Hello. This question is incomplete. The full question is:
"Recently, researchers uncovered the molecular structure of a key protein that retroviruses use to multiply. This was a significant step toward _____. A.) producing lifelike artificial limbs B.) providing healthcare for all people C.) stopping the spread of the HIV/AIDS virus D.) using biotechnology to vaccinate children "
Answer:
D.) using biotechnology to vaccinate children
Explanation:
Retroviruses are DNA viruses and, like any other virus, are obligatory parasites causing harm to their hosts. These viruses are capable of infecting birds and mammals, causing several different diseases such as AIDS and some types of cancer because they have oncological genes.
Although the AIDS virus is a retorvirus, the discovery of a molecular structure of a key protein that retroviruses use to multiply would not be enough to stop the spread of HIV, but this discovery could be effective in promoting vaccines that can decrease the incidence of this virus on the human organism.
