Scientists can also glimpse the awful effects of Alzheimer's disease when they look at brain tissue beneath the microscope:

Alzheimer's tissue has numerous fewer nerve cells and synapses than a well brain.

Plaques, unusual clusters of protein particle, which are construct up between nerve cells. Dead and dying nerve cells contain tangles, which are produce of twisted strands of a further protein.

Scientists are not absolutely sure what causes cell death and tissue deficiency in the Alzheimer's brain, but plaques and tangles are key suspects.

According to the passage, which of the following topics of study was the most crucial to his final analysis?

TEA [102]

Answer: The study of plant varieties.

Explanation:

This question relates to the studies that Gregor Mendel, founder of modern genetics, performed at the University of Vienna.

Experimenting on pea plants, Gregor Mendel was able to establish a lot of the rules of heredity that we know today even though his research was not fully appreciated or understood during his own life.

He credited the study of plant varieties to have been most crucial to his final analysis because farmers had been crossbreeding varieties for millennia to bring about better traits in plants.

Answer:

<h2>They provide a 3’ end for the DNA polymerase.</h2>

Explanation:

Polymerase chain reaction (PCR) is an in-vitro method to making copies of a specific DNA sample in a very short time.

Polymerase chain reaction was invented by Kary Mullis in 1983.

Primers are specific to the DNA which we want to replicate and they bind to the specific sequence which is complementary to it. Primers provide a 3’ end for the DNA polymerase.
