If you stretch out and lay the chromosomes in just one cell end to end, those chromosomes will measure _____?

Question

I'm doing this for a worksheet in biology

Answer 1

Laid end-to-end, all 46 chromosomes in a cell would extend only 0.2 millimeters.  However, if all of the DNA (i.e., genetic material) were laid end-to-end, it would extend over 1.8 meters!
