What can CRISPR/Cas9 target?

1 answer:

3 0

The CRISPR-Cas system is widely found in bacterial and archaeal genomes as a defense mechanism against invading viruses and plasmids [1–6]. The type II CRISPR-Cas system from Streptococcus pyogenes relies on only one protein, the nuclease Cas9, and two noncoding RNAs, crRNA and tracrRNA, to target DNA [7]

Nitrogen-fixing bacteria carry out the conversion of gaseous nitrogen to a biologically useful form of nitrogen
An energy pyramid illustrates that energy in the form of heat is lost to the surroundings as it is passed from one organism to the next
The energy role of a grizzly bear is that of a consumer because it cannot make its own food
Decomposers cycle nutrients from dead organisms back to the soil, where it becomes available for plants
The Savanna biome is characterized by its lack of trees, warm temperatures, and moderate rainfall

Explanation:

The nitrogen-fixing bacteria like Azotobacter which lives in symbiotic relationship in the rhizomes of leguminous plants. They convert inorganic atmospheric nitrogen gas through the action of its enzymes like nitrogenase to organic nitrogen in the form of ammonia, which is readily assimilated by the plants.
In an ecosystem, at each tropic level of an energy pyramid, only 10% of energy is utilized and transferred to the next higher tropic level whereas the majority of energy is dissipated as heat during various metabolic processes.
Decomposers also called saprophytes like earthworms, bacteria, fungi survives on dead and decayed remains of plants and animals and also on fertilizers, pesticides etc in the soil. They recycle the nutrients by breaking down the complex biomolecules into simpler forms and release back into the soil.
Grizzly bears being omnivores eat both plants and animals according to their availability. Hence they are both primary and secondary consumers.
Savanna is a grassland biome with a typical tropical wet and dry climate and receives moderate rainfall. Hence it cannot support trees but only have grasses.

Cells in a hypertonic solution tend to:

marshall27 [118]

Answer:

Shrink due to water loss

Explanation:

A hypertonic solution has more osmolarity than the cell. This causes the water inside the cell to go out since the osmolarities tend to equalize. And the cell does not allow the passage of other substances except water. Therefore the water will come out and the cell will shrink.

In a hypotonic solution, the water will enter into the cell and in an isotonic solution the water will be moving into and out of the cell at the same rate.

What responsibilities do humans have on the environment

kykrilka [37]

Answer: Environmental responsibility. ... Respect the environment, making rational use of natural resources and taking steps to prevent pollution from the different processes involved in our industrial operations. Promote the sustainable use of raw materials and natural resources. In fact, our cognitive ability and understanding of nature obliges us to maintain the integrity of the environment. So we must change how we influence the land. We must respect the natural order of things and find a way to live accordingly.

Accordingly u can take points from this and then add to ur ans. I hope i was helpful

Answer:

The genes will be Rr or rr.

Explanation:

Becuase the first generation didn't have the trait, which means the second generation's grandparents had the trait. That's why, the second generation female is mixed, which means the male child can be rr or Rr.
