Answer: B. Melting temperatures of primer should be between 55-80 degree Celsius.
Explanation:
Bacause the melting temperature controls the binding of the primers to your template DNA. At melting temperature 50% of the primer molecules are bound to their corresponding target sequence. If the difference in melting temperature between the two primers is too high, it might be difficult to find experimental conditions where both primers can bind to their target.
Answer:
Stem cells are special human cells that have the ability to develop into many different cell types, from muscle cells to brain cells. In some cases, they also have the ability to repair damaged tissues.

<h3><u>What is the role of decomposers in ecosystem?</u></h3>
Saprophytes like fungus and bacteria are decomposers. They rely entirely on the dead and decomposing organic debris to survive. Decomposers are crucial to the ecology because they assist in recycling nutrients so that plants may utilise them again.
The function of a decomposer in the ecosystem is as follows:
- By disintegrating dead plants and animals, they first serve as a purifying force for the environment.
- They aid in the nutrient recycling.
- By allowing the dead to decay, they provide room in the biosphere for new life.
- For the benefit of reuse by producers like crop plants, they assist in reintroducing the various elements to water, soil, and air.
