Yes. This a complicated process. They are called retrovirus because they have to work backwards compared to other viruses. Once inside the cell, they highjack the cell the same way as other viruses. These retroviruses are important to understand as so many important diseases are caused by them.
The retroviruses are enveloped viruses that have two complete copies of (1) sense RNA . They also contain the enzyme reverse transcriptase, which uses the viral RNA to form a complementary strand of DNA, which is then replicated to form a dsDNA. This reaction is exactly the reverse of the typical transcription step (DNA -> RNA) in protein synthesis. For virus replication to continue, the newly formed DNA must be transcribed into viral RNA that will function as mRNA for viral protein synthesis and be incorporated into new virions. To do so, the DNA must first migrate to the host cell nucleus and become incorporated into chromosomes of host cells. Such integrated viral DNA is known as a provirus. Retroviruses cause tumors and leukemia in rodents and birds, as well as in humans. The human retroviruses invade immune defense cells called T lymphocytes and are referred to as human T cell leukemia viruses (HTLV). Both HTLV-1 and HTLV-2 are associated with malignancies (leukemia and other tumors), whereas the human immunodeficiency virus (HIV- 1 and HIV-2 strains) causes acquired immune deficiency syndrome (AIDS)
A retrovirus contains reverse transcriptase. This enzyme allows the virus to convert its RNA genome into DNA once inside a host cell, integrating the viral DNA into the host cell's genome for replication. HIV is an example of a retrovirus.
Yes, bacteria like Escherichia coli (E. coli) can be genetically engineered to produce human proteins through a process called recombinant DNA technology. This involves inserting the gene encoding the human protein into the bacterial genome, which then allows the bacteria to produce the desired protein.
Bacteria have been engineered to produce proteins and drugs using recombinant DNA technology. This involves inserting genes encoding the desired protein or drug into the bacteria's genome, which then enables them to produce these compounds efficiently on a large scale for therapeutic use in fighting diseases.
Around 2000 proteins are involved in the regulation of genes in the developing cell in a human body, though there is an estimated 2600 DNA binding proteins, but only around the 2000 is required to account for regulating all the genes in each of our genome during development. its about 10% of the total protein information we have in our genes because the human genome contains information to approx. 25000 proteins.
The number of nitrogen bases in a bacterial genome can vary depending on the species of bacteria. On average, a bacterial genome may contain around 1 to 10 million nitrogen bases. These nitrogen bases make up the genetic code of the bacteria and are responsible for encoding the information necessary for the bacteria to function and reproduce.
No, HIV is a retrovirus - it has a single-stranded RNA genome.

In gene therapy, a retrovirus is engineered to contain a particular RNA sequence that is to be inserted into the target host's genome lysogenically. That retrovirus also contains reverse transcriptase. When the retrovirus is introduced to the host, it spreads throughout the host's system, infecting cells harmlessly, and introducing the new RNA sequence and reverse transcriptase. This converts the RNA to DNA, and the new DNA (new gene) is integrated into the host's DNA (genome).
No. Though measles contains an RNA genome like retroviruses, it does not have the distinctive enzyme reverse transcriptase, and therefore does not change its genome to DNA before transcription.

The genome is the sum of an organisms genetic information. The information in the genome is translated into the proteins which are the structural and functional componants of life. Thus, very useful :P
Amino acids are the building blocks of proteins, not DNA, which makes up the genome.
A retrovirus is an RNA virus that is replicated in a host cell via the enzyme reverse transcriptase to produce DNA from its RNA genome. The DNA is then incorporated into the host's genome by an integrase enzyme. The virus thereafter replicates as part of the host cell's DNA. Retroviruses are enveloped viruses that belong to the viral family Retrovirida.
