If the HIV did not have a reverse transcriptase enzyme, then which of the following would apply? Select one: a. The virus can make use of the reverse transcriptase enzyme from the host cell to convert its RNA into DNA b. Viral particles will be produced without reverse transcriptase enzyme since the original HIV is an RNA virus and needs to assemble RNA ant coat proteins together c. The virus will manufacture its proteins from its RNA using translation and ribosomes from host cell d. Provirus will not be formed and assembly of viral particles will never occur e. The virus will not be able to recognise the host cell and therefore entry into the cell is blocked

Viruses are made up of the same biomolecules as cellular organisms (DNA, RNA, proteins, lipids, etc.), which are synthesized through enzymatic dehydration reactions from building blocks and disassembled by enzymatic hydrolysis. They infect cells and replicate themselves using resources from the host cells. Scientists discovered a previously unknown strain of virus in the tropical Pacific Ocean and it can infect higher-order eukaryotes. Initial analysis revealed that the virus is mainly composed of nucleic acids, proteins, and lipids. Chemical analysis after complete hydrolysis revealed the following building blocks (by weight): Chemical components Nucleosides Amino acids Lipids, phosphates, and carbohydrates Percentage by weight 20 30 50 Analysis of percentages of nucleosides yielded the following results (by molar ratio): Nucleosides A G T C U Percentage by mole 19 29 19 29 4 Which of the following events mostly involves hydrolysis reaction after the virus infects…

I need help with these questions I’ve completed for biology homework. So basically it says “A company was testing a new drug it thought it would help decrease the risk of transmission of virus from mother to fetus. In an experiment to test the drug, an investigator gave 400 pregnant female rats a small dose of the experimental drug and inocululated each type of virus known to causes disease in rats. At the same time, 400 other pregnant rats were given only the virus. All rats were given the same food and kept in similar cages. Of the rat pups born to females that received both the virus and the drug. 203 showed no symptoms of the disease; 205/rat pups born to the virus-only females showed symptoms. I wrote down the hypothesis I said the drug will decrease the rate of transmission of the virus from mother to fetus Then I wrote down independent/dependent which was the drug being independent and the transmission of virus being dependent Then I wrote the controlled variables…
