Question
Chapter 3, Problem 2P
Interpretation Introduction
Interpretation:
The reason for the presence of identical genomes but massively divergent proteomes in two different cell types from the same organism should be determined.
Concept introduction:
In genetics and molecular biology, a genome is a genetic material present in an organism. It comprises of DNA. The genome contains both the genes and the noncoding DNA, in addition to chloroplast DNA and mitochondrial DNA. The study of the genome is known as genomics.

- Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below. The figure shows the number of cells that have clusters of IRE1 molecules after those cells are treated with various levels of thapsigargin (Tg), a chemical that can induce ER stress. IRE1 can form these clusters when ER stress is induced and this clustering can cause activation of RNAse activity in IRE1. In this experiment, normal IRE1 was used (IRE1α) that can bind to Sec61, along with a modified version of IRE1 that binds to Sec61 more weakly than normal IRE1 (wIRE1α), and another modified version that binds to Sec61 more strongly than normal IRE1 (sIRE1α). From this figure you can conclude that: Question 18 options: IRE1 binding to Sec61 promotes the formation of IRE1 clumps IRE1 binding to Sec61 prevents the formation of IRE1 clumps co-translational translocation is a key process the golgi aparatus is heavily involved in the unfolded protein response The…arrow_forwardTPA protein function.

CTP synthetase catalyzes the glutamine-dependent conversion of UTP to CTP. The enzyme is allosterically inhibited by the product, CTP. Mammalian cells defective in this allosteric inhibition are found to have a complex phenotype: They require thymidine in the growth medium, they have unbalanced nucleotide pools, and they have a mutator phenotype.
