What do host cells provide for viruses?
a. ATP
b.
c. ribosomes
d. all of the above

Introduction:
The viruses are small biological infectious agents that can replicate inside the cells of other living organisms only. They are simple particles that require a host cell to replicate and survive.
Answer to Problem 1TYK
Correct answer:
The host cells provide ATP (adenosine triphosphate), nucleotides, amino acids, and ribosomes to the viruses for their growth and development.
Explanation of Solution
Explanation/Justification for the correct answer:
Option (d) is given as all of the above. They cannot make their own ATP, nucleotides, amino acids, and ribosomes. The virus cannot synthesize their own proteins. The virus enters the host cell to survive. The host cell provides the energy (ATP) to the viruses inhabiting in it. It also provides nucleotides for nucleic acid synthesis, and amino acids and ribosomes for the protein synthesis in the viruses. Hence, Option (d) is correct.
Explanation for the incorrect answer:
Host cell provides all the three entities ATP, nucleotides, and amino acids for viral growth and development. It does not provide solely ATP, nucleotides and amino acids, and ribosomes. Hence, all the three options (a), (b), and (c) are incorrect.
Therefore, it can be concluded that the host cells provide energy, proteins, nucleotides, ribosomes, and amino acids to the viruses for their development and growth.

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell.
