Answer:
true
Explanation:
A particular enzyme can function over a wide range of temperature and pH. Temperature can change the activity of an enzyme.
The answer is D. The formation of protein can be divided into two major parts. First one is transcription which means converting the DNA to the mRNA. This takes place in the nucleus. And then the mRNA will be transported to ribosomes (A is not correct) and be translated to protein. This will take place in the cytoplasm. So the B and C is not correct. Vacuoles are in the plant cells.
Answer:
Explanation:
Regarding the HIV cycle, we fear two types of cycles: lytic and lysogenic. In the first mentioned above, the proteins that make up the capsid will replicate. These unite around the nucleic acid molecules, producing new viruses. As a result of this event, lysis occurs, that is, the infected cell breaks down and new bacteriophages are released. Symptoms caused by a virus that reproduces this way in a multicellular organism appear immediately. In this cycle, viruses use the cell's biochemical equipment (ribosome) to make their protein (capsid).
On the other hand, there is another cycle in which the production of viral components is shut down indefinitely. This type of multiplication is called lysogeny or lysogenic cycle and is a well established phenomenon for bacterial viruses. The symptoms caused by a virus that reproduces itself through the lysogenic cycle in a multicellular organism may take time to appear. Diseases caused by lysogenic viruses tend to be incurable, such as AIDS and herpes. For this reason that after this initial symptoms, like flu, is going to disapear and other symptoms of HIV infection will lie dormant for many years.
