Which of the following statements below correctly describes how a peptide bond is chemically formed between two amino acids in a 'growing polypeptide chain? O The hydrogen atom on the amino group of the first amino acid is lost while the hydroxyl group on the carboxyl group of the second amino acid is lost to form a peptide bond between the two amino acids. O The hydroxyl group on the carboxyl group of the first amino acid is lost while the hydrogen atom on the amino group of the second amino acid is lost to form a peptide bond between the two amino acids. The oxygen atom of the carboxyl group of the first amino acid is lost while the hydrogen atom on the amino group of the second amino acid is lost to form a peptide bond between the two amino acids. The nitrogen atom on the amino group of the first amino acid is lost while the hydroxyl group on the carboxyl group of the second amino acid is lost to form a peptide bond between the two amino acids.

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.
