What is the role of DNA in genetics and heredity? (a) How does DNA methylation affect gene expression? (b) What characteristic of DNA allows methylation patterns to be maintained through replication and cell division? Describe what acetylation-deacetylation and methylation-demethylation of ...

What is PRDM9 and what DNA motif does it likely bind? What are mutations and their impact on a DNA sequence? What connect genetic material, DNA and RNA in genetics? What is a transposon? a. A plasmid b. A piece of the chromosome c. A "jumping" gene d. Transferable RNA ...
Genomic imprinting is an epigenetic gene silencing phenomenon that is specific to eutherians in the vertebrate lineage. The acquisition of both placentation and genomic imprinting has spurred interest in the possible evolutionary link for many years. In this review we examine the genetic evidence and ...
What are the limitations of Mendelian genetics? Limitations. Mendel's laws apply widely, but not to all living things.They apply to any organism which is diploid (has two paired sets of chromosomes)and which engages in sexual reproduction. They would not apply to bacteria, for example, or to...
However, in real-life genetics, this is not the case. Instead, it has been found that multiple genes often influence specific traits in the expressed phenotype of the organism. Examples of this would be pigmentation in parts of organisms or the final size of the organism. How dominant or ...
However, there are some instances wherein the epigenetic tags are carried forward as they are. This is referred to as imprinting, wherein a few epigenetic markers get preserved. As a result, perhaps only the mother’s copy or the father’s copy will be used later to form the protein. ...
The study of sexual dimorphism in psychiatric and neurodevelopmental disorders is challenging due to the complex interplay of diverse biological, psychological, and social factors. Males are more susceptible to neurodevelopmental disorders including inte
Is there a genetic mutation that has produced a protein? Which type of mutation occurs when a piece of DNA is cut, rotated, and the re-inserted? a. nucleotide substitution b. insertion mutation c. deletion mutation d. inversion In genetics, what type of point mutation results in the chang...
What is the detailed meaning of the term genetics? Define gene, trait, and chromosome. What is epigenetics and what is genomic imprinting? Mutations in homeotic genes can lead to what type of developmental defect? What is the significance of 'F' in heredity?
