In your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. One rattlesnake has a mutation and cannot produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred? Normal: AATCGCTACGCACGTCAG Mutated: AATCGCCATGCACGTCAG

There is a difference in the 7th, 8th, and 9th letter of the mutated snake compared to the normal. Hope this helps.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
