Are repressive proteins involved in positive gene regulation?

In prokaryotes, a well-known activator protein is the catabolite activator protein (CAP), involved in positive control of the lac operon. In the regulation of gene expression, studied in evolutionary developmental biology (evo-devo), both activators and repressors play important roles.

Hope this helps! ^_^

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
