Answer:I HAVE THE SAME ONE LET ME KNOW WHEN YOU HAVE THE ANSWER!!!
Explanation:
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>Postsynaptic potentials are changes in the membrane potential of postsynaptic terminal. A depolarizing synaptic potential is also known as an excitatory postsynaptic potential. it is the synaptic potential that makes postsynaptic neuron likely to fire an action potential. Postsynaptic neuron is of two forms excitatory and inhibitory.</span>
