Hello. This question is incomplete. The full question is:
"You determine that you have only 3 copies left of an important DNA fragment, so you decide to amplify it. Using flanking primers, how many PCR cycles would you have to run to generate over one billion (10^9) copies of the fragment?
"
Answer:
Approximately 29 cycles of PCR would be required.
Explanation:
As you may already know, PCR is a technique used in molecular biology that allows part of a DNA molecule to be recycled into millions of copies.
PCR allows this replication to be done through cycles. Each PCR cycle lasts about 2 minutes and allows the DNA molecule to undergo the separation of the strands, the binding of the primers and the synthesis of new DNA strands through DNA polymerase. This cycle is usually repeated 32 times, but this number may change depending on the number of copies the researcher thinks is necessary.
In this case, if a researcher wants 10 ^ 9 copies of DNA, he must do the following calculation to find the number of PCR cycles needed:
32 ^ x = 10 ^ 9
x = 28.3 = approximately 29 cycles.
C
in the first paragraph a fact is challenged
and the second one provides an example
Answer: D. regulate the thalamus
Explanation:
The most important functions of the hypothalamus is to link the nervous system to the endocrine system by way of the pituitary gland. It's located at the base of the brain, near the pituitary gland. The hypothalamus is located below the thalamus and it's very small . The hypothalamus plays a crucial role in many important functions and is responsible for the regulation of certain functions including: releasing hormones and regulating body temperature.Regulating the thalamus is not a function of the hypothalamus.
