what is the approximate total length of DNA in chromosomes in a single cell
Answer by Chuckgilbert. Confidence votes 4. Chromosomes vary in size, but the DNA would generally be a few cm (inches). The total length of one copy of all chromosomes is about 1 meter (a little over 3 feet).Since you have one copy from each parent, the total is about 2 meters per cell.nswer by Chuckgilbert.
