Here's why:
* Genes are instructions: Genes are segments of DNA that contain the instructions for building and maintaining an organism.
* Transcription: The process of copying a gene's DNA sequence into a messenger RNA (mRNA) molecule is called transcription.
* mRNA carries the message: mRNA acts as a messenger, carrying the genetic instructions from the DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis takes place.
* Translation: The mRNA molecule is then translated into a protein, using the genetic code.
So, each gene on a chromosome can be transcribed into its own unique mRNA molecule, which then directs the synthesis of a specific protein. This is how the information stored in our genes is used to create the diverse proteins that make up our bodies and carry out all the functions of life.
