- Which of the following is an accurate point that supports the idea that the earliest protocells relied first on RNA (not DNA) as inherited information? A. RNA is composed of lipids, and lipids were present on early Earth before the nucleotides that compose DNA were B. RNA is a monomer (unlike DNA), so it is simpler and more likely to have been used by these simple protocells C. DNA would have been too large to fit into the small protocells, but RNA was small enough to fit D. RNA can serve dual roles as both genetic information storage and an enzyme (but DNA cannot do both) ..arrow_forwardWhat factors could be responsible for the size differences among modern vertebrate genomes?arrow_forwardDo plants and animals have a common multicellular ancestor?arrow_forward
- What evidence supports the hypothesis that mitochondria preceded plastids in the evolution of Eukaryotes cells?arrow_forwardIn the evolution of the eukaryotic cell, these cells have evolved key changes that include which of the following: a) These cells reproduce by copying their DNA perfectly each generation b) They have their DNA in the nucleoid area c) They have adapted the mesosome membrane system of the prokaryote to form a nucleus and an endoplasmic reticulum d) each new type of new eukaryote cell has its mRNA unchanged from its original mRNA e) none of these are truearrow_forwardIn a molecular phylogeny what can serve as a synapomorphy?   a.) amino acids       b.) homoplasy       c.) None of the answers are correct       d.) insertions       e.) orthologsarrow_forward
- With two specific examples, explain why phylogenetics is a useful scientific tool for studying Organismal biology?arrow_forwardWhat genes from the mitochondrion are also used for phylogenetic analysis? Can you name and describe atleast 2 genes?arrow_forwardGeneticists have determined the amount of DNA, the number of different genes, and the size of the cell/nucleus in a wide variety of model organisms. as we move up the phylogenetic scale, the amount of DNA/cell increases much more rapidly than does the volume in which that DNA must be packaged. How do higher organisms package their DNA in the interphase cell?arrow_forward
- Within the field of phylogenetics, what does a “bootstrap value” represent? (write/make 3 points for this question)arrow_forwardIf you are to compare the genetic sequences between monkeys and fungi, what molecular sequence are you going to use? Why? How about comparing genetic sequences of monkeys to humans, what genetic sequence will you use? Provide an explanation.arrow_forwardDo these phylogenetic trees tell the same story?arrow_forward
