Altered chromosome structure can drastically affect an individual organism’s phenotype. However, some types of chromosomal rearrangements are more likely to be harmful than others. Categorize the following types of rearrangements from MOST LIKELY to be harmful to LEAST LIKELY to be harmful. A. reciprocal translocation, deletion, translocation B. deletion, translocation, inversion C. inversion, translocation, reciprocal translocation D. translocation, inversion, duplication
In McCune-Albright syndrome, fibrous connective tissue replaces bone, tan patches (café-au-lait spots) dot the skin, and hormone abnormalities cause early puberty and malfunction of the thyroid, pituitary, and adrenal glands. The phenotype is highly variable, and all patients are somatic mosaics for the mutation, which is in the gene GNAS1. Why is the condition seen only in mosaics?
With regard to gene duplications, which of the following statement(s) is/are correct?a. Gene duplications may be caused by nonallelic homologousrecombination.b. Large gene duplications are more likely to be harmful thansmaller ones.c. Gene duplications are responsible for creating gene familiesthat encode proteins with similar and specialized functions.d. All of the above statements are correct.
One of the following is most suitable for study of mutations: A. Haploids B. Diploids C. Tetraploids D. Polyploid
in a paragraph discuss some examples of the effects of chromosomal mutations in humans in your own words.
For items 1-10, refer to the choices below: a. Williams Syndrome b. Cri-Du-Chat Syndrome c. Pallister-Killian Syndrome d. Wolf-Hirschhorn Syndrome 1. Caused by a deletion in chromosome 5. 2. Has bulging, wide-set eyes. 3. Has hypertelorism. 4. Caused by an isochromosome. 5. Caused by the deletion of multiple genes on chromosome 7. 6. About 30% of the people with this disorder are autistic. 7. They have an elf-like face. 8. Has a high chance of having scoliosis. 9. White starburst pattern around the iris
Assume a cell present in your body has performed a mismatch error during the process of DNA replication. This error has resulted in the generation of a new allele for one of your genes. For this new allele to be inherited by your offspring, which of the following conditions must be true? A The new allele produced must be recessive. The error must be caused by a chemical mutagen that exists in hostile environments. C The error must occur in the germ line cells responsible for the production of gametes, The error must occur in the germ line cells responsible for the production of somatic cells. 2,279 12 étv MacBook Air 80 DII DD F1 F2 F3 F4 E5 F6 F7 F8 F9 F10 11 @ %23 2$ & *
When recombination (“crossing over”) doesn’t happen correctly, what type(s) of mutations that can occur? circle all that apply Select one or more: a. Inversion (reversal or “flipping” of part of a chromosome) b. Duplication of part of a chromosome c. Translocation (transfer of part of a chromosome to a non-homologous chromosome) d. Deletion of part of a chromosome
a. How would you synthesize a pentaploid?b. How would you synthesize a triploid of genotypeA/a/a?c. You have just obtained a rare recessive mutation a*in a diploid plant, which Mendelian analysis tells you isA/a*. From this plant, how would you synthesize atetraploid (4n) of genotype A/A/a*/a*?d. How would you synthesize a tetraploid of genotypeA/a/a/a?
Which type(s) of chromosomal aberrations is/are likely to cause semisterility? Select all correct answers. A.)reciprocal translocations B.)deletions C.)inversions D.) duplications
During the course of a research project you generate a gene knockout line in Arabidopsis thaliana to study the function of a gene you believe plays a crucial role in cellular metabolism. You note that the initial transformants are a bit smaller than normal. In subsequent crosses you are unable to isolate homozygotes for the knockout allele. Heterozygotes in subsequent generation are still a bit smaller than the homozygous wild type plants. Explain what is happening.
The origin of genes that have new functions often involves the divergence of gene duplicates.Duplicates can arise via several mechanisms. a. One mechanism of gene duplication is retrotransposition, the insertion into the genome of DNA produced by reverse transcription of a messenger RNA. These gene duplicates are often dead on arrival: they are pseudogenes as soon as they are formed. Why are such duplicates so often dead on arrival? b. A second mechanism of gene duplication occurs via unequal crossing over during meiosis. Gene duplicates formed this way are functional more often than when they arise by reverse transcription. Why is that? c. If a gene duplicate is initially functional, what are its possible ultimate fates? Which is most likely,and why?
