Housekeeping genes are the constitutive genes that are required to maintain basic cellular function. These genes are expressed in both normal and patho-physiological conditions. The rate of their expression varies with experimental conditions but some genes express at constant levels in different patho-physiological conditions. Proper segregation of housekeeping proteins maintains stable patterns of gene expression during cell division.
Hence, the correct option among the following is d.

Which of the following is not true regarding regulation of gene expression in eukaryotes? In eukaryotic cells, transcriptional activators often work by recruiting the transcriptional macinery to gene promoters DNA methylation is an example of an epigenetic mark that can be inherited Acetylation of histones can result in a more open chromatin structure to allow transcription to occur Different genes can be turned off or on between different organs or stages of development Transcription factor DNA sequences are bound by...

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.

Could you please provide the best answer for following MCQs. Thank you. Question 1 The imprinting control region is best defined as a promoter that regulates the expression of MeCP2 a sequence that can be methylated or unmethylated to control the expression of one or more genes by regulating promoter-enhancer interactions a sequence that when unmethylated can bind RNA polymerase II to induce promoter activation an enhancer that is inhibited when methylated Question 2 Imprinting is best described as a...

32. Study the signaling pathway illustrated below, which involves two different receptors. Assume that a protein is active only when it is activated, but not inhibited, by its upstream signaling molecules. Activation and inhibition are indicated by normal and blunt arrows, respectively. Assume that the transcription regulator can be activated by either the binding protein or the kinase that are immediately upstream of the transcription factor. Under which of the following conditions will the expression of target:gene "X" be induced?...
