Question #1

Genes exist in pairs in individuals; during the production of gametes, the pairs are separated so that the resulting gamete has only one of each kind gene. This is known as:

A. Principle of segregation

B. Mitosis

C. Independent assortment

D. Meiosis

Question #2

Which of the following is a potential application for stem cells?

A. Replacing damaged cardiac muscle tissue after a patient suffered a severe heart attack.

B. Cloning hair follicles to use for hair transplant surgery.

C. Cloning prized agricultural livestock to use in breeding programs.

D. Helping endangered species survive by cloning members that have passed on.

Question #3

In biology, a clone of an individual or an identical twin of another are one of the same from a genetics point of view.

A. FALSE

B. TRUE

Question #4

In the meiotic process, the distribution of genes does not influence the distribution of other genes. In other words, one gene is not linked to another gene [Example: Albinism and blood type A are not linked as one can have albinism and blood type B, O or AB as well]. This is known as the:

A. Unification theory

B. Principle of segregation

C. Principle of Independent Assortment

D. Non-disjunction

Question #5

The end result of mitosis in humans is:

A. 2 cells with 23 chromosomes each

B. 2 cells with 46 chromosomes each

C. 4 haploid cells

D. 2 cells with mutations

Question #6

Which of the following is a Mendelian trait?

A. Eye color

B. Albinism

C. Height

D. Skin color

Question #7

It takes four nucleotide bases to code for a single amino acid.

A. FALSE

B. TRUE

Question #8

A Change in one base in a DNA sequence is called:

A. Crossing-over

B. Mutation

C. Transcription

D. Translation

Question #9

During a crime scene investigation, a victim was found unconscious and severely injured. There was blood all over the place. A team of forensic anthropologists collected blood samples from the various pools found. There was even a small sample left near an exit doorway which would not have likely been of the victim because of the proximity away where his body and blood was found. With such a small sample being enough for testing DNA one time, what should the investigators do?

A. Nothing needs to be done with a sample so small as there were bigger samples to test.

B. Amplify the sample by using the polymerase chain reaction technique so that there is more of the sample available for multiple tests.

C. Test the DNA of the small sample carefully to rule out that it was from the victim

D. Blood is blood, it all looks the same. It is not like fingerprints.

Question #10

DNA (deoxyribonucleic acid) is a sequence made up of combinations of how many different types of nucleotide bases?

A. 3

B. 4

C. 1

D. 2

Question #11

The mitotic process of a cell occurs_____________________.

A. at the same time as protein synthesis

B. before DNA needs to replicate

C. when there is injury to the skin and the healing process is taking place

D. in two cell divisions

Question #12

Polygenic traits are known to be:

A. discontinuous

B. Discrete

C. Qualitative

D. Continuous

Question #13

Which of the following is the correct order of the process known as protein synthesis?

A. DNA “unzips” locally, Transcription, mRNA travels to ribosomes, Translation, proteins formed

B. Proteins formed, mRNA travels to ribosomes, Translation, DNA “unzips” locally, transcription

C. Transcription, proteins formed, mRNA travels to ribosomes, Translation, DNA “unzips” locally

D. mRNA travels to ribosomes, Translation, DNA “unzips” locally, Transcription, proteins formed

Question #14

When males and females of a species have different coloration, it is evidence of sexual dichromatism.

A. FALSE

B. TRUE

Question #15

An individual with PKU (phenylketonuria) at birth is destined to have developmental difficulties no matter what accommodations are made since it’s a genetic trait.

A. TRUE

B. FALSE

Question #16

PKU is a Mendelian trait.

A. TRUE

B. FALSE

Question #17

If homologous chromosomes or chromosome strands fail to separate during meiosis, then serious problems can arise. This failure to separate is called:

A. Linkage

B. Disjunction

C. Non-disjunction

D. Independent assortment

Question #18

A DNA strand contains many base sequences, but few are read in a cell’s active life span.

A. FALSE

B. TRUE

Question #19

Which of the following is a function of DNA?

A. Protein synthesis

B. Sexual selection

C. Immune responses

D. ATP (energy) production
