The answer is NO. This is because different environments require different adaptations. A desirable trait in one environment may be inconsequential or detrimental in another environment. This is the reason also why evolution is continuous as natural selection acts on traits of a population to ensure desirable traits are retained with changes in the environment in a dynamic world.

DNA is considered the molecule of life because it contains the instructions that ensure the continuity of life. Employment of DNA to code for protein is the basis of all life on earth.
In all living things, inherited DNA is used to code for amino acids which when joined or linked together in a deliberate specific manner form polypeptides which make up proteins. These proteins are responsible for structure and function of cells.
For example DNA provides information to make four polypeptide (two beta and two alpha ) chains which make up hemoglobin, the protein that functions as the oxygen carrier in red blood cells. In summary,
DNA → protein → trait, and that relationship is the physical basis of life.
Answer:
The pipe cleaners should be made circular to signify that prokaryotes do not have chromosomes
Explanation:
Prokaryotic and eukaryotic cells have a number of distinct features. Prokaryotes lack membrane-bound organelles, whereas eukaryotic cells are compartmentalised with different organelles performing different function.
As a result, prokaryotes no not possess a nucleus, where the DNA is housed in the cell. Eukaryoric DNA is organised into chromosomes. However, prokaryotic DNA is much more simple (and there is usually much less of it), and instead of forming chromosomes, it is organised into a singular, circular molecule, sometimes called the bacterial chromosome.
Therefore, the student will need to take one pipe cleaner and form a circle with it to make the bacterial DNA.
