which of the following statements is correct regarding the affect of pH on the ionization of R groups in amino acids. Put yes or no next to each number. 1) at an acidic pH, amino groups in an R group tend to lonize by accepting a proton and have a positive charge 2) at an acidic pH, carboxyl groups in an R group are likely to be in an unionized state. 3) at an alkaline pH, amino groups in an R group have a tendency to remain unionized (and uncharged). 4) at an alkaline pH, carboxyl groups in an R group have a tendency to lonize by loosing a hydrogen ion (H+) 5) R groups that do not have an amino or carboxyl group do not ionize at pH of the environment changes.
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.

5) R groups that do not have an amino or carboxyl group do not ionize at pH of the environment changes.
Amino acids are the monomeric unit of proteins. Amino acids have same basic structure with varying side chain. There are 20 amino acids, each of them has one amino group, one carboxyl group , one hydrogen and a variable side chain. Side chain provides characteristic properties to the amino acid.
