Answer:
C. repressible
Explanation:
The trp operon in bacteria is a repressible operon. The regulatory gene codes for repressor protein. In the presence of tryptophan, the repressor (inactive) binds with tryptophan and gets activated. This active repressor attaches with operator and prevent polymerase to bind and thus inhibiting transcription of genes in the operon.
The mutant strain cannot attach to operator (trpO+) but it can make dimers. As the operator is mutated so it prevent binding of repressor to operator. Thus, expression of the trp operon is repressible.
<span>An Organism. An organism is any living plant, animal, or single-celled creature capable of response to stimulus.</span>
Answer:
DNA replication is the process by which DNA makes a copy of itself during cell division.
Explanation:
DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the basis for biological inheritance.
