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 ...

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 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...
depending on whether they are inherited from mother or father, a phenomenon called genomic imprinting. A gene that affects birth weight in humans, the Igf2 gene, for example, is actively expressed in the fetus and placenta if it's inherited from the father but silenced if it came from the...
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 ...

What is the major difference between a trait and a gene as defined in genetics? What is a genetic experiment involving a single trait? What is the most common genetic mutation? What are genetic mutations? What are some examples of heredity?
What is the major difference between a trait and a gene as defined in genetics? What are some of the advantages of gene duplication? Explain the two mechanism that miRNA can regulate gene expression. Briefly explain what we are trying to accomplish with gene editing. ...
