Prokaryotes differ from eukaryotes in terms of cell complexity.
<h3>Differences between prokaryotes and eukaryotes</h3>
Prokaryotes refer to living organisms whose bodies are made from prokaryotic cells. Eukaryotes, on the other hand, are organisms made from eukaryotic cells.
Prokaryotes differ from eukaryotes in the following ways:
- Prokaryotes lack a nucleus while eukaryote organisms have one or more nuclei. The genetic materials of prokaryotes are arranged as nucleoids and lie freely within the cytoplasm.
- In terms of size, prokaryotic cells range from 0.1 to 5 micrometers. Eukaryotic cells range from 10 to 100 micrometers.
- Prokaryotic cells usually have cell walls. Some eukaryotic cells have cell walls, while some do not.
- The ribosome size of prokaryotes is around 20 nm while that of eukaryotes varies from 25 nm to 30 nm.
- In terms of evolutionary advancement, eukaryotes are more advanced than prokaryotes.

Answer: True
HIV infects a type of white blood cell in the body's immune system called a T-helper cell (also called a CD4 cell). These vital cells keep us healthy by fighting off infections and diseases. HIV cannot reproduce on its own. Instead, the virus attaches itself to a T-helper cell and fuses with it (joins together).
Explanation:
T-cells, the thymus cells, work in a similar way but destroy infected cells rather than manufacture antibodies. In HIV infection, the body mounts a very strong antibody response in the first few weeks that partially works, bringing the viral load down from millions to, on average, about 50,000 copies/ml.
In the beginning <span>of the RNA strand as a cap, a modified guanine nucleotide is added. After this, there is a removal of those segments of the RNA strand that do not actually code for the protein. And those RNA’s segments that do code for the protein are reconnected. And forking a tail, extra adenine nucleotides are added to the end of the RNA strand. The mRNA or messenger RNA which is already completed will then leave the nucleus. This whole process is called the RNA processing. Before the RNA copy of a protein encoding can be transported out of the nucleus and translated into protein, it must be first be modified in several ways. A precursor of mRNA, pre-mRNA is the primary transcription product of a gene. </span>
