Concept explainers

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.

The floral homeotic genes of Arabidopsis belong to the MADS-box gene family, while in Drosophila, homeotic genes belong to the homeobox gene family. In both Arabidopsis and Drosophila, members of the Polycomb gene family control expression of these divergent homeotic genes. How do Polycomb genes control expression of two very different sets of homeotic genes?
When the organization of adjacent genes with highly similar sequences is in an inverted orientation, this can reduce the expression of other genes that have similar sequence and are located on other chromosomes. Explain the mechanism of how this generally occurs.
In a haploid, a nonsense suppressor su1 acts on mutation1 but not on mutation 2 or 3 of gene P. An unlinked nonsense suppressor su2 works on P mutation 2 but not on 1or 3. Explain this pattern of suppression in regard to thenature of the mutations and the suppressors.
The human body contains many distinct cell types yet almost all human cells contain the same genome with 21,000 genes. The distinct cell types are primarily due to differences in gene expression. Assume that one set of 1000 genes is expressed in all cell types and that the remaining 20,000 genes can be divided into sets of 1000 genes that are either all expressed or all not expressed in a given cell type. How many different cell types are possible if each cell type expresses 10 sets of these genes? Note that the number of combinations of n objects into m sets is given by n !/ (m!(n-m)!) where n! = 1*2*…*(n 2 1)*n.
IPSCs are nearly identical to human embryonic stemcells in terms of gene expression, but there may be otherways in which they are not equivalent. For example, thetelomeres of IPSCs often vary in length, with many IPSCscells having telomeres shorter than those of embryonic.How might shortened telomeres affect the life-span ofIPSCs or of differentiated cells derived from them?
The GAL gene system in yeast is used to metabolize galactose. In the presence of galactose, the GAL genes are expressed; however, in the absence of galactose, the GAL genes are repressed. A yeast mutant is discovered that continuously expresses the GAL genes in the presence or absence of galactose. Which one of the following mutations is likely the cause of constitutively expressed GAL genes? deletion of GAL4 deletion of the UAS elements in the regulatory regions of GAL genes O deletion of GAL3 O deletion of GAL80
Please answer A mutation within an enhancer sequence regulating the expression of the ABC1 gene was discovered.

Use the dropdowns to indicate the pattern of methylation and gene expression expected for a maternally-imprinted gene in the somatic cell of a male individual. The Somatic cell would show [Select] male's male parent, and [Select] male's female parent. As a result, [Select] of the allele inherited from the of the allele inherited from the could be expressed. The pattern of methylation would be [Select] imprinted gene in a somatic cell of a female individual. for the same maternally-
In times of nutrient stress, the cellular slime mold Dictyostelium discoideum develops one of two cell types: pre-stalk and pre-spore. Scientists studying this development discovered that the pH of individual cells regulates the type of cell that is formed. Which of the following claims could scientists make about how environmental cues affect the gene expression of Dictyostelium discoideum? A - A response to nutrient deprivation leads to a change in pH that causes mutation in the cells, forming the different cell types. B - A response to nutrient deprivation leads to a change in pH that disrupts the cells, forcing them to develop into certain cell types. C - A response to environmental stress leads to a change in pH that triggers transcription factors to differentiate the cell type that will be formed. D - A response to environmental stress leads to a change in pH and a decrease in transcription factors that differentiate the cell type that will be formed.
