The difference is 1) sugars dissolve in water lipids don't. 2) sugars are made-up of subunits that form large polymers and lipids are not and don't form polymers. 3)Lipids store more energy than sugars hoped i helped
answer: The atoms of different elements all have different numbers of protons. Meanwhile, the mass number of an atom consists of the total number of protons and neutrons it contains
Explanation:
It is obvious that the sandstone is older than the granite. This is because the sandstone had to already exist when the granite formed from molten rock, as some of the sandstone was captured within the layer of hardening granite. The geological principle of inclusions supports this conclusion.<span> Inclusions, in this case the sandstone, are always older than the rock they are found in. </span>
Answer:
No, it is not
Explanation:
Heterozygous is Gg, and if the dominant gene is there, it masks the recessive one.
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.
