NettetAnswer (1 of 13): One chromosome has 2 strands of DNA in a double helix. But the 2 DNA strands in chromosomes are very, very long. One strand of DNA can be very short - much shorter than even a small chromosome. Strands of DNA are made by joining together the 4 DNA bases in strings.Mar 14, 2012 ... NettetHow many DNA strands do humans have? The diploid human genome is thus composed of 46 DNA molecules of 24 distinct types. Because human chromosomes exist in pairs that are almost identical, only 3 billion nucleotide pairs (the haploid genome) need to be sequenced to gain complete information concerning a representative human genome.
