Answer:
Cell copies its genetic material during the S-phase of the interphase during cell cycle.
Explanation:
- Cell cycle is broadly divided into two phases ; the interphase and the M-phase.
- M-phase is the dividing phase during which the karyokinesis and cytokinesis takes place.
- Interphase is the phase during which the cell prepares itself for division.
- It is further divided into G1, S and G2 phase.
- During G1 phase the cell prepares for DNA replication and the replication complexes assemble.
- The next phase is S-phase during which the DNA replicates itself and the genetic material in the cell doubles.
- The Next phase is G2 phase during which the DNA is scanned by DNA tepair complexes and errors in the replicated DNA are edited and repaired.
- At the end of G2 phase the cell prepares to enter M-phase.
the major difference between the position of producers and primary consumers in the food chain-
Primary consumers make up the second level of the food chain, while producers make up the third level of the food chain.
Primary consumers make up the last level of the food chain, while producers make up the first level of the food chain.
