What Is It? The genome is like the "Encyclopedia of You." It's the complete set of genetic information in a cell, including both coding (the parts that tell the cell to make stuff) and non-coding sequences (the parts that act like a director, telling the cell how or when to make that stuff).

Real-World Example: Imagine your genome is the complete recipe book of a bakery. It's got every single recipe the bakery could ever make.

What Is It? The transcriptome is the set of all mRNAs (messenger RNAs) in a cell. It's like a 'daily menu' that comes from the complete recipe book (genome). The cell doesn't cook every dish every day; it picks and chooses based on what's needed.

Real-World Example: Your transcriptome is like the daily specials board in that bakery. It's the select recipes that the baker decided to cook today.

What Is It? The proteome is the collection of all proteins made by the cell. Think of it as the final dishes made according to the 'daily menu' (transcriptome). But just because a recipe is on the daily specials board doesn't mean you'll get tons of it—sometimes you might get only a couple of cupcakes or a single loaf of bread.

Real-World Example: The proteome is the actual baked goods you see on display. These are the items that got baked from the 'daily specials' list.
