The correct answer will be option-B.

Explanation:

A neurotransmitter is a chemical messenger used by the nerve cells to transmit the signals from one neuron to another neuron and muscle cell at the synaptic cleft. The common neurotransmitter is acetylcholine, dopamine, serotonin and others.

The neurotransmitter can be excitatory that is causing the generation of the action potential in the neurons or inhibitory that is prevent the generation of neuron in neuron cell. This depends on the receptors to it binds.

The neurotransmitters can be degraded or can be taken back after the work is completed. thus, Option-B is the correct answer.

In this experiment of Gregory John Mendel where he made a cross between a purebred tall plant and a purebred dwarf plant and in the first generation all the offspring were tall.

It can be explained by that every offspring get one allele from both parents and in purebred both alleles are either dominant or recessive and both parent plant gives one allele which makes a heterozygous condition in which the dominant allele masks the recessive allele and offspring express phenotype of the dominant parent.

Which chemical or chemicals inhibit the activity of dnases during dna isolation?
sergij07 [2.7K]

EDTA inhibits the activity of DNase during DNA isolation process.

DNase is an enzyme which degrades DNA using divalent metal ions like Mg^{2+} . These metal ions act as cofactor for the proper functioning of DNase.

EDTA chelates the divalent metal ions and thus does not allow DNase to access them.

Therefore in this way DNA is prevented from degradation during its isolation.
