The human genome has three billion base pairs per haploid set of chromosomes, and 6 billion base pairs are replicated during the S phase of the cell cycle. There are multiple origins of replication on the eukaryotic chromosome; humans can have up to 100,000 origins of replication.

It mentions techniques such as footprinting and chromatin immunoprecipitation for studying DNA-binding proteins and covers specialized topics, including cell-specific gene expression, imprinted genes, and ribozymes.

It notes that in most eukaryotes, the sperm is small and motile, while the egg is larger and serves as nourishment for the developing embryo, fulfilling the different needs for mobility and nutritional support during embryonic development.

It highlights mitochondrial DNA (mtDNA) mutations as a cause of diseases, influenced by heteroplasmy. Mitochondrial Replacement Techniques are being studied to prevent the transmission of defective mtDNA from mothers.

Pyruvic acid then undergoes fermentation in yeasts (producing ethanol and CO2) or lactic acid in red blood cells and muscles. Both fermentation routes are energy-inefficient. In contrast, pyruvic acid is fully oxidized in mitochondria during cellular respiration, capturing approximately 40% of glucose's energy as ATP.
