STEP 1 Review the imaginary strand of DNA below. Note the complementary base pairs. AGCAATCCGTCTTGG
TCGTTAGGCAGAACC

STEP 2 To begin replicating this strand of DNA, draw the two sides of the strand separating.

STEP 3 Now, draw the free-floating bases linking up with the separate sides. Remember to
follow the rules of complementary base pairing.

STEP 4 Draw the two resulting DNA strands.

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?

Ecology can best be described as the study of what
