In the article, How snakes lost their legs, what is the Sonic Hedgehog gene is responsible for?

• venom production

• skin pattern

• limb development

• sensory organs

The fossil records indicates that at one point in time, snakes had "legs". In the article, what is the role of DNA regulatory sequences called enhancers?

• monitor time of amino acid transfer into polypeptide chain

• control the way genes turn on and off for specific body parts

• regulate the amount of protein synthesis during a certain period

• to copy the DNA and produce the proteins coded in genes

Think about the article, "How snakes lost their legs". What did scientists discover had happened over time to the DNA sequence of the enhancers?

• the DNA sequence doubled

• parts of the DNA sequence were substituted

• the DNA sequence connected to the RNA sequence

• parts of the DNA sequence were deleted
