Biology EOC Review

Which technique would most likely be used by forensic scientists?

• gene cloning

• gene therapy

• DNA fingerprinting

• karyotyping

In which populations does genetic drift most often occur?

• in small populations

• in large populations

This diagram shows a cladogram of six species based on amino acid similarities. Which two species are the most closely related?

• I and II

• II and IV

• I and V

• V and VI

This chart shows which amino acids are coded for by different combinations of mRNA nucleotides. Which amino acids are coded for by an mRNA segment that reads CAG GUG?

• arginine and valine

• isoleucine and arginine

• glutamine and valine

Which statement best describes the relationship that exists among proteins, DNA, and cells?

• Proteins combine to produce cells, which produce DNA.

• Proteins are made up of DNA, which determines the cells that are produced.

• DNA is made up of proteins, which tell a cell how to function.

• Cells contain DNA, which controls the production of proteins.

Two people believe they are related. Which would be the best technique to determine if they are related?

• testing blood types

• examining karyotypes

• comparing DNA

• testing for genetic disorders

What is the difference between the full classification of organisms and their scientific names?

• The full classification of organisms and their scientific names vary in different countries.

• The scientific names of organisms include the order and family of the organisms, but the full classification includes only the species name.

• The full classification of organisms will include more categories of organisms than their scientific names.

• The scientific names of organisms include a single nomenclature, but the full classification includes various nomenclatures.

Which is one reason scientists produce transgenic organisms?

• to create new species of organisms

• to control microorganisms in the soil

• to prevent habitats from being destroyed

• to treat certain types of diseases

What is the best explanation for the continual changes in the classification system of organisms?

• All organisms struggle for existence and become extinct.

• All organisms compete to be at the top of the food chain.

• Technological advances have allowed scientists to better compare organisms.

• More species have been discovered, but scientists have not analyzed all the data.

Which will most likely cause variations to occur within a species?

• competition

• mutation

• mutualism

• predation
