Chapter 48, Problem 1IQ
Summary Introduction
To determine: The way by which nuclear DNA can be obtained from a mature red blood cell.
Introduction: Nuclear DNA is the main genetic material of most eukaryotic organisms that encode the majority of the activities of the organisms. The double-helical structure of DNA consists of

Read the question carefully first
Answer the question-1 given figure below according to the question (a) (b) (c) with step by step
clear explanation.
Question 1
Figure below shows red blood cells placed in three solutions of different tonicity.
HEMOLYSIS
CRENATION
HEMOGLOBIN
Solution A
Solution B
Solution C
(a) Which solution, A, B or C, is hypertonic? What is a hypertonic solution?
(b) Explain what has happened to the cells in solution C.
(c) Plant cells will also change when placed in different solutions. Describe what would happen to a plant cell when
it is placed in a hypotonic solution. Explain why this is different from what happened to the red blood cells in
the above figure.

A research student is investigating artificial substitutes for human blood inemergency blood loss situations. For example, a person has suffered a traumaresulting in a large open wound and has lost a large volume of blood. The wound hasbeen temporarily closed and blood loss has been slowed.Consider the above scenario to answer the following questions in sentence format.a. While blood supports many functions, what would be the primary short-termpurpose of artificial blood in this scenario?b. What characteristics would artificial blood need to have in order to functionwell in the body to address acute blood loss?c. What type of tissue is blood?

Patient Encounter Part 3
The pretreatment workup is summarized below.
Pathology: 47-year-old female with new diagnosis of
infiltrating intraductal adenocarcinoma involving the left
breast and regional node. Further tests on tumor samples
indicated ER (8%), PR (negative), HER2 (negative), Ki-67 (72%),
and grade (poorly differentiated). Intrinsic subtype (luminal B,
HER2-negative).
Radiology: FDG-PET/CT indicated a 5.3 x 2.5 cm mass in the
left breast which appeared to extend to the epidermis of the
skin; one node in the left axilla was also involved with tumor.
No other evidence of distant disease was visualized.
Laboratory: CBC, liver, and kidney function tests WNL, alkaline
phosphatase and calcium are normal also.
Stage: IB (T, N, M,)
List the most important prognostic factors in this patient with
newly diagnosed breast cancer.
Assess the patient's level of risk for relapse.

- please answer all parts if possible. A question from histologyarrow_forwardSouthern Blotting & Detection of sickle cell disease: Please interrupt the following results and draw a Punnett square, and answer the questions. •Discuss figures (gel figure and Punnett square) one by one. •You must provide discussion for each lane of the gel, how you make out normal, carrier, disease (allelic patterns- why so?), control IMPORTANT POINTS TO REMEMBER: •Homozygous (one band)- the size of the band (lower or higher in the gel) determines if normal (both alleles cut by MSt II, hence band lower) or diseased (both alleles uncut and hence at the higher position in gel) •Heterozygous (two bands in the same lane) denotes a carrier (lower band from normal allele which is cut by RE & upper sickle cell allele band is uncut)arrow_forwardPlease answer , thank youarrow_forward
- Immunology question: Using cytometry to stain a lymph node sample from a patient having a bacterial infection with a green fluorescent labeled anti-MHC I antibody and a red fluorescent-labeled anti-B7 antibody, what are the cells that are in each quadrant of the cytometry plot? Note that the upper left is high in red and no green, the upper right is high red and high green, the lower left is none of red nor green, lower right is only high green. My personal understanding Is: UL: None: since there are no cells express B7 in lymph nodes without being APC. UR: Activated antigen-presenting cells LL: None APC cells including T cells, FDC; pathogens, etc. LR: Non-activated APC cells. (Question, does all cells express MHC I ? if that's the case there should be a lot more)arrow_forwardMust be used for reconstitution of human or bovine thrombinarrow_forwardChoose correct option and explain shortly. Question:- Which of the following is the best description of how you can measure white blood cells (WBCs) using the fluorescent light application of a flow cytometer? (a) How granular each cell is and what surface proteins they express, but not how big they are (b) How granular each cell is, but not how big they are or what surface proteins they express (c) How big each cell is, but not how granular they are or what surface proteins they express (d) How big and how granular each cell is, but not what surface proteins it expresses (e) How big each cell is and what surface proteins they express, but not how granular they are (f) What surface proteins each cell expresses, but not how big or how granular they arearrow_forward

B) How do forward versus side scatter plots enable the characterization of different types of blood cells in the blood of a patient? How does this relate to a potential diagnosis of acute leukemia? C) How do you determine if a patient has B cell versus T cell Leukemia? Why is it important to know?arrow_forwardDiscuss the similarities and differences between cytopenia and neutropenia.
