Cells are competing for limited resources and mutations help some cells outcompete others
Cells are dying faster than they can be replaced
Cells are devoted to growing as quickly as possible given the conditions
Cells are changing their gene regulation patterns to prepare for growth
Dying cells are being replaced by newly divided cells
How does gene expression influence the behavior of cells that contain the same genome (genetic information)? In other words, why do cells that belong to the same multicellular organism have a different structure and function?

They are useful because of the following characteristics except: they have homologs of many human genes they have provided valuable insights into how human genes function. they can be used to study complex cell-cell interactions they can be used to manufacture of antibiotics and other chemicals their small size and short life-cycle make it easy to culture them in the laharrow_forward
- How do changes in gene expression relate to cell differentiation and specialization? Does every human cell have the same DNA, RNA or proteins?arrow_forwardThere are close to 200 different cell types in the human body. Why do they look and function differently from one another? O They each express a different set of genes O They each express all the same genes, but in a different order at different times O They each have slightly different genomes O They all express the same genes, but proteins that aren't needed in a particular cell type are degraded before they can function QUESTION 10 When you exercise, you typically start breathing harder. This is because: O You are switching from aerobic to anaerobic respiration O More oxygen is needed to meet the increased ATP demand O Carbon dioxide stores are quickly depleted during exercise Muscle cells can only use aerobic respirationarrow_forwardMutations in DNA may or may not result in a change in the phenotype of an organism. In which of the following situations will a mutation appear in the phenotype of an individual? The mutation occurs in an organism which is past reproductive age The genetic code for protein synthesis has not been altered in a gamete producing cell The mutation occurs in a body cell of the organism, resulting in cancer O The mutation results in a change in the amino acid sequence of the protein in a gamete producing cellarrow_forward
- In 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a person's own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwang's group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?arrow_forwardSuppose that a rare DNA replication error results in the duplication of a single gene, giving the daughter cell two copies of the same gene. How does this change favor the acquisition of a new function by the daughter cell? The copy can undergo a gain-of-function or loss-of-function mutation without altering the original gene's function. The copy has already-formed domains with biological activity, so new functions do not need to evolve de novo. The duplicated gene increases the rate at which the cell can perform the function encoded by the original gene. The two genes can combine to form a new gene that encodes a protein with a new, additional function. The cell can make additional proteins, which then undergo alterations and can give rise to new functions.arrow_forwardEvery cell contains all of the DNA for an organism. What controls when and how specific genes are expressed? Genes are not controlled, all genes are expressed all the time Gene expression is controlled by sequences in the DNA Gene expression is controlled by proteins Gene expression can be controlled by proteins and sequences in the DNA O 000arrow_forward
