The correct answer is option D. Mars is a long distance away.
According to the universal law of gravitation, the effect of the force of gravity decreases as the distance increases. The gravitation force is inversely proportional to the radius or the distance. So, the gravitational force exhibited by the Mars is not experienced by us due to the large distance.
Answer:
Nuclear Localization Signal (NLS).
1. Importin
2. Nucleoporin
3. RanGTP
Explanation: The specific amino acid sequence motif that allows the selective transport of proteins having a molecular mass more than approximately 40 KDa into the nucleus is called Nuclear Localization Signal (NLS).
These proteins enter the nucleus through the Nuclear Pore Complex (NPC). The transit of the protein from the cytoplasm to the nucleus requires binding to a <u>receptor</u> called Karyopherin or Importin β, this receptor binds to the protein by <em>direct recognition of the NLS</em> sequence or through <em>an adapter </em>protein, Importin α (depending on the NLS sequence).
The passage of the complex through the NPC needs, in turn, the <em>binding of the </em><em>Importin </em><em>to the </em><em>Nucleoporins</em>, <u>proteins that form the nuclear pore</u>.
Once the complex passes through the pore, the <em>receptor-bound protein is released</em> <em>by the interaction</em> of Importin with RanGTP, an enzyme with guanosine triphosphate (GTP) hydrolytic activity.
Answer:
a.moving herbicide resistance to weeds
Explanation:
Herbicides are chemicals that are used to kill unwanted plants that can affect the growth of crops. Herbicide resistant plants are those that do not die following exposure to a herbicide.
Moving herbicide resistance to weeds would mean that weeds do not die following herbicide treatment, which is not a desired effect of biotechnology. Therefore, a is correct.
