Which of the following statements regarding loss of function and gain of function mutations is true? A. If both gain of function and loss of function approaches show the consistent results it is the most convincing evidence to demonstrate the function of gene B. Gain of function mute tapes are the most of case recessive C. Gain of function approach is more convincing than loss of function approach D. Over expression of a gene cannot be considered as gain of function
A female born with Angelman syndrome carries a deletion in theAS gene (i.e., the UBE3A gene). Which parent transmitted thedeletion to her?a. Her father c. Either her mother or fatherb. Her mother
For gain-of-function disorders, which of the following treatment strategies is the be . A. Gene augmentation B.Supply healthy cells . C.Supply normal form of proteins encoded by wild-type allele . D. Gene silencing
The only thing that effects gene expression is if the gene is dominant Choose: A. Yes, all genes are either dominant or recessive B. No, all dominant genes are the best option but might not be expressed C. No, there are other factors that can determine gene expression D. Yes, all genes can be expressed if your cell wants to
Which of the following statements does NOT describe an environmental influence on the expression of a gene? Select one: a. Siamese cats have darkened paws, nose, and tip of tail due to a gene that allows their skin and fur to darken in the parts of their bodies that need to retain more heat, their extremities. b. More than a single gene is involved in the expression of human height, weight, and skin colour. c. Exposure to sunlight increases melanin production in human skin. d. Colder incubation temperatures of gecko eggs yield more females and warmer temperatures yield more males.
Genomic imprinting refers to the fact that A. some proteins are made from mRNA transcribed by the mother B. one cell type follows the developmental path of another C. the X-ray repair system is inactivated D. programmed cell death occurs E. gene activity depends upon whether the gene is of maternal or paternal origin
Protein levels and mRNA levels for a particualr gene don’t always match. For example, the GCN4 gene in yeast is always producing mRNA, but the Gcn4 protein is only made when the cells are starved. B. What does this mean for diagnostic techniques that try to look at gene expression?
D An epistatic gene A is a gene that is A at a different location than gene B and that is capable of suppressing gene B B) very close to gene B and thus they will be passed together to the offspring at the same location as gene B and thus their expression is similar far from gene B and can increase the expression of gene B
I am confused about how stem cell transplants works. If you put a semi differentiated tadpole nucleus in a denucleated egg cell, it’ll develop into a fully formed tadpole, but if you put a fully differentiated tadpole nucleus, it won’t (because the genes have already been expressed in a way where the cytoplasmic determinants cannot operate to the fullest). Then how come in stem cell transplants, you use adult nucleuses that are already developed and transplant them into the denucleated egg cells?
A. Somatic cells are aslo called B. In irder to clone a gene, a gene is inserted into a:
Epigenesis relating to genetics refers to which of the following A. Genetic information is limited to what we inherit only from our biological parents. B. Genes are not influenced by environmental factors. C. Genes we inherit are fully expressed at birth. D. Genes are turned on or off as needed, by the developing body or environmental triggers, across the life-span
