Write questions to this answers:
Many biochemists consider proteins the most important substances for study.
Proteins perform many functions within the body.
Carbohydrates.
They are used for longer-term storage of energy within the body.
They include fats, oils, waxes, certain vitamins, some hormones, components of some cell membranes, steroids, fatty acids, and other related biomolecules.
In 1979.
The encoded information is contained and conveyed via the nucleic acid sequence.
Because they function to create and encode and then store information in the nucleus of every living cell of every life-form organism on Earth.
