Understanding the Building Blocks: DNA, Gene, and Genome
DNA: DNA is an Instructional Manual consisting informations for our bodies.
Gene : Gene is like a specific chapter in the DNA instruction manual. Genes are specific segments of DNA that influence certain aspects of growth and health.
Genome : Genome is like the entire DNA instruction manual for an organism. Human genome consists of between 20k abd 25k genes.
In most of our body’s cells, you can find DNA, which is full of instructions to make proteins and these proteins are crucial for cells and our body to function well. Genes are like smaller sections in the manual that tells our cells how to make these proteins.
Here’s the trick: Not all the instructions in the manual/DNA are needed all the time. For example, a liver cell only uses the parts of the manual (gene) that help it grow and do liver stuff, and heart cell uses different parts for its job and the rest of the genes are repressed or turned off.
