Lecture 1 chlamydomonas as a model system - monday, Things to remember/note: we will probably be expected to say how we know chlamydomonas have more than one genome and explain why. Dna is present in the nucleus, as with every form of life and because. Chloroplasts; both of which have their own sets of dna that is used to produce protein and enzymes required for their normal function: photosynthesis does not only occur in chloroplasts. The synechosystis is photosynthetic but does not have a chloroplast: eukaryotes are bigger than bacterium due to a eukaryotes membrane bound organelles (that prokaryotes do not have) which take up space. Mitochondrial genome: in comparisons, note speci cation of genome size vs nuclear genome size, This is because genome size could refer to having a genome in mitochondria, chloroplast, etc. which the model being compared to chlamy will not, making the rest of the dna irrelevant (to the comparison at least)

In a population of small homeotherms (endotherms), a mutation arises that results in the inner mitochondrial membrane having fewer folds(see page 3). A scientist measures the total length of the membrane within 10 members each of the two different types of animals. He finds that in the less folded membrane (animal type LF) the length is at about one-third that of the more folded membrane (animal type MF).

Based on the above finding he would correctly predict which one of the following? Top of Form

a) Animal type LF is capable of producing more ATP than animal type MF
b) Animal type MF is capable of producing more ATP than animal type LF.
c) There is no difference in the amount of ATP produced by the 2 types of animals.
d) Glycolysis does not occur in animal type LF.
e) Glycolysis does not occur in animal type MF.

Which of the following observations provide the best evidence for the Endosymbiotic Theory of the origin of Eukaryotes?
