Nova Lab Mission 3 Study Guide.

For a mutation to affect evolution, it must:

• Provide a benefit to the organism.

• Involve more than one chromosome.

• Be able to get passed from parent to offspring.

• Be neutral-neither help nor harm the organism.

What distinguishes bacteria from archae?

• Archaean DNA is made up a different set of nucleotide bases than is bacterial DNA.

• All archaea live in extreme enviornments, and bacteria don't.

• All archaea are unicellular, and some bacterial are multicellular.

True/False? "The change from a T to a C at position 3 caused all of the changes that exist between the cichild and colelacanth/frog."

• True, because that is the only column that has a change between positions.

• False, because more mutations can come later on.
