Answer:

RNA is mostly single-stranded; DNA is always double-stranded.

Explanation:

DNA stores the genetic information that codes for the way protein should be developed by the cell. Protein determines the trait (phenotype) of the cell/organism. RNA is used as an intermediary between DNA and proteins.  RNA is made of ribonucleic acids  while DNA is made of deoxyribonucleic acids.

Like all enzymes, restriction endonucleases (REs) need to be handled very carefully to ensure that they do not denature. Which o

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.

atroni [7]
Your answer is B Plant cells have cell walls instead of cell membranes because plants have cell walls to support, protect, and carry water through out the cell animals cells don't have that. Its also not A because they both have vacuoles its not C because they both have choralpast.

Your answer is B.

BTW if not B its all of the above.
