Question

A person cannot see a single cotton thread 100 feet away , but if you wound thousands of threads together into a rope it would be visible much further away is this statement analogous to dna extraction? explain

Answer 1

Yes because the single cotton is similar to a single DNA but later when you add something it becomes visible. 
lol this is the exact same question I had for lab

Answer 2

A single strand of the thread and DNA will be very minute and small that cannot be seen from far away. It has a very small size of nanometers that cannot be seen from distance.

No, it is not analogous to the cotton thread.

How is DNA and cotton thread different?

DNA is the genetic material of almost the majority of the cells and is found intact inside the nucleus and is coiled around in helical shapes.

A thread of cotton is very thin and cannot be seen from a far distance but when the cotton threads are intertwined together then they can be seen from distance.

DNA is relatively much thinner and smaller than the cotton thread and even if they are threaded together they will be up to the size of a single cotton thread.

Therefore, cotton thread and DNA are not analogous.
