What is the difference between structural and functional proteins? And please give a definition for both!

Functional proteins are a complex mixture of biologically active protein which help to support and maintain normal immune functions. Examples of functional proteins are immunoglobulins and avidin.
Structural proteins are fibrous proteins which are part of the structures found in the living cells. Examples of structural proteins are keratin and collagen.
The major difference between these two types of protein is that structural proteins are used as structures while functional proteins perform specific active functions in the cells. Also, structural proteins are usually dominated by two dimensional structure while the functional proteins have three dimensional structures.

You add the following components (in the correct volumes and concentrations) to a tube to perform a PCR reaction Buffer Magnesiu

uranmaximum [27]

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).
