Protein transport into the endoplasmic reticulum (ER) or mitochondria requires unfolding of the protein and threading the amino
NemiM [27]

Answer:

The nuclear pore complex is a huge structure composed of about 30 different pore proteins, and its central channel has a diameter of approximately 10-40 nm, which is large enough for even very large protein complexes. For this reason, it is unnecessary to unfold the protein, which can pass through the pore in its native state.

Explanation:

  • Protein transport into the endoplasmic reticulum (ER) or mitochondria requires unfolding of the protein and threading the amino acid chain through a channel or pore into the organelle.
  • In contrast, protein transport into the nucleus does not require unfolding of the protein.
  • This is because, nuclear pore complex is a huge structure composed of about 30 different pore proteins, and its central channel has a diameter of approximately 10-40 nm, which is large enough for even very large protein complexes. For this reason, it is unnecessary to unfold the protein, which can pass through the pore in its native state.

During the course of an E. coli transformation laboratory, a student forgot to mark the culture tube that received the kanamycin
Gwar [14]

Answer:

The plate that contains Kanamycin in it will have growth of colonies of bacteria that have been transformed with the plasmid which has the kanamycin-resistant gene. The bacterial cells that did not get transformed with this plasmid will not be able to grow into colonies in the presence of kanamycin.

While the negative control, a plate with any other antibiotic,such as ampicillin or tetracyclin, added to it will not allow growth of any bacteria on it.

Hope that answers the question, have a great day!

“Why is it important to protect biodiversity?”<br><br>(i need a paragraph size answer)
Aloiza [94]
It is important to protect biodiversity because it is the key to a sustainable and productive ecosystem. Biodiversity enables most, if not all, of the niches of an ecosystem to be filled. It also serves to protect the food web within the ecosystem, for the higher the biodiversity the lower the effects of removing or changing a species.

A student from one of the research labs is having trouble preparing a slide for examination and photographing. The bacterial sli
ankoles [38]

Answer: Rinsing with alcohol during the washing step stripped the bacteria off the glass slide.

Explanation:

The step that is being wrong in the whole experiment is that the student is washing the bacteria on the slide with alcohol.

Alcohol might have washed off all the bacteria as it is corrosive in nature. The bacteria that is going to be observed in the experiment is being killed when it is washed off.

This was the wrong step opted by the student if he finds any alternative solution to this then the bacteria can be observed in the microscope.
