Explanation:
A peptide bond is a covalent bond formed between the carboxyl group (-COOH) of one amino acid and the amino group (-NH₂) of another, releasing a water molecule (condensation reaction). Glycosidic bonds link monosaccharides, phosphodiester bonds link nucleotides in DNA/RNA, hydrogen bonds stabilize secondary structures. Peptide bonds create the polypeptide backbone.

Explanation:
The central dogma, proposed by Francis Crick, describes the flow of genetic information from DNA to RNA (transcription) and then to protein (translation). Information cannot flow from protein to nucleic acid. However, exceptions exist: reverse transcription (RNA → DNA) in retroviruses, and some regulatory RNA functions. The fundamental principle still holds.
