An aide asks the nurse why people who have neurofibromatosis will show varying degrees of the disease. Which genetic principle should the nurse explain to the aide? Selected Answer: b. Expressivity Correct Answer: b. Expressivity Question 2 1 out of 1 point s Why is potassium able to diffuse easily in and out of cells? Selected Answer: c. Because the resting plasma membrane is more permeable to potassium Correct Answer: c. Because the resting plasma membrane is more permeab...

Growth factors stimulate what? (A) cyclin production. (B) the cell to skip the S and G1 phases of interphase and undergo mitosis directly. (C) Cdk's to synthesize enzymes that digest cyclins. (D) the cell to ignore the checkpoints of the cell cycle. (E) NONE OF THE ABOVE - Answer (A) cyclin production What is a major difference between mitosis and meiosis? (A) Meiosis produces two daughter cells instead of the four daughter cells produced in mitosis. (B) Meiosis produces genetically ide...

1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus, the nucleus should be observed. A single circular chromosome called a prokaryote contains free-floating nucle...

A - Alanine (1 letter) Activation of enzymes through ligand binding: why would this be useful? - The binding of a ligand to an allosteric site of a multimeric enzyme often induces positive cooperativity, that is the binding of one substrate induces a favorable conformation change and increases the enzyme's likelihood to bind to a second substrate. Ala - Alanine (3 letter) Arg - Arginine (3 letter) Asn - Asparagine (3 letter) Asp - Aspartic Acid (3 letter) Barr body and relation to hete...

Similarities between eukaryotic and prokaryotic cells 1) Semi-conservative 2) Bidirectional Prokaryotic cells 1) Circular DNA 2) Single origin of replication Eukaryotic cells 1) Linear DNA 2) Multiple origins of replication New strands are always synthesized from: 5' --> 3' end of each strand Template strand is read: 3' --> 5' Chain extension occurs: by adding a dNTP to free 3' end of growing polynucleotide chain DNA polymerase DNA s...
