-**Chromosome 20** is one of the 23 pairs of chromosomes forming the [Human Genome](/wiki/Human_Genome), a silent bearer of life's intricate blueprints. Within its structure lie countless [Gene](/wiki/Gene) sequences, dictating an array of traits and contributing to the complex tapestry of our biology. It is known to carry genes important for development, cellular regulation, and various physiological functions.
-- **PRNP (Prion protein)**: This gene provides instructions for making the prion protein, which is found throughout the body but is most abundant in the brain. Mutations in the *PRNP* gene are associated with various neurodegenerative conditions, including Creutzfeldt-Jakob disease and Gerstmann-Sträussler-Scheinker syndrome, which involve abnormal protein folding.
-- **ADNP (Activity-dependent neuroprotective protein)**: This gene is crucial for brain development and function. It encodes a protein involved in the formation of [Microtubule](/wiki/Microtubule)s, which are essential components of nerve cells. Variations in *ADNP* are linked to intellectual disability and autism spectrum disorders.
-- **TOP1 (DNA topoisomerase I)**: This gene codes for an enzyme that helps in the process of DNA replication and repair by relaxing supercoiled DNA. Its function is vital for maintaining genomic stability.
+**Chromosome 20** is one of the 23 pairs of chromosomes forming the [Human Genome](/wiki/Human_Genome). It is typically metacentric and comprises about 63 million [DNA](/wiki/DNA) base pairs, representing 2-2.5% of the total DNA in human cells. Within its structure lie countless [Gene](/wiki/Gene) sequences, dictating an array of traits and contributing to the complex tapestry of our biology. It is known to carry genes important for development, cellular regulation, and various physiological functions, with an estimated 600 to 700 protein-coding genes.
+- **PRNP (Prion protein)**: This gene provides instructions for making the prion protein, which is found throughout the body but is most abundant in the brain. Mutations in the *PRNP* gene are associated with various neurodegenerative conditions, including Creutzfeldt-Jakob disease and Gerstmann-Sträussler-Scheinker syndrome, which involve abnormal protein folding and aggregation.
+- **ADNP (Activity-dependent neuroprotective protein)**: This gene is crucial for brain development and function. It encodes a protein involved in the formation of [Microtubule](/wiki/Microtubule)s, which are essential components of nerve cells. Variations in *ADNP* are linked to intellectual disability and autism spectrum disorders, highlighting its critical role in neurological processes.
+- **TOP1 (DNA topoisomerase I)**: This gene codes for an enzyme that helps in the process of DNA replication and repair by relaxing supercoiled DNA. Its function is vital for maintaining genomic stability and preventing DNA damage.
