Answer:
Extraction of genomic DNA
Explanation:
Resuspend the cells(any number), smaller numbers also work, in 10-20 ul of TE buffer or milli Q water. boil for 5-10 min in a waterbath, quick chill, short spin. use the supernatant as a template for PCR.
If cells are very less, u can directly add cells to the PCR reaction without enzyme,boil for 5-10 min in a waterbath, let it cool slowly, short spin. Add enzyme to the supernatant and start the reaction at extension step followed by normal PCR reaction steps.
Answer: The primary motor cortex for control of voluntary muscles is found in the precentral gyrus of the frontal lobes.
Explanations:
The primary motor cortex is one of the important brain areas involved in motor function. It is found in the precentral gyrus of frontal lobes. It control voluntary muscles and generate impulses needed for movement execution.
Voluntary muscles are muscles that we can control consciously or we can control them at will and we can choose when we want to use them. They are also refers to as skeletal muscles and are attached to bones. The are majorly use for locomotion.
