- What is the relationship between methylation and genomic imprinting? Differential methylation of DNA in males and females results in only one of the parental alleles being transcriptionally active in the offspring Reversible methylation of DNA inherited from the mother results in the maternal alleles being expressed early in development DNA methylation silences the alleles inherited from both parents, so no alleles are transcriptionally active. Reversible methylation of DNA inherited from the father results in the paternal alleles being expressed only late in developmentwhy some genes assort independently?Geneticists have been exploring ways to suppress the expression of the extra chromosome 21 in individuals with Down syndrome in hopes of preventing the medical problems and intellectual disability of individuals with trisomy 21. One approach involves modifying a gene that is already present in human cells and using it to suppress the expression of the extra copy of chromosome 21. What approach, do you think, are they taking, and what may be some of the challenges for using it in patients?
- In the experiments described , explain the relationshipbetween coat color and DNA methylation. How is coat colorrelated to the diet of the mother?How many protein coding genes would expect to be affected if the mutations are distributed randomly?Genes with highly similar sequence are often located adjacent one another in the genome. Gene duplication commonly arises from errors in replication. When the organization of such adjacent genes is in an inverted orientation, this can reduce the expression of other genes that have similar sequence and are located on other chromosomes. Explain the mechanism of how this generally occurs. i need a detailed explanation, please. I need to know what the mechanism is. How it happens and why. Please. Thanks
