Human cells do not contain circlular DNA molecules. True or False, Explain your answer

Solution

False.

DNA is the carrier of genetic information. Before a cell divides, DNA must be precisely copied, or \"replicated,\" so that each of the two daughter cells can inherit a complete genome, the full set of genes present in the organism. In eukaryotes , the DNA molecules that make up the genome are packaged with proteins into chromosomes, each of which contains a single linear DNA molecule. Eukaryotic chromosomes are found in a special compartment called the cell nucleus. The genomes of bacterial cells (prokaryotes ), which lack a nucleus, are typically circular DNA molecules that associate with special structures in the cell membrane. Despite the hundreds of millions of years of evolutionary history separating eukaryotes and prokaryotes, the features of the replication process have been highly conserved between them.
