Tropomyosin is a protein found in both skeletal and smooth muscle, but the mRNA produced in each of these is different in composition even though they are transcribed from the same gene. This observation is explained by a mechanism in eukaryotic cells known as .

the cell theory states that all living things including animals, as well as plants, are made of cells.

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:

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
