B.Sometimes true,As you sometimes to need to learn on the alternative provided in getting a solution that is factual
Answer:
The correct answer is "negative".
Explanation:
At pH 2 the net charge of the R groups of all the amino acids that comprise the peptide in question would be positive. This happens because of the high content of protons in a solution of pH 2, a value that is below the isoelectric point of all the amino acids. Since the peptide would have a positive net charge, it would migrate to the negative terminal of the gel because opposite charges attract each other.
DNA, short for deoxyribonucleic acid, is present in the nucleus of eukaryotic cells and floats around in the cytoplasm of prokaryotic cells. DNA produces blueprints which RNA carry out to ribosomes to code for protein. You can say that DNA passes genetic material through generations.
