Nitpick: Except during mitosis, which is the only time the chromosomes are visible as discrete structures. At that point, the chromosomes have already been duplicated, so each consists of two DNA strands attached at the centromere. yoyokng1 • 9 yr. ago

WebThe two strands of DNA are antiparallel which means that one strand runs in a 5’ to 3’ direction and the other runs in a 3’ to 5’ direction. WebEach chromosome is formed of DNA and proteins ( basically histamin) . DNA is a double helix; 2 strands, each one has coding areas ( which are 2% and maybe less) and non-coding areas . Within the gene itself there are non-coding sequences which their name is “ introns “.

WebHow many DNA molecules are present in a cell of the human body? Human cells contain 23 pairs of chromosomes (46 chromosomes in total). Each chromosome is formed by 2 strands of DNA that hydrogen-bonded to each other make the classic DNA double helix (double-stranded DNA). So, in total there are 46*2=92strands of DNA in each diploid human cell!
