What is the chromosomal theory of inheritance? What are the differences between natural selection and mutation? What is polygenetic traits? What are the effects of environmental factors on phenotype? What is the trait that results as a result of a change in the DNA of an organism?
A child that is tested and found to be XX chromosome has ambiguous genitalia, it is not obvious if the baby is a phenotypic boy or girl. Why? Which of the following statements is true of sex-linked traits on the X chromosome? a. Only females have sex-linked...
The somatic mutation theory Obesity is a risk factor for cancer How immunotherapy works against cancer The controversy about early cancer screening Cancer drugs can cause cancer The biggest risk factors of cancer Does eating organic food lead to less cancer? Dr. Fung’s perspective on genetically ...
Results of various cancer genome sequencing projects have "unexpectedly" challenged the framework of the current somatic gene mutation theory of cancer. The prevalence of diverse genetic heterogeneity observed in cancer questions the strategy of focusing on contributions of individual gene mutations. Much ...
The somatic mutation theory has been the basis of many cancer treatment programs. But growing evidence that cancer is a mitochondrial metabolic disease may change how researchers and doctors think about how to treat cancer in the future.
MSI induces frameshift somatic mutations within target genes harboring repeated sequences in their coding frame, including TGFβR2, which is mutated in 90% of cases. These mutations lead not only to the inactivation of these target genes but also to the appearance of potentially immunogenic neoantig...
However, there is a reduction in the number of functional AMPA receptors, and both somatic and synaptic glutamatergic currents are reduced.85–87 A number of studies have shown deficient long-term potentiation in hippocampal slices from Gria1− / − mice,84–86 although more recent studies ...

How could the structure and function of the cell be used to support evolutionary theory? What is the connection between molecular genetics and Hemochromatosis? Are gametophytes made up of somatic cells? If so, can they pass on a mutation? What is differential centrifugation? What is the conjugat...
