nI agiven cel type having aspecific fuly differentiated phenotype, ti could be said that: a) Al protein coding genes are expressed. b) No genes are expressed once the differentiated cel has reached its ultimate phenotype. c) Only those genes specific to the phenotype ni question would be expressed. d) nI addition to genes commonly expressed ni al cels, the differentiated cel would express a subset of genes important for the unique functions of that differentiated cell type. e) Only genes commonly expressed in all cells would be expressed

Which of the following is/are accurate? Select all that apply. a) Only certain genes are transcribed in a given cell type b) Only the genes that are expressed in a certain cell type are present in the genome c) Two different somatic cell types in the human body have the same genes d) All genes in a cell are replicated
Md.Daniyal A.
Which of the following statements about differentiated cells is true? (a) Cells of distinct types express nonoverlapping sets of transcription factors. (b) Once a cell has differentiated, it can no longer change its gene expression. (c) Once a cell has differentiated, it will no longer need to transcribe RNA. (d) Some of the proteins found in differentiated cells are found in all cells of a multicellular organism.
Adi S.
If every somatic cell in a multicellular organism contains the same DNA, how can different cells have specialized functions? A. Once the entire genome is expressed, each cell has specialized proteases that differentially degrade proteins. B. Because different genes are enzymatically removed from the genomes of different cells within an organism, leading to differential gene expression. C. Because different genes are expressed in different cells. D. Because of TFII transcription factors. E. None of the above.
