Question

Question 1
A) What would be the result of a cytosine base being substituted for a thymine base in a DNA segment during DNA replication? (1 point)

The entire segment of DNA would be affected.

There would be no effect on the DNA.

The cytosine base would pair with adenine when the DNA was replicated.

The sequence could code for the wrong amino acid during translation.

Question 2
A) Which of the following best explains why a cell spends most of the time during the cell cycle in interphase?(1 point)

Growth of the cell and replication of DNA prepare the cell for division.

Interphase is the last stage before exiting the cell cycle.

Mitosis happens during this phase where the cell divides.

Protein synthesis reads each codon carefully to ensure accuracy.

Question 3
A) Which statement is the first step of protein synthesis?(1 point)

DNA unzips between the base pairs.

A ribosome attaches to the mRNA.

Amino acids are linked together with peptide bonds.

tRNA carries amino acids to the ribosome and attaches them to the mRNA strand.
Question 4
A) Which statement is true?(1 point)

Amino acids do not need to be assembled in a particular order.

The human body uses 20 amino acids to form all types of proteins.

Amino acids form a polypeptide chain via carbon-carbon bonds.

tRNA is attached to specific proteins in the cell’s cytoplasm.
Question 5
A) Which statement about cystic fibrosis is true?(1 point)

Cystic fibrosis affects a person’s ability to make normal red blood cells.

Carriers have an advantage over people who do not have the cystic fibrosis mutation.

Cystic fibrosis is caused by a frameshift deletion of one codon in the DNA molecule.

Cystic fibrosis is caused by a mutation in which a dominant allele replaces a recessive allele.

Question 6
A) What benefit does using the CRISPR technique have in creating GMOs?(1 point)

Diversity within species can continue to increase through crossbreeding.

CRISPR can result in infertile hybrids.

Precise traits can be chosen to produce viable organisms more quickly.

It eliminates all risk of mutation.

Question 7
A) What is the phenotype of a mouse that has the genotype Bb where B is the gene for black fur and b is the gene for brown fur assuming this gene follows a Mendelian inheritance pattern?(1 point)

fur with black hairs

fur with yellow hairs

fur with both black and brown hairs

fur with brown hairs

Question 8
A) A tall, heterozygous pea plant is crossed with another tall, heterozygous pea plant. What is the probability that an offspring will be a short plant?(1 point)

75%

50%

25%

0%
Question 9
A) Which of the following mutations would be most likely to have a harmful effect on an organism?(1 point)

an insertion of a cytosine base near the start of an exon

a substitution of a thymine for an adenine

a deletion of 3 bases near the center of a gene

a deletion of a guanine base near the center of an intron

Question 10
A) Which statement best describes why Punnett squares are useful?(1 point)

Punnett squares are used to predict how recessive alleles are inherited.

Punnett squares are used to predict how dominant alleles are inherited.

Punnett squares are used to predict all possible allele combinations and their frequencies in offspring.

Punnett squares are used to predict the most likely allele combinations of the parents in a cross.

viral DNA or RNA copied by a host cell
A provirus is viral DNA incorporated into the host cell’s DNA.
It possesses a viral genome that mutates very quickly.
It copies the information for reproduction from RNA back into DNA.

Answer 19

A study shows that people who exercise outside are more likely to develop DNA mutations in their skin that lead to skin cancer. Which statement about exercising outside and skin cancer is correct?(1 point)

Exercising outside causes skin cancer.
Exercising outside causes skin cancer.

Exercising outside is correlated with an increased incidence of skin cancer.
Exercising outside is correlated with an increased incidence of skin cancer.

Skin cancer is correlated with an increased incidence of DNA mutations.
Skin cancer is correlated with an increased incidence of DNA mutations.
