When DNA is copied, sometimes a new, incorrect base-pairing appears within the structure of a new DNA molecule replacing original base pairs. This mistake is called a base-pair mismatch due to replication error. This is known as DNA damage.
These kind of mismatch errors can be corrected by DAM (DNA adenine methylation) repair system. This repair system recognizes one of the two mismatched nucleotide to be corrected by methylation pattern. The non-methylated DNA strand in the hemi-methylated DNA progeny is recognized as the strand to be corrected by DAM repair system.
Answer:
Biofuels have been around longer than cars have, but cheap gasoline and diesel have long kept them on the fringe. Spikes in oil prices, and now global efforts to stave off the worst effects of climate change, have lent new urgency to the search for clean, renewable fuels.
Our road travel, flights, and shipping account for nearly a quarter of the world's greenhouse gas emissions, and transportation today remains heavily dependent on fossil fuels. The idea behind biofuel is to replace traditional fuels with those made from plant material or other feedstocks that are renewable.
But the concept of using farmland to produce fuel instead of food comes with its own challenges, and solutions that rely on waste or other feedstocks haven't yet been able to compete on price and scale with conventional fuels. Global biofuel output needs to triple by 2030 in order to meet the International Energy Agency's targets for sustainable growth.

They share cellular respiration. Producers also photosynthesize (or chemosynthesize) and consumers do not.
They share cellular respiration but dint share photosynthesis
