DNA and Proteins |
#1 |
What are the base pairing rules |
Adenine - Thymine, Cytosine - Guanine |
#2 |
What are the 3 parts of a DNA nucleotide |
sugar (deoxyribose), nitrogen base, phosphate group |
#3 |
this is the area where the double helix separates during replication |
replication fork |
#4 |
what are the 3 ways RNA is different from DNA |
ribose instead of deoxyribose, single strand instead of double strand, uracil instead of thymine |
#5 |
what are the coding regions called |
exons |
Evolution |
#1 |
What have scientists noticed about all vertebrate embryos |
they are very similar early on |
#2 |
Give an example of a vestigial structure |
human tailbone, appendix, whale's lower limb |
#3 |
this is the process by which a species becomes better suited to its environment |
adaptation |
#4 |
this is the process by which organisms well suited to the environment survive and produce more offspring than those less suited |
natural selection |
#5 |
these are the 3 main pieces of evidence for evolution |
fossils, anatomy (vestigial and homologous structures), biological molecules (DNA and proteins) |
Classification and Mammals |

#2 |
this is the largest taxonomic group |
domain |
#3 |
this is the science of naming and classifying organisms |
taxonomy |
#4 |
what are the characteristics of mammals |
hair, 2 sets of teeth, endothermic, nurse their young |
#5 |
what is the function of hair |
insulation, sensory, defense (camolflauge) |
