AP Bio Unit 6 Review 6.5-6.8

What are regulatory sequences and where are they located?

• They control the initiation of transcription and are located near the promoter region of a gene

• They control the initiation of translation and are located near the terminator region of a gene

• They control the initiation of transcription and are located near the terminator region of a gene

• They control the initiation of translation and are located near the promoter region of a gene

What is the function of enhancers in gene expression?

• They decrease the activity of a terminator

• They increase the activity of a terminator

• They decrease the activity of a promoter

• They increase the activity of a promoter

What is the phenotype of an organism?

• Observable characteristics such as physical appearance, behavior, and biochemistry

• The initiation of transcription in an organism

• Genetic material present in an organism

• The process by which genetic information is used to synthesize proteins

How can differences in gene expression be caused?

• Mutations in the DNA sequence, changes in the activity of regulatory proteins, or differences in the availability of certain ions or environmental conditions

• Mutations in the DNA sequence, changes in the activity of regulatory proteins, or differences in the availability of certain nutrients or environmental conditions

• Mutations in the DNA sequence, changes in the activity of regulatory proteins, or differences in the availability of certain molecules or environmental conditions

• Mutations in the RNA sequence, changes in the activity of structural proteins, or differences in the availability of certain molecules or environmental conditions

What is the purpose of gel electrophoresis?

• To analyze protein fragments based on their size and charge

• To separate DNA fragments based on their size and charge

• To combine DNA fragments based on their size and charge

• To analyze RNA fragments based on their size and charge

How do DNA fragments move through the gel in gel electrophoresis?

• Based on their temperature and density

• Based on their texture and weight

• Based on their color and shape

• Based on their size and charge

What can be seen when a gel is stained with a DNA-binding dye in gel electrophoresis?

• RNA fragments as bands, each representing a group of same-sized RNA fragments

• DNA fragments as individual molecules spread across the gel

• DNA fragments as bands, each representing a group of same-sized DNA fragments

• Protein fragments as bands, each representing a group of same-sized protein fragments

What is the potential benefit of biotechnology to society?

• Creation of new products, processes, or technologies in medicine, agriculture, environmental management, and industrial production

• Creation of new products, processes, or technologies for entertainment purposes only

• Creation of new products, processes, or technologies in non-biological fields

• Creation of new products, processes, or technologies for personal use only
