Structure of DNA and RNA

Understandings:

The nucleic acids DNA and RNA are polymers of nucleotides.

• Nucleotides are the monomers of the polymer DNA.
• DNA nucleotides are made up of 3 components: a phosphate group (PO₄^-3), a pentose sugar, and a nitrogenous base.
• The phosphate, sugar, and base are linked by covalent bonds.
• In DNA and RNA, each nucleotide is linked to the next nucleotide between the phosphate of one and the pentose sugar of the other nucleotide.

DNA differs from RNA in the number of strands present, the base composition, and the type of pentose.

The digestive system is responsible for the ingestion, digestion, absorption, and elimination of food. It transforms food into nutrients through three main processes:

1. Mechanical Digestion: Chewing, grinding, crushing, and mixing of food to break it down into smaller pieces.
2. Chemical Digestion: Digestive juices break down macromolecules in food into smaller molecules that can be absorbed.
3. Absorption: Nutrients are absorbed into the bloodstream and transported to cells throughout the body.
