What building-block molecules does the body need to prevent anemia?

If water had a low specific heat, we would boil over with the least activity. In other words, if water had a low specific heat, then the bodies of all animals and humans would change quickly as the temperature of the environment changed. This would be deadly. No part of your body could be unprotected from the environment. If it was unprotected, the blood would freeze, expand, and crack open the skin.

Carbonic anhydrase is an enzyme that assists rapid inter-conversion of carbon dioxide and water into carbonic acid, protons and bicarbonate ions. As a result, with any mutation, it wouldn't be able to efficiently transfer CO2 out of our blood, causing our blood to become highly acidic, leading to death.

Nucleotides are the main macromolecules involved in transcription and translation. Another are amino acids, that come together to form protein.

Central Dogma of Biology: DNA RNA    Protein

** DNA is made up of sugar (deoxyribose), phosphate, and four nucleotides.

DNA is the carrier of genetic information in organisms.  What does that mean?   Large molecules in organism can have many functions: they can provide structure,   act as catalyst for chemical reactions,  serve to sense changes in their environment (leading to immune responses to foreign invaders and to neural responses to stimuli such as light, heat, sound, touch, etc) and provide motility.  DNA really does none of these things.  Rather you can view it as an information storage system.   The information must be decode to allow the construction of other large molecules.   The other molecules are usually proteins, another class of large polymers in the body.  Chromosomes are located in the nucleus of a cell.

Thank you very much, I was wrong on answer 5. Thank you!!
