Which best summarizes the role of DNA in the production of proteins?
DNA moves to the cytoplasm to build proteins

A student noticed that the freshwater plant, Elodea, produced bubbles when placed in direct light. What could the student most likely conclude?
Bubbles of carbon dioxide were produced as a result of photosynthesis.
Bubbles of oxygen were produced as a result of photosynthesis.
Bubbles of carbon dioxide were produced as a result of cellular respiration
Bubbles of oxygen were produced as a a result of cellular respiration
These diagrams show a variety of cells from the same organism. How can cells from the same organism have such different shapes and functions?
As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity.
Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.
During differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.
During differentiation, different types of cells produce proteins which destroy the nonactive DNA, leading to cell specialization.
The chemical colchicine disrupts cell division. Which cell process would most likely stop if colchicine were added to a culture of human liver cells?
mitosis
meiosis
crossing over
active transport

Which statement best explains why animals are considered heterotrophic?
They are able to produce food through the process of photosynthesis.

They are able to obtain nutrients by decomposing plant and animal tissue.
They are able to obtain nutrients by consuming other organisms or their products.
Which effect could a mutation in mRNA have on the production of proteins?
The protein produced will have a different identity.
The protein produced will have a coiled shape.
