How does dna differ from rna?
dna codes for proteins; rna codes for lipids.
rna is a double helix; dna is a single strand.
dna lacks sugars in its backbone; rna has the sugar ribose.
rna is inherited; dna is a temporary genetic message.
dna never leaves the nucleus; rna is in the nucleus and in the cytoplasm.

DNA never leaves the nucleus; RNA is in the nucleus and in the cytoplasm.

Explanation:

DNA and RNA differ from each other with respect to their structure, function, and location. DNA is always present in the nucleus and never leaves the nucleus.  

DNA replication and transcription also occur in the nucleus to form DNA and RNA respectively.

On the other hand, RNA is present in both the nucleus and cytoplasm. The mRNA leaves the nucleus and enters the cytoplasm to serve as a template in protein synthesis. The rRNA and tRNA are also present in the cytoplasm.  

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.
