What is the purpose of DNA?

• manufactures proteins

• to aid in facilitated diffusion

• stores hereditary information

• reduces activation energy

DNA is typically found in cells in the form of a very long strand that is coiled many times and contains thousands or millions of nitrogen bases. Which term best describes this very long molecule of DNA?

• gene

• nucleotide

• allele

• chromosome

The sequence of ________________ in a DNA molecule determines the protein that will be produced.

• sugars

• nucleotides

• lipids

• proteins

A segment of DNA that codes for the ability to make one type of protein molecule is known as a(n)____________________

• codon

• axon

• gene

• intron

Which is an example of a chemical change that occurs as part of the rock cycle?

• lava cools and condenses on the Earth's surface

• igneous rocks are cracked and broken into smaller pieces by weathering

• sedimentary rocks are turned into metamorphic rocks by heat and pressure

• sedimentary rocks are worn away by water erosion

Which of these would be caused by a chemical change?

• Sedimantary rock layering over time.

• Metamorphic rock eroding to form sedimentary rock.

• Metamorphic rock forming from igneous.

• The formation of lava.
