Question
Chapter 1, Problem 34P
Interpretation Introduction
Interpretation:
The number of possible different cell types if each cell expresses 10 sets of the genes should be calculated.
Concept introduction:
The study of epigenetic variation or modifications in a set of genomes is termed as the epigenomics. Epigenetic modifications do not alter the DNA sequence but affects the gene expressions. Moreover, it is reversible modification in the cell’s DNA or histone sequence.

that the CRISPRICas9 system will impact both copies of Gene Y in cells, and that the first exon of
Gene Y is necessary for Gene Ys function.

- can you please help me out with this ? Mutations in the IL2RG gene cause approximately 30 percent of severe combined immunodeficiency disorder (SCID) cases in humans. These mutations result in alterations to a protein component of cytokine receptors that are essential for proper development of the immune system. The IL2RG gene is composed of eight exons and contains upstream and downstream sequences that are necessary for proper transcription and translation. Below are some of the mutations observed. For each, explain its likely influence on the IL2RG gene product (assume its length to be 375 amino acids).

In the technique of DNase I footprinting, the binding of a protein to a region of DNA protects that region from digestion by DNase I by blocking the ability of DNase I to gain access to the DNA. In the DNase I footprinting experiment shown here, a researcher began with a sample of cloned DNA 400 bp in length. This DNA contained a eukaryotic promoter for RNA polymerase II. The assembly of general transcription factors and RNA polymerase II at the core promoter is described in Chapter 12 (see Figure 12.14). For the sample loaded in lane 1, no proteins were added. For the sample loaded in lane 2, the 400-bp fragment was mixed with RNA polymerase II plus TFIID and TFIIB. 2 400 350 250 175 50 Which region of this 400-bp fragment of DNA is bound by RNA polymerase II and TFIID and TFIIB? || III ||| | ||||arrow_forward
