This statement is FALSE.

Explanation:

spirillum bacteria do not have endoflagella. Instead their flagella are external which is only connected to one end of the cell. While on the other hand spirochetes have endoflagellum which wrap around the cell body. See picture with prominent difference.

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).

People with severe or very severe are in risk of life threathing infections and bleeding.

Leukemia- Is a cancer to blood or bone marrow .Large numbers of white cells are produced in the bone marrow and crowd it and the bloodstream and they cannot perform the proper role of protecting and fitting against diseases.Blood has to go everywhere to bring to body what it needs, making it a stuff cancer.

Major progress and been made targeting this cancer, take the blood out of the body, separate your cancer blood from your good blood, better ways to kill only the bad blood, make more good blood faster, relax your body, mind, improved immune system.
