to become altered. What direct effect does this have on red blood cells?

• Red blood cells swell up, allowing fewer to flow through tiny capillaries and reducing blood flow.
• Red blood cells become sickle-shaped, clumping up and blocking blood flow in capillaries.
• Red blood cells shrivel up, causing too many of them to flow through capillaries at once, increasing blood pressure.
• Red blood cells become sickle-shaped, resulting in them carrying increased oxygen to body cells. Hyperoxia results.

During translation, a polypeptide chain is created using a RNA template. Which of the following components is responsible for bringing amino acids to the growing polypeptide chain?

• tRNA
• mRNA
• rRNA
• ribosomes
• RNA polymerase

A single mutation causes sickle-cell disease. Which of the following statements best describes how this occurs?

• The addition of several nucleotides cause the start codon to shift down several places. This causes RNA polymerase to bind in the incorrect spot so that several extra amino acids are included in the polypeptide chain during translation. This results in a hemoglobin protein that is incorrectly formed, resulting in sickle-shaped red blood cells that cannot function as intended.
• Three nucleotide mutations cause normal glutamine amino acids to be replaced with valine amino acids. This causes excess hemoglobin proteins to be synthesized, causing red blood cells to swell to the point of bursting, resulting in burst cells that have a sickle-shape.
• The removal of several nucleotides cause the start codon to shift down several places. This causes RNA polymerase to bind in the incorrect spot so that several amino acids are left out of the polypeptide chain during translation. This results in a hemoglobin protein that is incorrectly formed, resulting in sickle-shaped red blood cells that cannot function as intended.
• A single nucleotide mutation causes a normal glutamine amino acid to be replaced with a valine amino acid. This causes the resulting hemoglobin protein to form incorrectly, resulting in sickle-shaped red blood cells that cannot function as intended.

• targeting and attacking faulty hemoglobin molecules within red blood cells, so that new normal molecules may take their places.
• targeting the mRNA produced during the expression of the hemoglobin protein, removing and replacing faulty portions with correct sequences.

Sickle-cell disease is a recessive genetic disease. This means

• only one copy of the recessive allele must be present in order for the disease to be expressed.
