how many molecules of dna are in a human cell
Best Answer: Each nucleus in a diploid human cell has 46 chromosomes . Each chromosome is made of 2 chromatids. Each chromatid is 1 DNA molecule. This gives 92 DNA molecules in the nucleus. Mitochondrial DNA (mtDNA) is present in mitochondria as a circular molecule and in most species codes for 13 or 14 proteins. The number of mitochondria in a cell depends on the cell's function.
