Puzzling Proteins
All cells use DNA as a blueprint for producing more cells, and viruses use either DNA or RNA. Before the discovery of prions, however, no infectious agent had ever been discovered that completely lacked genetic material composed of
In addition to lacking genetic material, prions also lack another component that all other infectious agents possess: a surrounding membrane. What kinds of molecules are involved in the construction of membranes?

transcriptase enzyme. What can you conclude about replication of this virus?

Its replication depends entirely on cellular enzymes
Its replication is entirely independent of cellular enzymes

radiation, X-rays

Can u help me to explain to me, please?
You are studying a new retrovirus. The viral protein (X) appears to play a role in the export of the viral genomes to the
cytoplasm. Protein X brings viral DNA to the cytoplasm and returns back to the nucleus after genome export is complete.
Researchers have developed a new drug for the virus. Following treatment with the new drug, the viral protein stays in the
nucleus and cannot export the viral genomes. What is the most plausible and logical function of the drug? Use your
knowledge of nuclear transport to answer this question.
O A. The drug inhibits the binding of the viral protein and the viral genomes to the import receptor.
B. The drug inhibits the binding of Ran-GTP to the nuclear export receptor in nucleus.
C. The drug promotes the Ran GAP activity.
D. The drug blocks the NLS on the viral protein.

- MRSA has emerged as a serious infectious disease, with the first case of methicillin-resistant S. aureus being detected in 1961. Why are medical professionals so concerned when antibiotics exist that can kill MRSA? MRSA can transfer methicillin-resistance to other bacteria Patients are not treated with correct antibiotics rapidly enough to prevent serious illness MRSA could acquire additional antibiotic resistance genes from other bacteria to become a “super bug." All of the above.arrow_forwardWhich statement is true of viroids? They are single-stranded RNA particles They reproduce only outside of the cell They produce proteins They affect both plants and animals.arrow_forwardViruses replicate by entering a cell and using the host cell's enzymes to produce more copies of itself. SARS-COV2 is a spherical virus that has been observed to be as small as 50 nm in diameter. If we approximate a human epithelial cell to be a cylinder with a 58 um height and 5 um diameter, what is the maximum number of SARS-COV2 viruses that could fit inside the cell?arrow_forward
- 1. The SARS-CoV-2 virus (causing Covid-19) has an RNA genome, which is replicated using an RNA-dependent RNA polymerase (RdRp). The structure below shows a drug that was recently developed as a treatment for infection with SARS-CoV-2 (a) Which molecule normally found in a cell does it most resemble? (You can ignore the part of the structure highlighted with a red box. This is removed by hydrolysis when the drug enters the cell). (b) Suggest a mechanism by which this molecule might inhibit infection. (c) Why is this drug unlikely to have major effects in the host? HN OH OHarrow_forwardBacteria have evolved numerous mechanisms to prevent the invasion of foreign viral DNA (see Bacterial Defense Mechanisms). Yet clearly some bacteria have evolved competence, the ability to take up foreign DNA from the environment. Why do bacteria take up naked DNA from the environment and yet exclude DNA from viruses?arrow_forwardThe 1918 influenza strain killed millions of people world-wide. After recovering the virus from preserved lung tissue and sequencing the genome, which of the scientific findings did NOT account for the viruses lethality in humans? The hemagglutination protein was associated with high lung damage. The virus came directly from birds, without first circulating in pigs. The virus was independent from a cellular protease for cell entry, and utilized neuraminidase instead. The virus came from bats.arrow_forward
- Which feature (antibiotic target) of bacteria seems to be the most resistant to antibiotics? Why might that be?arrow_forwardHelp mearrow_forwardA bacteriophage has inserted its DNA into a bacterial host and replicated as a part of the host’s genome for several generations as the host reproduces. For this virus to assemble more infectious viral particles, what must it do? Switch to the lysogenic cycle of replication Switch to the vicious cycle of replication Purposefully mutate its own genes Switch to the lytic cycle of replicationarrow_forward
- The DNA and RNA polymerases of viruses are typically more prone to making errors in the polymerization than are regular cellular polymerases. Why would be viruses be more tolerant of errors than are cells?arrow_forwardWhich of the following is a difference between a viroid and a virus? O viroids contain some genes important for their own replication while viruses rely entirely on host cell enzymes for their replication viroids are alive and viruses are not O viroids are not infectious particles and viruses often cause disease O viroids are composed solely of nucleic acid while viruses are composed of nucleic acid surrounded by a protein coat O viroids infect only plants while viruses infect only animals and prokaryotesarrow_forwardIn 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a persons own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwangs group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?arrow_forward
