3. A researcher discovered that a certain cell does not have any nucleosome modifiers What is the effect of missing

4. Which of the following is true regarding the mRNA of a eukaryotic glucose transporter and a spliceosome RNA? A. Both are protein coding RNAs B. Both are ribozyme C. Both are transcribed by the RNA pol II D. Both are spliced by the spliceosome E. Both are exported to the cytoplasm

1.In a cell culture you are tracking cell division and DNA replication. You start with 100 cells, and let the cells divide two rounds with fluorescent nucleotides present in the media, instead of normal nucleotides. This allows for the visualization of the DNA under a fluorescence microscope. After two rounds of division, you remove the fluorescent nucleotides, and let the cells divide one more round.  How many NON-fluorescently labeled cells do you expect to find? Select one: a.800 b.100 c.400 d.0 e.200   2.  Which of the following are protein - RNA complexes? a.Polymerase b.Ribosome c.aminoacyl trna synthetase d.Spliceosome

5. In what organelle of the cell are amino acids synthesized from mRNA?

35. Which of the following statement relating to the cell nucleus is inaccurate?  a. all body cells are nucleated b. the nuclear envelope is a non-porous double-layered membrane c. contains nucleoli that are involved in tRNA synthesis d. a and b e. a, b, and c

5. Explain the difference between a centriole and a centromere
