A labeled schematic shows the two basic components of a single nucleotide molecule. An elongated, red, vertical rectangle is labeled as the nitrogenous base. A gray rectangle, about half as long but twice as wide, is attached to the bottom of the red rectangle and represents a sugar molecule. The bottom-left corner of the sugar molecule is labeled the 3-prime side, and the bottom right corner of the sugar molecule is labeled the 5-prime side, or phosphate side.

DNA Is a Structure That Encodes Biological Information

A schematic shows 24 nucleotides arranged to form a double-stranded segment of DNA using grey horizontal cylinders as sugar molecules and colored vertical rectangles as nitrogenous bases.

DNA Is a Structure That Encodes Biological Information

A labeled schematic diagram shows the structure of the primary cilium. The organelle is depicted as a vertical, cylinder-shaped, cellular protrusion. A ciliary membrane forms the outline of the cylinder; inside the membrane, nine vertical rectangles are arranged in a hollow, ring-shaped configuration. The rectangles represent microtubules, and the ring-shaped arrangement is called an axoneme. Green spheres attached to beige rectangles represent molecules attached to intraflagellar transport…

This food is assisted by the bile and digestive enzymes from the juices in your pancreas, liver, and gall bladder.  These microbes secrete lactic acid, hydrogen peroxide, and acetic acid.  These secretions make good more digestible and also make a very inhospitable environment for the bad microbes ... cont
