- FtsZ proteins direct the formation of a ________ that will eventually form the new cell walls of the daughter cells. a. contractile ring b. cell plate c. cytoskeleton d. septumAll of the following are true of integrins except (a) they are receptor proteins (b) they help organize the cytoskeleton (c) they are part of the ECM (d) they are important in cell signaling (e) they are located in the plasma membraneFigure 37.5 Heat shock proteins (HSP) are so named because they help refold misfolded proteins. In response to increased temperature (a “heat shock"), heat shock proteins are activated by release from the NR/HSP complex. At the same time, transcription of HSP genes is activated. Why do you think the cell responds to a heat shock by increasing the activity of proteins that help refold misfolded proteins?
- Biologists have long been interested in the effects of radiation on cells. In one experiment, researchers examined the effect of radium on mitosis of chick embryo cells growing in culture. A population of experimental cells was examined under the microscope for the number of cells in telophase (as a measure of mitosis occurring) before, during, and after exposure to radium. The results are shown in the Figure. What is the effect of radium exposure on mitosis? Source: R. G. Canti and M. Donaldson. 1926. The effect of radium on mitosis in vitro. Proceedings of the Royal Society of London, Series B, Containing Papers of a Biological Character 100:413419.What is necessary for a cell to pass the G2 checkpoint? a. cell has reached a sufficient size b. an adequate stockpile of nucleotides c. accurate and complete DNA replication d. proper attachment of mitotic spindle fibers to kinetochoresDescribe the similarities and differences between the cytokinesis mechanisms found in animal cells versus those in plant cells.
- FtsZ proteins direct the formation of a ___________ that will eventually form the new cell walls of the daughter cells. contractile ring cell plate cytoskeletom septumControl of gene expression in eukaryotic cells occurs at which level(s)? a. only the transcriptional level b. epigenetic and transcriptional levels c. epigenetic, transcriptional, and translational levels d. epigenetic, transcriptional, post-transcriptional, translational, and post-translational levelsSome cancer cells are insensitive to typical chemotherapy. Research into the mechanisms underlying this insensitivity uncovered an ability by these cells to pump the treatment drug out of the cell against its concentration gradient. Additional drugs have been developed that inhibit the pump, thus trapping the chemotherapeutic agent inside to promote cancer cell destruction. The Figure shows what happens when two types of cells are treated with a 3H-labeled anti-cancer drug, paclitaxel. Which set of cells (A or B) would be described as resistant to the cancer treatment? Explain your answer. What type of transport are the resistant cells using?
- Chromatin decompaction is a preliminary step in gene expression (Figure 29.48). How is chromatin decompacted?The Adaptive Immune Response Is a Specific Defense Against Infection Researchers have been having a difficult time developing a vaccine against a certain pathogenic virus as a result of the lack of a weakened strain. They turn to you because of your wide knowledge of recombinant DNA technology and the immune system. How could you vaccinate someone against the virus, using a cloned gene from the virus that encodes a cell-surface protein?Figure 9.8 HER2 is a receptor tyrosine kinase. In 30 percent of human breast cancers, HER2 is permanently activated, resulting in unregulated cell division. Lapatinib, a drug used to treat breast cancer, inhibits HER2 receptor tyrosine kinase autophosphorylation (the process by which the receptor adds phosphates onto itself), thus reducing tumor growth by 50 percent. Besides autophosphorylation, which of the following steps would be inhibited by Lapatinib? Signaling molecule binding, dimerization, and the downstream cellular response. Dimerization, and the downstream cellular response. The downstream cellular response. Phosphatase activity, dimerization, and the downsteam cellular response.
