All cells don't have in common is an ability to colonize any environment on earth.

Cells- A cell's cytoplasm and nucleus are enclosed in a membrane, making it the smallest structural and functional component of an organism.

Environment- The natural habitat or natural world includes all living and non-living things that arise spontaneously, or in this case, without the use of artificial methods.

Living Object- A living thing is any creature or life form that demonstrates or possesses the characteristics of life or being alive.

Non-living things are inanimate items or forces that have the power to affect, shape, modify, and have an impact on the life of a living creature.

quizlet chromosomes are composed of: please choose the correct answer from the following choices, and then select the submit ans

Anna11 [10]

Chromosomes are composed of deoxyribonucleic acid (DNA) mole

There are mainly two molecules that function as genetic material in living organisms.

These are ribonucleic acid(RNA) and deoxyribonucleic acid(DNA).

The organisms having DNA as genetic material require packaging of DNA as it is a long polymer of deoxyribonucleotides.

In the case of human beings, the length of DNA in a cell is approximately 2.2 meters which is very large as compared to the size of the nucleus( approximately 10^-6 meters).

So, the DNA has to be made compact for it to be present inside the nucleus of a cell.

Therefore, the DNA present inside the nucleus of a cell undergoes coiling and compaction through several stages before finally becoming a chromosome, which is shown in the adjoining diagram.

Thus, chromosomes are composed of deoxyribonucleic acid (DNA) molecules.
