Yes, quite frankly it is possible to find a same gene if you're in the same class of species, but finding the protein....I believe that's impossible because in every type of gene, you have the same proteins that make you function the same way. Without them you wouldn't be able to function properly.
If I found the same gene in all organisms that I've tested, I would be intrigued because that would be a giant step in evolution. My reason for this answer is because if you have the same gene that would technically mean we all specifically came from the same species of animals.
No, that's not true because other characteristics would eventually help us in many things, studies would help us get our brain much stronger and the intelligence level would be extraordinary.
Answer:
The correct answer is: d. REs activity is best preserved by freezing the RE and thawing it out for brief periods of time as needed.
Explanation:
- Restriction enzymes can be defined as endonucleases that can recognize specific nucleotide sequence in a DNA (Deoxyribonucleic acid) sequence and cause breakage of phosphodiester bond in the DNA at the target site. Hence, it has the capacity of cleaving a DNA sequence.
- These are made up of proteins which are required to be present in the accurately folded conformation in order to function.
- Any form of alteration in the three-dimensional structure of the protein induced due to physical, chemical, mechanical or physiological factors can cause denaturation of the protein which in turn can render the protein non-functional.
- Freezing of restriction enzymes (REs) directly without the use of glycerol will cause the movement of water molecules within the proteins as well layering of water molecules on the protein surface.
- At low temperature these water molecules change to ice crystals which can alter the conformation of the protein or can cause breakage of peptide bonds in the proteins by physical force.
- This can cause the protein to get denatured and hence non-functional.
- Hence, it is never advisable to preserve REs by freezing directly without glycerol.
- Glycerol forms a layer around the protein molecules and prevents the protein molecules from coming into direct contact with the water molecules and hence prevents protein denaturation.

To inhibit cell division, such as those meant to treat cancer.
Answer:
The correct answer is- law of independent assortment
Explanation:
Law of independent assortment says that assortment of one gene pair is independent of assortment of other gene pair which means each contrasting gene pair bears no association with other pairs of contrasting character and behave and segregate independently.
This allows the combination of new characters in the offspring. So it helps in increasing the genetic variability in the gene pool. Therefore law of independent assortment tells that inheritance of one trait had no effect on the inheritance of another.
