Homework Answers
1) Axis HC3 and AxD1 have a different level of gene expression as compared to with same cell types.
2) Axis HC1, HC2, and HC3 have one type of cell type and axis AxD1, AxD2, and AxD3 have another type of cell type.
3) Gene A is the most upregulated gene in AxD cells.
4) Gene D is most upregulated in HC cells.
5) Z-score is a number that represents a value's relationship to the mean value. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score. A Z-score of 1.0 would indicate a value that is one standard deviation from the mean. Z-scores may be positive or negative, with a positive value indicating the score is above the mean and a negative score indicating it is below the mean.
So basically, we are comparing the SAD1 gene expression value with the mean.

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.

In humans, there are about 200 different types of cells. Why are your liver cells different from skin cells, or neurons, or muscle cells? During development, each cell accumulates different mutations changing their DNA They produce the same proteins but some of those proteins are denatured in each cell They have different DNA and thus, each cell produces different proteins They produce the same kind of proteins but not all proteins are active in each cell They have the same...

Which of the following statements is false? Epistasis involves interactions among different genes, to influence phenotype. When an allele is dominant, the heterozygous combination is the same phenotypically as one of the homozygotes. Dominance refers to the form of expression of a gene in relation to its allele (or alleles). Epistasis involves interactions between alleles of a single gene.

Which of the following are true of modifying and epistatic genes in regard to genetic diseases? (1) Modifying genes can account for the severity of a genetic disease Modifying genes do not completely mask genes for a genetic disease. Epistatic genes may cause a disease by masking normal genes.
