Which statement correctly describes the organization of dna and its related structures?

dna is contained in the cell nucleus, and the cell nucleus is contained in chromosomes.

dna is contained in chromosomes, and chromosomes are contained in the cell nucleus.

chromosomes are contained in dna, and dna is contained in the cell nucleus.

chromosomes are contained in the cell nucleus, and the cell nucleus is contained in dna.

The correct option will be DNA is contained in chromosomes, and chromosomes are contained in the cell nucleus.

Explanation:

DNA is the genetic material of the eukaryotic organisms which is organised into highly specialized structures to fit in the nucleus of every cell.

DNA forms association with proteins to form compact structure as:

1. 11 nm nucleosomes- formed by wrapping of DNA around histone proteins   forming nucleosomes which appears as beads on a string structure.

2. 30 nm fiber- formed by folding of nucleosomes which form compact structure.

3. 300 nm looped structure- solenoid structure formed by folding of 30 nm fiber.

4. 700 nm chromosome structure- formed by folding of 300 nm structure forming compact structure called chromosome.

So, the continuous thread-like molecule of DNA forms a compact structure called chromosome by forming association with proteins which fits into the microscopic space of the eukaryotic nucleus.

Thus, DNA is contained in chromosomes, and chromosomes are contained in the cell nucleus is the correct answer.

earthquakes in florida are rare because the state is not located near any tectonic plates. in fact, florida is tied for first place as having the fewest earthquakes of any state. much of florida is limestone and seafloor materials that is not conducive to earthquakes.

explanation:

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
