Semi-conservative replication, discontinuous synthesis, the starting point and direction of replication all need DNA polymerase, helicase and so on.

Differences in replication between prokaryotes and eukaryotes;

1, Eukaryotes are linear DNA, with multiple replication start sites, forming multiple replication fork, and DNA polymerase moves slower than prokaryotes. Prokaryotes are usually circular DNA with a single replication initiation site.

2. Eukaryotic DNA replication only occurs in S phase of cell cycle. Once replication is started, it will not be replicated until it is completed, and many copies of prokaryotes will be made at the same time.

3. Eukaryotic replicons vary in size and are not synchronized.

4. Prokaryotes have replication initiation sites composed of 9-mer and 13-mer repeats, while eukaryotic replication initiation sites have no fixed form.

Extended data:

Compared with prokaryotes, eukaryotes have nuclei, larger cells and faster growth. Eukaryotes are usually heterotrophic microorganisms, which can derive a variety of organic acids in the process of growth and reproduction, and are easy to form complexes with metal ions in the process of ore leaching, which is beneficial to the leaching of valuable metals.

Prokaryotic cells can carry out aerobic respiration. Some prokaryotes, such as nitrifying bacteria and rhizobia, have no mitochondria, but contain a full set of enzymes related to aerobic respiration, which are distributed in the cytoplasm matrix and cell membrane, so these cells can carry out aerobic respiration.

Some prokaryotes, such as methanogens, have no enzymes related to aerobic respiration and can only breathe anaerobic. In short, most prokaryotes can carry out aerobic breathing.
