Question
Chapter 13, Problem 1ITD
Summary Introduction

To review:

The necessity to define the data in terms of adduct quantity in µg (micrograms) of DNA and not in the form of in total quantity of adduct.

Introduction:

DNA is a crucial component of chromosomes. DNA (deoxyribonucleic acid) carries the genetic information that passes from parents to the offspring. The changes in the external or internal environment may result in the mutation of chromosomes, which may cause genetic defects.

The dominant condition elliptocytosis causes red blood cells to become misshapen into oval-shaped cells. One of the genes responsible for the abnormal shape encodes the band 4.1 protein that together with ankyrin and other scaffold proteins creates and maintains the spherical concave shape of a normal red blood cell. The gene for band 4.1 protein, EPB41, is found on the p arm of chromosome 1. This is very close to the gene encoding the red blood cell Rhesus (Rh) blood type, either phenotype + (dominant) or - (recessive), with a recombination frequency of 2%. This means that 98% of the time alleles for these two genes are linked and are transmitted together. Diane and Jack are siblings, and both have elliptocytosis and Rh+ blood type. Due to the elliptocytosis, both had emergency splenectomies after having severe anemia. Their younger brother, Devonté, has not yet shown signs of elliptocytosis, but has Rh- blood. André, their dad, also has elliptocytosis and Rh+ blood; while their…

  • Fragile X syndrome, caused by a change in the FMR1 gene, is the most common form of intellectual disability. In patients with this syndrome, a small part of the gene is repeated several times in one area of the chromosome. This defect in the gene makes the body unable to produce adequate amounts of a protein needed for normal brain functioning. In males, this syndrome causes a moderate intellectual disability, and in females, a mild intellectual disability. A family that exhibits Fragile X syndrome is shown in the pedigree. In the pedigree, squares represent males and circles represent females. Shaded symbols represent a person with the disorder.   Which of the following correctly predicts the outcome if offspring 11 mated with a homozygous normal female, based on the inheritance pattern shown in the pedigree? The male offspring would exhibit Fragile X syndrome because Fragile X is an X-linked recessive trait. The female offspring would exhibit Fragile X syndrome because Fragile X…
    A subset of colorectal cancers is associated with mutations in the Mut genes which code for proteins involved in repairing DNA mismatches. How would mutations in the Mut genes affect the DNA of an individual?
    Most cells are unable to copy the ends of chromosomes, and therefore chromosomes shorten with each cell division. This limits the number of times a cell can divide. In germ cells and stem cells, however, an enzyme called telomerase lengthens the telomeres and prevents chromosome shortening. Thus, these cells are not limited in the number of times they can divide. All cells have the gene for telomerase, but most somatic cells don’t express it, and they produce no telomerase. Why don’t somatic cells express telomerase and have unlimited division?
