Chapter 16.4, Problem 1TYK
Summary Introduction
Introduction:
The epigenetic modifications involve acetylation, phosphorylation, glycosylation, and so on. These changes can take place in the cisternae of the rough endoplasmic reticulum (RER), cytoplasm, or Golgi body. The changes are important as they infer specialization and enzymatic activity to the proteins.

In mice, the A allele causes agouti fur, the AY allele causes yellow fur and is dominant to the A allele. The homozygous AY AY genotype is lethal. Why is the AYAY homozygous condition lethal?
The AY allele lacks an upstream merc gene which is required for normal embryonic development.
The AY allele contains a null mutation in the A gene, which is required for normal embryonic development.
The yellow pigment produced by A allele is required for survival.
The AY allele highly transcribes the merc gene which is lethal in a homozygous AYAY individual.
None of the other answers are correct.

The expression of antigen A or antigen B in red blood cells requires the help of an H antigen. A recessive mutation (h) that prevents the synthesis of the H antigen also prevents the expression of A and B antigens. This is called the Bombay effect. There is no ill effect in an individual with this mutation, but complications with blood transfusions or parental disputes may arise.
a. Individuals with the Bombay genotype (hh) produce anti-H antigen. How can this be a problem during blood transfusion?

- Which of the following applies to the female sex determination in Drosophila melanogaster fruit flies? (Mark all that apply) When the X:A ratio is 1.0, the SXL gene is transcribed during the early embryonic stages. The SXL protein inhibits the expression of female differentiaion genes The SXL protein promotes the correct splicing of the Tra pre-mRNA so that functional Tra protein is made. The presence of the SXL protein promotes the correct splicing of the SXL pre-mRNA during later embryonic stages to ensure to continuous production of SXL protein. The Tra protein will stimulate the expression of male-specific genes.arrow_forwardIn humans, dosage compensation is accomplished by: inactivating one X chromosome in female somatic cells inactivating one homolog from each homologous pair of chromosomes in female somatic cells inactivating the Y chromosome in male somatic cells increasing gene expression from the X chromosome in male somatic cellarrow_forwardIn mammalian females, the majority of one X chromosome's genes are shut down in a process called X chromosome condensed and afterwards called a The inactive X is Because the shutdown is random in the embryonic cells formed by the time inactivation occurs, all mature mammalian females are a for the expression of X chromosome genes. The inactivation of one X in the female is thought to . The shutdown of the X chromosome is accomplished by the balance gene expression between males and females, a theory called gene. is the master gene for male sex determination in mammals and is found on the human Y-chromosome.arrow_forward
- The figure below shows the domains of expression of various maternal and gap genes as well as the expression pattern of the even-skipped gene. knirps (kni) represses expression of eve stripes 3, 4, 6, and 7. Which stripe enhancer (stripe 3 or stripe 4) would you expect to have higher affinity binding sites for the Knirps protein. Explain your answer.arrow_forwardHuman females who are heterozygous for an X-linked recessive allele sometimes exhibit mild expression of the trait. However, such mild expression of X-linked traits in females who are heterozygous for Xlinked alleles is not seen in Drosophila. What might cause this difference in the expression of X-linked genes between human females and female Drosophila? (Hint: In Drosophila, dosage compensation is accomplished by doubling the activity of genes on the X chromosome of males.)arrow_forwardWhich of the following best explains how individuals who inherit phenylketonuria alleles can avoid the symptoms of this disease (mental impairment, foul smelling urine)? It exhibits variable expressivity. The expression of this disease depends on the environment. If the individual removes phenylalanine from their diet they can avoid the disease entirely. PKU alleles are epistatic to alleles of another gene, which acts downstream in phenylalanine metabolism. These individuals supplement their diets with enzymes that break-down phenylalanine.arrow_forward
- Use the dropdowns to indicate the pattern of methylation and gene expression expected for a maternally-imprinted gene in the somatic cell of a male individual. The Somatic cell would show [Select] male's male parent, and [Select] male's female parent. As a result, [Select] of the allele inherited from the of the allele inherited from the could be expressed. The pattern of methylation would be [Select] imprinted gene in a somatic cell of a female individual. for the same maternally-arrow_forwardExplain why loss-of-function hedgehog and smoothened mutations yield the same phenotype in flies, but a loss-of- function patched mutation yields the opposite phenotype.arrow_forwardThe GAL gene system in yeast is used to metabolize galactose. In the presence of galactose, the GAL genes are expressed; however, in the absence of galactose, the GAL genes are repressed. A yeast mutant is discovered that continuously expresses the GAL genes in the presence or absence of galactose. Which one of the following mutations is likely the cause of constitutively expressed GAL genes? deletion of GAL4 deletion of the UAS elements in the regulatory regions of GAL genes O deletion of GAL3 O deletion of GAL80arrow_forward
- BRCA1 is mutated in a large percentage of hereditary breast and ovarian cancers. BRCA1 protein serves as a key enzyme in repairing DNA double-strand breaks. More than 800 mutations in the BRCA1 are clinically significant. This collection of mutations include missense mutations, small deletions, and large rearrangements that result in a protein with reduced function or no protein product. Inheritance of one mutant allele of BRCA1 is associated with 70-80% lifetime risk of developing breast cancer in females. How is this possible? Select all that apply. The loss of the mutant chromosome during mitosis A point mutation in the allele of BRCA1 inherited from the normal parent Repair of the heteroduplex region containing a mismatch between the normal DNA strand and the mutant DNA strand Nondisjunction of the normal chromosome during mitosis A deletion of the gene copy inherited from the affected parent Mitotic recombination in the region between the BRCA1 gene and the…arrow_forwardThere are two genes that determine the coat colour expression in some dogs: eumelanin and merle. These genes are located on two separate chromosomes. For the eumelanin gene, black coat colour (E) is dominant over red coat colour (e).
