Here's a breakdown:
* Genes: Segments of DNA that contain the instructions for building and maintaining an organism.
* Proteins: Complex molecules that perform a wide variety of functions in the cell, including:
* Structural support: Providing framework for cells and tissues.
* Enzymes: Catalyzing biochemical reactions.
* Hormones: Acting as chemical messengers.
* Antibodies: Defending against infection.
* Transport: Moving molecules across cell membranes.
The process of converting genetic information from DNA into proteins is called protein synthesis. It involves two main steps:
1. Transcription: The DNA sequence of a gene is copied into a messenger RNA (mRNA) molecule.
2. Translation: The mRNA molecule is used as a template to assemble a chain of amino acids, which fold into a functional protein.
So, in essence, genes are the blueprints for making proteins, which are the workhorses of the cell.
