stellarik [79]3 years ago
4 0

The herpes virus infects the humans to cause chickenpox disease. The virus during its stage of causing infection, it spreads through the epidermal cells by infecting them. This causes the typical rash on skin that is seen in chickenpox. The virus then enters that sensory nerves present on the ski and travels along the length of the neurons to the sensory dorsal-root ganglia adjacent to the spinal cord. Here the virus stays in an inactive stage.

What are the smallest blood cells in the frog?
Tamiku [17]

Answer:

Unlike typical mammalian red blood cells, those from amphibians, such as frogs, contain a DNA-bearing nucleus that is visible in the center of the cell. The circulatory system of amphibians is rather unusual, their hearts having three chambers, two atria, and a single ventricle.

NegativePositive

Positive

The design of the amphibian circulatory system is curious because blood accumulates oxygen in the lungs and is then returned to the heart before being pumped into the rest of the circulatory system. Therefore, a mixing between oxygenated and deoxygenated blood occurs as blood returning to the heart from the lungs is mixed with incoming blood from the body. Frogs handle this situation by having a very slow metabolism and by absorbing some oxygen through their skin. In addition, the ventricle does have some directional control over the distribution of the blood.

Negative

The presence of a nucleus in amphibian red blood cells allows researchers easy access to large quantities of amphibian DNA. Frog blood has both a solid and a liquid portion. The liquid plasma carries solid elements such as red and white blood cells. Blood can be collected from frogs and the red blood cells isolated by centrifugation. After removal of the residual plasma, purified cells can be treated with specific enzymes and detergents to digest the cellular envelope and release DNA from its protein complex. The DNA is then useful for scientific studies and experiments.

After DNA replication, __________. See Section 6.2 (Page 116) . After DNA replication, __________. See Section 6.2 (Page 116) .
ozzi

Answer:

each of the two daughter DNA molecules contains one strand from the original DNA molecule and one newly synthesized strand.

Explanation:

DNA replication is a semi-conservative process. The two parental DNA strands are separated from each other by the action of helicases. The separated DNA strands serve as the template. Primase enzyme forms primers which are elongated by DNA polymerase enzymes. These enzymes elongate the primer by the addition of deoxynucleotides complementary to the sequence of the template DNA strand.

Therefore, DNA replication forms two DNA double helices from one parental DNA molecule. Each of the daughter DNA molecules contains one parental DNA strand and one newly formed DNA strand making the process semi-conservative.
