Retroviridae is a family of enveloped viruses that replicate in a host cell through the process of reverse transcription. A retrovirus is a single-stranded positive-sense RNA virus with a DNA intermediate and, as an obligate parasite, targets a host cell.ithin the cell, reverse transcriptase creates a complementary strand of DNA from the retrovirus RNA and the RNA is degraded; this strand of DNA is known as cDNA (4). The cDNA is then replicated, and the two strands form a weak bond and go into the nucleus (5).
Nucleic Acids. The third group of macromolecules found in cells contain some of the largest molecules of the body-these are the nucleic acids. There are two major groups of nucleic acids, ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) .Each group is composed of long chains of building block molecules known as nucleotides.There are four different nucleotides used in the formation of nucleic acids, these are adenine, thymine (uracil instead of thymine is found in RNA), guanine and cytosine (see Figure 11).ach group is composed of long chains of building block molecules known as nucleotides.
