A field experiment is conducted to test for a heterozygote advantage in the survival of a mustard plant. When heterozygotes for the A locus are first crossed, the yield is 200 AA, 400 Aa, and 200 aa ( i.e., a ratio of 1:2:1). In trial 1, 35 AA, 44 Aa, and 23 aa plants survive. In trial 2, 25 AA, 68 Aa, and 21 aa plants survive. Based on […]
Diseases are used to study the impact of dysregulated genes and cells. Use different genetic diseases (including cancer if you wish) from this course to provide specific examples of the following course topics: (a) Non-coding RNAs (b) DNA methylation (c) histone modification or chromatin proteins
Epigenetics and complex gene regulation have fundamentally altered the way we deal with bioinformatics and biotechnology. Give specific examples from this course that disprove the following old beliefs, focusing on epigenetic rather than genetic events: (a) phenotype is controlled by genotype (i.e. DNA sequence) (b) cancer cell lines are useful models for studying normal gene […]
Compare and contrast conventional breeding and plant genetic engineering and list three methods that could be used to transfer a gene from one species to another using genetic engineering
Epigenetics and complex gene regulation have fundamentally altered the way we deal with bioinformatics and biotechnology. Give specific examples (not generalities) in detail that disprove the following old beliefs, focusing on epigenetic rather than genetic events:
Diseases are used to study the impact of dysregulated genes and cells. Use Rett Syndrome, Huntington’s Disease, and Crohn’s Disease to provide specific examples of the following topics: (a) Non-coding RNAs (b) DNA methylation (c) histone modification or chromatin proteins
What is meant by genetic variation in relation to polymorphism and mutation? Explain and give example.
