Question

Multiple choice: Suppose eukaryotes evolved by merging with bacteria to form composite cells by intracellular endosymbiosis in which one cell internalizes another that grows within it. Also, genes within the mitochondria should follow prokaryotic genetic principles. A common mitochondrial gene involved in electron transport chain known as cytochrome c, cox, which has protein coding sequence that is 420 bp in length starting from ATG to TAA. What would the length of the putative amino acid of the cytochrome c enzyme?

a. 420
b. 120
c. 119
d. 118
e. 121
