ANEK [815]4 years ago

Answer:

The correct answer is : A.

Explanation:

  • This is because of the following reasons:
  1. Escherichia coli is a bacteria and hence is a prokaryote.
  2. The cloning of human (eukaryote) genes is done to obtain in-vitro protein expression which are to be used a pharmaceutical compounds.
  3. Although the phenomenon of Central Dogma takes place in both Prokaryotes and Eukaryotes, the mechanism is very different.
  4. Some of the differences includes:
  • Eukaryotic genes contain certain non-protein encoding sequences called the Intron sequences which needs to be removed from the transcribed mature mRNA by Spliceosome. This phenomenon is absent in prokaryotes as they do not possess introns. Hence, proper processing of eukaryotic mRNA is not possible in prokaryotes.
  • The mature eukaryotic mRNA has a 5' cap and 3' polyadenylated tail which is added by a capping enzyme and a poly-A polymerase enzyme to increase their stability. This will not be possible in a prokaryote as they lack these enzymes.
  • The translation of membrane proteins and secretory proteins is carried on by the ribosomes bound to the endoplasmic reticulum. This structure is absent in prokaryotes, hence they will be unable to produce a proper polypeptide sequence.
  • Finally, the eukaryotic proteins undergo various modifications after formation, like methylation, acetylation, etc. These reactions cannot be carried out in a prokaryote as they lack the respective enzymes.
  • Hence, we see a properly folded functional eukaryotic protein cannot be produced in a prokaryote.

Answer:

Mark

Explanation:

At divergent plate boundaries, earthquakes tend to be weak and shallow. Transform plate boundaries, have shallow, but very powerful earthquakes. At convergent plate boundaries, where two continental plates collide, earthquakes are deep and also very powerful.

How did the asteroid that smashed into Yucatan, Mexico 66 million years ago kill so many organisms (including the non-avian dino
Bad White [126]

Explanation:

Dinosaurs are living organisms that depends on the environment for survival. As the asteroid hits the Yucatan Peninsula area about 66 million years a couple of things can happen:

Frictional heating of the surface as the earth collided with the asteroid. This heating will cause surface temperature to rise globally and can induce the phenomenon of global warming. This can lead to release of water from reservoirs on the earth surface and hence flooding.

The impact can lead to increase in surface pressure beyond normal and that which life has adjusted to.

Debris in form of dust will be released into the atmosphere and a global air pollution will occur. Gases useful for life will be highly polluted by the vast amount of dusts and other particles discharged into the atmosphere.
