Answer:
b. False
Explanation:
These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.
The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.
For a PCR reaction to be performed a solution with some components must be prepared. These components are:
- Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
- Forward and reverse primers (to customize the start of the enzyme reaction)
- DNA polymerase (Enzyme required for replication of desired DNA region.)
- DNA Template (the DNA to be copied)
- PCR-grade water
- Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).
The answer is radioisotopes as this has the ability of
breaking molecules apart and aside that, it has the ability of destroying cells
and as well as having to damage living tissues in the body because these are
isotopes that are unstable.
Answer:
Air Pressure
Explanation:
Air pressure is the only option here related to weight. And Air Pressure does get lower the higher the airplane goes.
Nerves that detect deep pressure are called Pacinian corpuscles.
Pacinian corpuscles are microscopic onion-shaped nerve structures that are situated in the dermis and hypodermis. Pacinian corpuscles detect deep pressure and vibration. This nerve has a myelinated nerve ending in the middle of its structure and the external layer contains flattened cells, a lymph-like fluid and collagen fibers. The structure of pacinian corpuscles provides a fast response and rapid recovery by transmitting fast events. This make them sensitive to pressure and vibration.
Answer:
A point mutation is a type of mutation in DNA or RNA, the cell’s genetic material.
Explanation:
DNA and RNA are made up of many nucleotides. There are five different molecules that can make up nitrogenous bases on nucleotides: cytosine, guanine, adenine, thymine (in DNA) and uracil (in RNA), abbreviated C, G, A, T, and U.
