Answer:
A. To cause intact DNA to precipitate, so the activity of DNase can be determined.
Explanation:
The presence of DNase is special feature for some species of bacteria and can be used for identifying them. During DNase test, diluted hydrochloric acid (HCl) can be poured onto the agar plates so that there will be a clear zone close to the bacteria colonies. Each nucleotides are soluble in diluted HCl. But DNA is not soluble in the diluted HCl, thereby making the DNA to precipitate in the rest of the plate.
Answer:
Gray matter consists primarily of neuronal cell bodies, or soma. This a spherical structure that houses the neuron's nucleus.
<span>Endotherms</span> <span>require</span> <span>a higher
metabolic rate</span> <span>than</span> <span>ectotherms</span>. This is because <span>endotherms</span> maintain a <span>regular/</span> constant body temperature while <span>ectotherms</span> depend on the heat in the <span>environment</span> to regulate body <span>temperature</span>.
Therefore, <span>endotherms</span> must eat regularly to
maintain this metabolic rate and <span>sustain</span> <span>constant</span> temperatures.
The newly identified molecule was RNA.
The cytoplasm synthesize protein through the ribosomes.
The molecule that transports information from the nucleus to the cytoplasm is the tRNA or the transfer RNA.
Thymine is a DNA base which is one of the building blocks in making protein.
