Multiple Choice Questions

Drag the appropriate tRNAs to the binding sites on the ribosome to show the configuration immediately before a new peptide bond forms. Note that one of the binding sites should be left empty.
  • E SITE (EMPTY) / P SITE (AUA WITH 3 PROTEIN) / A SITE (UCC WITH ONLY 1 PROTEIN)
  • The nuclear genome of eukaryotes contains genes from archaeans and from bacteria.
  • Phylogenetic trees may expand quickly to maximum width and then narrow over time.
  • the deposit had been gradually uplifted to its present location
Rank the species from most closely related to horseflies to most distantly related to horseflies. If two species are equally close in their relatedness to horseflies, overlap them.
  • The nuclear genome of eukaryotes contains genes from archaeans and from bacteria.
  • DNA coding for rRNA changes relatively slowly.
  • the deposit had been gradually uplifted to its present location
  • FLEA < HUMAN BODY LOUSE + KATYDID / MAYFLY + DRAGON FLY > SILVERFISH
For each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (Note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)
  • PFK = Cytoplasm onlyinsulin = ER > Golgi > outside cell
  • directional selection
  • E SITE (EMPTY) / P SITE (AUA WITH 3 PROTEIN) / A SITE (UCC WITH ONLY 1 PROTEIN)
  • the homolog has evolved more slowly in mice.
Drag the aliens and shared derived characters to their appropriate locations on this phylogenetic tree. Use only the blue labels for the blue targets and the white labels for the white targets.
  • An addition mutation and a deletion mutation.
  • SPRING TAIL > FOURTH EYE > SECOND TAIL > GRASPING HAND
  • horizontal gene transfer
  • Birds and dinosaurs and their common ancestor
