Would a mutation in the DNA of a skin cell be passed on to an organism's offspring?

• Yes, because any change to the DNA is passed on to the offspring

• Maybe. Sex cells only use half of the body's genetic code. It might get the copy of a gene that wasn't mutated.

• No. Only mutations that occur in the gametes (sex cells) are passed on to the offspring

• Without knowing the animal, it would be hard to tell whether or not the mutation would be passed on.

What is occurring in this picture and what is being made?

• Translation - Protein

• Translation - mRNA

• Transcription - Protein

• Transcription - mRNA

Which are the four outcomes of a mutation? (multiple answers)

• 1.The protein is changed and does something different

• 1.The protein is changed and does the same thing – sort of.

• 1.The protein is changed and does something different

• 1.The protein is no longer made or does not function at all

• The DNA will dissolve into a puddle of goo.

Which of the following would result in a frameshift mutation?

• Insertions only
• Substitution only
• Deletion only
• Insertions and Deletions

True or false, the sea horse and giraffes both use DNA (Cytosine, Thymine, Adenine, & Guanine) for their genetic code.

• True

• False

How can a person's muscle cells have the same exact DNA sequences as their nerve cells even though the look and perform completely different?

• The two different cells become mutated

• The genome in each cell is regulated differently resulting in a different expression.

• They actually have different DNA in the two types of cells.

• The genome of the different cells changes
