Beechdrops is a parasitic plant that cannot perform photosynthesis but relies on its host the Beech tree. However, Beechdrops still retains many if not all of the genes for photosynthesis
Snapdragons and gladiolas are common garden flowers that rely on their ability to perform photosynthesis. If you were to compare the gene sequences for these three plants for ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) a protein necessary for photosynthesis what would you predict? A. The differences between gladiolas and snapdragons would most likely be silent mutations while those in beechdrops may be silent or missense B. Since these three plants are not highly related the sequences for RuBisCO would be very different between them C. The differences between gladiolas and snapdragons would most likely be in the second nucleotide of codons while beechdrops would have a higher number of mutations in the third nucleotide of the diffferent codons D. The differences between gladiolas and snapdragons would most likely be missense mutations while those in beechdrops may be silent or missense
