Final answer:
The human genome includes 46 chromosomes in the nucleus of somatic cells and mitochondrial DNA, making the statement true.
Step-by-step explanation:
The statement that in humans, the genome consists of the 46 molecules that form the chromosomes inside the nucleus, plus the DNA found within the mitochondria is true. Human body cells have 46 chromosomes, arranged in 23 pairs, and this diploid configuration contains two matched sets of chromosomes. In addition to nuclear DNA, humans have mitochondrial DNA, which is inherited exclusively from the mother and is a separate genetic contribution outside the nucleus.
The human genome contains over 20,000 genes, with DNA that is precisely wound, folded, and compacted into chromosomes to fit inside the nucleus. Apart from the 46 chromosomes in somatic cells, there is also a mitochondrial genome, which is comprised of a small circular DNA molecule.
