Question from campbell biology chapter 16:
grains represent radioactive material within the replicating eye.
47) in an experiment, dna is allowed to replicate in an environment with all necessary enzymes, datp, dctp, dgtp, and radioactively labeled dttp (³h thymidine) for several minutes and then switched to nonradioactive medium. it is then viewed by electron microscopy and autoradiography. the figure above represents the results.
which of the following is the most likely interpretation?
a) there are two replication forks going in opposite directions.
b) thymidine is only being added where the dna strands are furthest apart.
c) thymidine is only added at the very beginning of replication.

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?
