1. DNA to mRNA: DNA, found within chromosomes, contains the genetic code. This code is transcribed into mRNA, a single-stranded molecule that carries the genetic information from the DNA to the ribosomes.
2. mRNA to Ribosomes: mRNA travels from the nucleus, where the DNA is located, to the cytoplasm where ribosomes are found.
3. Protein Synthesis: At the ribosome, mRNA is translated. This means the genetic code is read, and the ribosome assembles amino acids into a specific protein based on the instructions carried by the mRNA.
So, while chromosomes contain the genes, the actual message they send to ribosomes is carried by mRNA, which acts like a messenger to tell the ribosome what protein to build.
