Answer:
The central dogma of molecular biology best describes the relationship between proteins and nucleic acid.
Explanation:
Nucleic acid such as DNA is the repository of genetic information in most organism.
The genetic information stored in DNA is Transferred to RNA by transcription which deals with the the production of mRNA from DNA.
The mRNA then undergo translation to transfer its own own genetic information in form of codons to specify amino acids of a protein molecule.
Thus the Central dogma of molecular biology relates proteins and nucleic acids.
Answer:External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.
