The tumor DNA sample of valerie have fewer bands than the peripheral blood because her tumor profile signifies a digest where equally alleles are mutated bring about in a pattern which is a subset of that got from the peripheral blood and her blood is heterozygous for the mutation but the tumor has a homozygous mutant genotype.
Answer;
d. allows a geologist to predict what minerals will be found in a given igneous rock.
Explanation;
-Bowen's reaction series was deduced through laboratory procedures that cooled molten rock; the crystal formation in the igneous rocks produced always followed the same order.
-Bowen's Reaction Series is a proposed sequence of mineral crystallization from basaltic magma, based on experimental evidence. it is a schematic description of the order in which minerals form during the cooling and solidification of magma and of the way the newly formed minerals react with the remaining magma to form yet another series of minerals.
Answer:
Explanation:
The VHL gene is a tumour suppressor gene that regulates cell growth and cell death. This gene is also located on chromosome 3. It functions to prevent rapid proliferation of cells. For a person to develop tumor both copies of the gene must be mistake or altered allowing for a loss of function that prevents its from causing degradation of HIF1α in the normal oxygen level as its it normal function. This then allows for the survival of HIF1α that promotes amgiogenesis promoting tumor development.
Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli.
