Retroviruses also have the enzyme reverse transcriptase, which allows it to copy RNA into DNA and use that DNA "copy" to infect human, or host, cells.
What is DNA?
Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells. The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a tiny quantity of DNA in the mitochondria (where it is called mitochondrial DNA or mtDNA). Cellular organelles called mitochondria transform the energy from food into a form that can be utilized by cells.
Adenine (A), guanine (G), cytosine (C), and thymine (C) are the four
chemical bases that make up the code that stores the information in DNA (T). More than 99 percent of the 3 billion bases that make up human DNA are the same in every person.

Answer:
This question lacks options, the options are:
a. Ribosomes
b. Centrioles
c. Mitochondria
d. Peroxisomes
The correct answer is a.
Explanation:
A ribosome is a complex macromolecular structure in the cell (a cellular organelle) that is involved in protein synthesis
. Osteoblasts are cells that produce the osteoid substance (fibers and fundamental substance). Osteoblasts synthesize the organic component of the bone matrix (type I collagen, proteoglycans, proteins involved in cell adhesion, osteocalcin and growth factors) and control the deposition of mineral salts. They have a powerful ribosomal apparatus, consistent with the intense synthesis of proteins they develop. Of these, the most important quantitatively is collagen, but they also synthesize other proteins, among which it should be noted, osteocalcin. In addition to synthesizing proteins, the osteoblast directs bone mineralization. The non-mineralized bone tissue is called «osteoid», and is formed by layers that are synthesized from depth to surface, being defined by the different orientation of the collagen fibers in each of them.
