A chromosome has undergone a translocation that has completely deleted its centromere region, preventing association with spindl
kobusy [5.1K]

Answer:

<h2>The cell will not pass the M checkpoint because its chromosomes will not associate with spindle fibers. or if the cell goes complete division, then the homologous chromosomes will go into either daughter cell.</h2>

Explanation:

 As in the cell cycle, there are various checkpoints, which checks the cell in many steps like G1/S checkpoint, G2, M  etc. They check the integrity of the genome, if there is any defect in the DNA/chromosome, it arrest the cell cycle.

Centromere is the region on the chromosome which binds with spindle fibers and is used in the separation of chromosomes during anaphase of cell cycle. If there is deletion of centromere, then the separation of chrmosome will be affected. Then the homologous chromosome can either go into one of the daughter cell, so one cell will get 2n+1 and other will get 2n-1.

100 points! Complete the simple sugar molecule Glucose. Please fill out the diagram of the molecule and provide the link of the
Valentin [98]

Answer and Explanation:

Glucose is a hexose with six carbon atoms. It is also an aldose, meaning that it has an aldehyde group, CHO in its first carbon atom. The molecule also has hydroxyl groups, OH linked to the carbon atoms.

Its linear structure shows six carbons united in a line. One of its carbon atoms is linked to a carbonate group, H-C=O. The other five carbons are linked to the hydroxyl groups, OH.                

In an aqueous solution, the glucose molecule turns to the ringed or cyclic structure, as a result of the reaction among the first carbon and the oxygen of the hydroxyl group linked to the fifth carbon.  

<em>You will find the complete glucose molecule in one of the attached files (named glucose), plus the linear and cyclic structure in the other file (named glucose1).   </em>

Which parts of the monomers involved in the dimer formation​
vazorg [7]

Answer:

A dimer (/ˈdaɪmər/) (di-, "two" + -mer, "parts") is an oligomer consisting of two monomers joined by bonds that can be either strong or weak, covalent or intermolecular. The term homodimer is used when the two molecules are identical (e.g. A–A) and heterodimer when they are not (e.g. A–B).

Patients with chronic pain may be more sensitive to pain and other stimuli true or false
Zielflug [23.3K]
<span>This is true<span> as patients that are in chronic pain are sensitive to acute recurrences of pain whether in the same body part or in different areas of the body. While pain is considered a sensation, and sensations are desensitized after prolonged exposure; the opposite is true for pain as people suffereing from chronic pain becomes more sensitive to pain.

</span><span><em>This principle is adapted from the 9 core principles of pain assessment (Lewis's Medical-Surgical Nursing, 2017)</em>
<em>1. Patients have the right to appropriate assessment and management of pain.</em>
<em>2. Pain is always subjective</em>
<em>3. Physiologic and behavioral signs of pain are not sensitive or specific for pain</em>
<em>4. Pain is an unpleasant sensory and emotional experience.</em>
<em>5. Assessment approaches, including tools, must be appropriate for the patient population.</em>
<em>6. Pain can exist even when no physical cause can be found</em>
<em>7. Different patients experience different levels of pain in response to comparable stimuli.</em>
<em>8. Patients with chronic pain may be more sensitive to pain and other stimuli</em>
<em>9. Unrelieved pain has adverse physical and psychologic consequences. Acute pain that is not adequately controlled can result in physiologic changes that increase the likelihood of developing persistent pain.</em></span></span>
