Molecular Genetics and Gene Expression

## From DNA to Protein: Decoding the Genetic Blueprint DNA holds the instructions for building proteins, but how does this information get used? ### Transcription The process begins in the nucleus, where DNA is transcribed into messenger RNA (mRNA). ### Translation The mRNA travels to ribosomes, where it is translated into a protein by matching codons with amino acids. ### Regulation of Gene Expression Not all genes are active at all times. Cells control which genes are turned on or off depending on their needs, which is crucial for development, adaptation, and health. ### Modern Relevance Techniques like CRISPR use this knowledge to edit genes, opening doors for treating genetic diseases.
