If Cas9 edits DNA, why is a molecule of RNA needed in a CRISPR complex?

Biology
1 answer:
pantera1 [17]3 years ago
6 0

Explanation:

The use of CRISPR/Cas9 avoids the need for protein engineering to develop a site-specific nuclease against a specific DNA target sequence, requiring only the synthesis of a new piece of RNA. This dramatically simplifies and greatly reduces the time needed for gene editing design and implementation.

Acid rain and other forms of pollution can cause soil acidification, which decreases the number of decomposers in the soil. What
Liono4ka [1.6K]

Answer:The question is incomplete because the options are not given. Here are the options.

a. The level of energy available in the ecosystem would increase, which would cause the population of autotrophs to increase.

b. The level of available nutrients in the soil would decrease, which would cause the population of producers to decrease

C. The population of primary consumers would increase because of increased production by autotrophs.

d. The population of primary consumers would increase because of decreased competition from decomposers.

The current answer is option B.

The level of available nutrients in the soil would decrease, which would cause the population of producers to decrease.

Explanation:

This is because when the soil is acidic it will reduce the availability of plants nutrients in the soil and it will result in accumulation of toxic chemicals which can affect the growth of plants.

If nutrients are not available for plants growth which is primary producer, it will result in poor growth, low photosynthesis and hence the production of glucose will be reduced because nutrients is essential for plants growth.
