In humans, the average length of a gene on chromosome 7 is 69,000 base pairs, but the average mRNA length on chromosome 7 is only 2,500 base pairs. Chromosome 7 has 863 protein-coding genes, but many more than 863 proteins are made from the genes on chromosome 7. The observation that the length of the average gene on chromosome 7 is longer than the average MRNA length is explained by the process of, while the observation that more proteins are produced from the genes on chromosome 7 than there are genes can be explained by the process of heterogeneity; complementation splicing of introns; alternative splicing chromatin remodeling; micro RNA binding acetylation; methylation O alternative splicing; splicing of introns

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
