Question 21 (1 point) Based on what we learned, what is true about E. Coli DNA replication? The polymerase activity of both DNA polymerase I and III is 5' 3'. DNA polymerase lII has a lower processivity than DNA polymerase I. For the leading strand synthesis, the DNA polymerase needs to keep loading new B-sliding clamps. DNA synthesis is continuous on the lagging strand and discontinuous on the leading strand. DNA polymerase III does not require a primer to start DNA replication.

Nitrogen metabolism

Nitrogen metabolism is the synthesis, utilization or uptake, breakdown, and excretion of nitrogenous compounds in the body. The nitrogen metabolism encompasses nitrogen fixation, biosynthesis, and the breakdown of amino acids, purines, and pyrimidine. Since nitrogen-containing compounds are required for various life processes, nitrogen is an important element of life.
