Answer:
Genetic continuity is maintained by the Replication or Synthesis phase and the Mitosis phase of the Cell cycle.
Explanation:
- The Cell Cycle can be divided into the following phases,
- G0- Interphase.
- G1 - Growth phase.
- S - Replication or Synthesis phase.
- G2 - Second Growth phase.
- M - Mitosis.
- Of all the above phases, in the S phase the replication or doubling of the genetic material, that is, the DNA, occurs for equally distributing the genetic material to both the daughter cells.
- The M or the Mitosis phase is also essential to ensure that the distribution of the genetic material occurs accurately among the daughter cells.
- Hence, a genetic continuity is maintained across the generations of the cells.
Answer:
Operons can be used to coordinate the expression of multiple proteins in combination in the prokaryotes. An operon is a fundamental unit of DNA that transcribes, translates, or splices an array of genes under the guidance of a single operator and promoter.
The expression of genes can take place in combination or not at all. The regulation of operon can either be positive or negative due to repression or induction.
Answer:
I think B
Explanation:
Because it is not a physical weathering example, it is not based on the weather it is based on a growing plant.
