| DNA consists of Thymine, Cytosine, Guanine, and Adenine which differs from RNA because it has all with the exception of one that is substituted for this... | Uracil instead of Thymine |
| DNA has......sugar | dioxyribose |
| RNA has.....sugar | ribose |
| transcription occurs in what part of the cell? | the nucleus |
| mRNA is the......RNA | messenger |
| From the nucleus, the mRNA transcript moves into the..... | cytoplasm |
| translation occurs in the..... | cytoplasm |
| the RNA message is translated into.... | polypeptides |
| this picks up the appropriate amino acids and recognizes the appropriate mRNA | tRNA |

| what is the 4th thing that differs animals from other kingdoms? | body segmentation |
| what is the 5th thing that differs animals from other kingdoms? | embryology |
| how do the characteristics of the animal phyla relate to what we as humans have? | symmetry= bilateral, gut= complete digestive tract, body cavity= coelum, segmentation= specialized segments, embryology= deuterostomes |
| what are the 3 phyla of worms? | platyhelminthes, nematoda, annelida |
| give an example of the 3 phyla of worms | nematoda= roundworm, platyhelminthes= flatworm, annelida= segmented worm |
| what phyla of worm has bilateral symmetry, a nervous system w/ a brain, complex organs, a closed circulatory system, and segmented body parts? | annelida (ex.- earthworms and leeches) |
| what is the main advantage of the amniotic egg? | it allowed reptiles to continue their reproduction out of the water..and allowed evolution from fish:amphibians:reptiles to occur |
| what is the first step of the Hardy-Weinberg theory for genetic equilibrium? | must be a large population in size |
