The answer is A, hope this helps !
Answer:
The mutation is created at a site defined in the DNA sequence. First, it is necessary to synthesize the primer, which contains the mutation. Said primer needs to hybridize with the DNA molecule that has the gene of interest. Using the enzyme DNA polymerase, the mutation is incorporated and allows the formation of the complete DNA. This DNA chain can be introduced into a host cell and subsequently cloned
Explanation:
With this technique it is possible to establish specific mutations, deletions or insertions. Through this it is possible to control the type of mutation that is wanted in the DNA. For example, in the case of deletions, primers are used which, in addition to having their capacity to perform the deletion, should also be able to hybridize the DNA chain. To carry out an insertion, said primer must have the DNA fragment in addition to being able to hybridize the DNA.
Answer: Tau
Explanation:
NFTs or neurofibrillary tangles are insoluble twisted fibers. The tangles are abnormal accumulation that collect inside neurons. Their presence is also found in other diseases such as tauopathies. Statins have been shown to reduce neurofibrillary tangles in mouse models. Lithium has been shown to decrease the phosphorylation of tau. The tau protein is primary maker Alzheimer's disease.
