ECOR1 cuts Plasmid T into 3 pieces. Feeling grumpy at your professor (), you decide to take a random enzyme and mix it with a random plasmid, Plasmid M (for mystery). You run a gel and see one very large band at the top of the gel. Which of the following is NOT likely: a. Plasmid M has zero restriction sites for any enzyme b. The enzyme and plasmid are not the same as Ecor1 and Plasmid T c. Plasmid M wasn't cut at all d. The plasmid does not have a restriction site for the mystery enzyme

Which THREE statements are true about targetting proteins to the nucleus? A) The nuclear localization sequence is emoved after targetting to the nucleus? B) The nuclear localization sequence is ocated almost anywhere in protein amino acid sequence. C) The nuclear localization sequence contains several consecutive basic (Arg or Lys) residues. D) Aln the cytoplasm, a protein with an appropriate nuclear localization signal (NLS) is bound by a complex of importin ⍺ and ⍴. E) Importins a and B and CAS are degraded in the nucleus. F) The nuclear localization sequence usually contains around 20 amino acids.

Regarding gene regulation, which of the following statements are TRUE Prokaryotic gene regulation involves repressor proteins that respond to cell conditions by preventing DNA Polymerase from beginning transcription of the gene Prokaryotic gene regulation involves repressor proteins that respond to cell conditions by preventing RNA polymerase from beginning transcription of the gene Negative regulation involves repressor proteins that respond to cell conditions to actively repress (prevent) DNA Polymerase from beginning transcription of the gene (or operon) by binding onto the DNA at the operator site None of the those All of those

If you do not know how to use a microscope properly, you will have a difficult time finding specimens/cells in this unit. The letter "e" is something everyone should be familiar with (or at least I hope so). We all know that an "e" is round with a line connecting the upper half. Today, you will use that knowledge to determine how a microscope works. You have two objectives to fulfill by the end of this lab: 1. Properly use and focus a microscope from a low power to a high power objective lens. 2. Determine what happens to the image of a specimen in the microscope.

QUESTION 2 The following are all steps involved in the preparation of tissue sections. Place them in the correct order. Sectioning: The tissue is surrounded by hard paraffin and trimmed to a trapezoid shape. A microtome is used to cut thin slices of tissue Clearing: the dehydrating agent is replaced with a substance called an antemedium. Fixation: this step preserves tissues without any major alterations in structure or morphology Infiltration and embedding: Tissues are placed in a solution of molten paraffin Dehydration: the removal of water from the tissue.
