Answer:
Hydrogen Bonds
Explanation:
In the polymerase chain reaction (PCR) the temperature rises to 90 ° C - 95 ° C, to break the hydrogen bonds, which are the types of bonds responsible for pairing the two strands of DNA, this process is known as denaturation of DNA.
The DNA is extremely stable, due to a large number of bonds (hydrogen bonds) that form between the two strands. If the temperature decreases, these bonds will begin to recompose, until the DNA returns to its original state
Answer:
The correct answer is B. DNA helicase first unwinds the double helix around the +1 site.
Explanation:
The helicase is an enzyme that specifically breaks the hydrogen bonds of the bases in the transcription process. As E. Coli is a prokaryote, then, the transcription only occurs in one point of the circular DNA. The promoter region indicates where the DNA polymerase has to start replicating and the Topoisomerase unwinds the parts of the DNA that are being excessively twisted because of the separation of the two strands.
Answer:
The correct answer is - true.
Explanation:
The scientific journal is are the journals that publish the recent scientific findings or scientific experiments that produce new and appropriate results regarding particular experiment or research/
To confirm an experiment, published finding must be tested repeatedly by different scientists and researchers and see if the results are same in particular conditions.
Thus, the correct answer is - true.
Answer:
B, G , E, F.
Explanation:
Hemoglobin is known to be a tetrameric hemeprotein, which is found in the erythrocytes where it binds with oxygen,and then the bound oxygen is transported to parts of the body.
Myoglobin is a monomeric protein that is found in the muscle tissue. Its function is that, it serves as intracellular storage site for oxygen.
It should be understood that, both hemoglobin and myoglobin are hemeproteins with physiological importance of having the ability of binding molecular oxygen.
In this case, it is also known that, the two, that is hemoglobin and myoglobin have a prosthetic group called heme, which is described or known to be a tightly bond, specifically a non-polypeptide unit which is required for biological function of some protein.
