The different colored bases (adenine, thymine, guanine, and cytosine) represent the genetic code that instructs cells how to make proteins. Understanding this structure is essential for studying ...

Prokaryotic organisms contain one type of rRNA gene that encodes three ... these RNAs all share the same basic single-stranded chemical structure with, in some cases, higher-order structures ...

The next step was to find out its structure, in order to understand how the gene, the basic unit of heredity, works and how it is passed from one generation to the next. Crick and Watson were ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations. The structure so perfectly fit the experimental data that it was almost immediately ...

and it also provides a basic overview of how DNA was discovered. In this unit, you will learn about the basic structure and biological function of DNA molecules, including the biochemical ...

The basic structure of a plant cell is shown below ... Location of reactions in anaerobic respiration. Nucleus Contains DNA which carries the genetic code for making enzymes and other proteins ...
